DIESEL FUEL LUBRICATION  

SciTech Connect

The diesel fuel injector and pump systems contain many sliding interfaces that rely for lubrication upon the fuels. The combination of the poor fuel lubricity and extremely tight geometric clearance between the plunger and bore makes the diesel fuel injector vulnerable to scuffing damage that severely limits the engine life. In order to meet the upcoming stricter diesel emission regulations and higher engine efficiency requirements, further fuel refinements that will result in even lower fuel lubricity due to the removal of essential lubricating compounds, more stringent operation conditions, and tighter geometric clearances are needed. These are expected to increase the scuffing and wear vulnerability of the diesel fuel injection and pump systems. In this chapter, two approaches are discussed to address this issue: (1) increasing fuel lubricity by introducing effective lubricity additives or alternative fuels, such as biodiesel, and (2) improving the fuel injector scuffing-resistance by using advanced materials and/or surface engineering processes. The developing status of the fuel modification approach is reviewed to cover topics including fuel lubricity origins, lubricity improvers, alternative fuels, and standard fuel lubricity tests. The discussion of the materials approach is focused on the methodology development for detection of the onset of scuffing and evaluation of the material scuffing characteristics.

Diesel engine lubrication with poor quality residual fuel  

SciTech Connect

The quality of marine residual fuel is declining. This is being caused by a gradual trend towards production of heavier crudes and increased residuum conversion processes in refineries to meet light product demand while holding down crude runs. Additionally, more stringent inland fuel sulfur regulations have caused the higher sulfur residues to be used for marine residual fuel blending. Engine manufacturers are making major efforts in design so that their engines can burn these fuels at high efficiency with minimum adverse effects. The oil industry is developing improved lubricants to reduce as much as possible the increased wear and deposit formation caused by these poor quality fuels. To guide the development of improved lubricants, knowledge is required about the impact of the main fuel characteristics on lubrication. This paper summarizes work conducted to assess the impact of fuel sulfur, Conradson carbon and asphaltenes on wear and deposit formation in engines representative of full scale crosshead diesel engines and medium speed trunk piston engines. Results obtained with improved lubricants in these engines are reviewed.

Design and testing of a procedure for evaluating fuel-efficient crankcase lubricants  

SciTech Connect

Experiments were conducted to design and evaluate a procedure for evaluating the fuel efficiency characteristics of crankcase lubricants using the driving cycles of the 1975 Federal Test Procedure and the Highway Fuel Economy Test. Most of the test protocol was based on guidelines proposed by the American Society for Testing and Materials. Three crankcase lubricants and five oil supplements, as well as a baseline lubricant, were used in eight 1980 model-year vehicles of identical make. The vehicles were operated at 75/sup 0/F (24/sup 0/C) in closely controlled chassis dynamometer tests designed to detect small changes in fuel efficiency. Results from these tests showed measurable increases in fuel economy of 0 to 6% with the test lubricants when compared to a common SAE 30 grade oil. These results are not definitive because of lack of quantification of mileage accumulation effects. The test protocol did reduce measurement variability greatly; this procedure can be applied to evaluation of fuel-efficient oils using larger test fleets. A good potential exists for improving the fuel economy of the US automotive fleet. Because of the large quantities of petroleum consumed in the automotive sector, this potential savings translates into conserving a very significant quantity of petroleum.

Effects of moisture on wear of components lubricated with diesel fuel. Interim report, May 1996--September 1997  

SciTech Connect

The durability of some fuel injection systems on compression-ignition engines will be adversely affected by fuels of significantly low lubricity. Previous work has shown that fuel-lubricated wear is sensitive to the availability of moisture, particularly in severely refined fuels, which are designed to minimize exhaust emissions. The effects of moisture may be particularly relevant in a marine environment in which sea water is used as ballast in the fuel tanks. Traditional, less-refined fuels contain natural corrosion inhibitors that reduce oxidative wear, although alternate wear mechanisms may still affect long-term durability. However, no detailed study bas been performed to define the effects of water contamination and its relationship to fuel composition. Standardized laboratory-scale tests that show good correlation with wear in full-scale fuel injection systems for ground vehicles are available. In the present work, the standard procedures for the HFRR and BOCLE/SLBOCLE apparatus were modified to show the effects of both dissolved and emulsified water on fuel-lubricated wear. The results indicate that the lubricity of all but the most severely hydrotreated fuels are insensitive to contamination by either deionized or salt water. Moreover, the relatively short aeration period used in the ASTM D 5001 and D 6078 BOCLE test procedures has no measurable effect on water concentration in the test fuel sample.

Lubricants Lubricants As most vehicles are on the road for more than 15 years before they are retired, investigating technologies that will improve today's vehicles is essential. Because 11.5 percent of fuel energy is consumed by engine friction, decreasing this friction through lubricants can lead to substantial improvements in the fuel economy of current vehicles, without needing to wait for the fleet to turn over. In fact, a 1 percent fuel savings in the existing vehicle fleet possible through lubricants could save 97 thousand barrels of oil a day or $3.5 billion a year. Because of these benefits, the Vehicle Technologies Office supports research on lubricants that can improve the efficiency of internal combustion engine vehicles, complementing our work on advanced combustion engine technology.

SOLAR HEATING OF TANK BOTTOMS Application of Solar Heating to Asphaltic and Parrafinic Oils Reducing Fuel Costs and Greenhouse Gases Due to Use of Natural Gas and Propane  

SciTech Connect

The sale of crude oil requires that the crude meet product specifications for BS&W, temperature, pour point and API gravity. The physical characteristics of the crude such as pour point and viscosity effect the efficient loading, transport, and unloading of the crude oil. In many cases, the crude oil has either a very high paraffin content or asphalt content which will require either hot oiling or the addition of diluents to the crude oil to reduce the viscosity and the pour point of the oil allowing the crude oil to be readily loaded on to the transport. Marginal wells are significantly impacted by the cost of preheating the oil to an appropriate temperature to allow for ease of transport. Highly paraffinic and asphaltic oils exist throughout the D-J basin and generally require pretreatment during cold months prior to sales. The current study addresses the use of solar energy to heat tank bottoms and improves the overall efficiency and operational reliability of stripper wells.

Asphalt Roofing Shingles Into Energy Project Summary Report  

SciTech Connect

Based on a widely cited September, 1999 report by the Vermont Agency of Natural Resources, nearly 11 million tons of asphalt roofing shingle wastes are produced in the United States each year. Recent data suggests that the total is made up of about 9.4 million tons from roofing tear-offs and about 1.6 million tons from manufacturing scrap. Developing beneficial uses for these materials would conserve natural resources, promote protection of the environment and strengthen the economy. This project explored the feasibility of using chipped asphalt shingle materials in cement manufacturing kilns and circulating fluidized bed (CFB) boilers. A method of enhancing the value of chipped shingle materials for use as fuel by removing certain fractions for use as substitute raw materials for the manufacture of new shingles was also explored. Procedures were developed to prevent asbestos containing materials from being processed at the chipping facilities, and the frequency of the occurrence of asbestos in residential roofing tear-off materials was evaluated. The economic feasibility of each potential use was evaluated based on experience gained during the project and on a review of the well established use of shingle materials in hot mix asphalt. This project demonstrated that chipped asphalt shingle materials can be suitable for use as fuel in circulating fluidized boilers and cement kilns. More experience would be necessary to determine the full benefits that could be derived and to discover long term effects, but no technical barriers to full scale commercial use of chipped asphalt shingle materials in these applications were discovered. While the technical feasibility of various options was demonstrated, only the use of asphalt shingle materials in hot mix asphalt applications is currently viable economically.

Ionic Liquids as Novel Lubricants and /or Lubricant Additives  

SciTech Connect

This ORNL-GM CRADA developed ionic liquids (ILs) as novel lubricants or oil additives for engine lubrication. A new group of oil-miscible ILs have been designed and synthesized with high thermal stability, non-corrosiveness, excellent wettability, and most importantly effective anti-scuffing/anti-wear and friction reduction characteristics. Mechanistic analysis attributes the superior lubricating performance of IL additives to their physical and chemical interactions with metallic surfaces. Working with a leading lubricant formulation company, the team has successfully developed a prototype low-viscosity engine oil using a phosphonium-phosphate IL as an anti-wear additive. Tribological bench tests of the IL-additized formulated oil showed 20-33% lower friction in mixed and elastohydrodynamic lubrication and 38-92% lower wear in boundary lubrication when compared with commercial Mobil 1 and Mobil Clean 5W-30 engine oils. High-temperature, high load (HTHL) full-size engine tests confirmed the excellent anti-wear performance for the IL-additized engine oil. Sequence VID engine dynamometer tests demonstrated an improved fuel economy by >2% for this IL-additized engine oil benchmarked against the Mobil 1 5W-30 oil. In addition, accelerated catalyst aging tests suggest that the IL additive may potentially have less adverse impact on three-way catalysts compared to the conventional ZDDP. Follow-on research is needed for further development and optimization of IL chemistry and oil formulation to fully meet ILSAC GF-5 specifications and further enhance the automotive engine efficiency and durability.

Synthesis of new high performance lubricants and solid lubricants  

SciTech Connect

In our second year of funding we began the testing phase of a number of new classes of lubricants. Three different testing collaborations have already begun and a fourth one is In the works with Dr. Stephen Hsu of the National Institute of Standards and Technology. Dr. Hsu also plans to test some of the same materials for us that Shell Development is studying. With Dr. Bill Jones of NASA, we are studying the effects of branching an high temperature lubricant properties in perfluoropolyethers, Initially Bill Jones is comparing the lubrication and physical properties of perfluorotetraglyme and the following two spherical perfluoropolyethers, Note that one contains a fluorocarbon chain and the other one contains a fluorocarbon ether chain. The synthesis of these was reported in the last progress report. With Professor Patricia Thiel of Iowa State University, we are working on studies of perfluoromethylene oxide ethers and have prepared a series of four of these polyethers to study in collaboration with her research group. These perfluoromethylene oxide ethers have the best low temperature properties of any known lubricants. Thiel's group is studying their interactions with metals under extreme conditions. Thirdly, we have also begun an Interaction with W. August Birke of Shell Development Company in Houston for whom we have already prepared samples of the chlorine-substituted fluorocarbon polyether lubricants whose structures appear on page 54 of our research proposal. Each of these four structures is thought to have potential as lubricant additives to motor oils. We also have underway syntheses of other fluorine-containing branched ether lubricants. These new materials which are also promising as antifriction additives for motor oils appear ahead of the perfluoro additives as Appendix I to the progress report. Additionally for Birke and Shell Development we have at their request prepared the novel compound perfluoro salicylic acid. This synthesis was suggested by the Shell staff who thought that esters of perfluoro salicylic acid might be an excellent antifriction additive for motor oil fuels. One of the best additives currently used in motor oils is the hydrocarbon ester of salicylic acid.

Advanced lubrication systems and materials. Final report  

SciTech Connect

This report described the work conducted at the National Institute of Standards and Technology under an interagency agreement signed in September 1992 between DOE and NIST for 5 years. The interagency agreement envisions continual funding from DOE to support the development of fuel efficient, low emission engine technologies in terms of lubrication, friction, and wear control encountered in the development of advanced transportation technologies. However, in 1994, the DOE office of transportation technologies was reorganized and the tribology program was dissolved. The work at NIST therefore continued at a low level without further funding from DOE. The work continued to support transportation technologies in the development of fuel efficient, low emission engine development. Under this program, significant progress has been made in advancing the state of the art of lubrication technology for advanced engine research and development. Some of the highlights are: (1) developed an advanced high temperature liquid lubricant capable of sustaining high temperatures in a prototype heat engine; (2) developed a novel liquid lubricant which potentially could lower the emission of heavy duty diesel engines; (3) developed lubricant chemistries for ceramics used in the heat engines; (4) developed application maps for ceramic lubricant chemistry combinations for design purpose; and (5) developed novel test methods to screen lubricant chemistries for automotive air-conditioning compressors lubricated by R-134a (Freon substitute). Most of these findings have been reported to the DOE program office through Argonne National Laboratory who manages the overall program. A list of those reports and a copy of the report submitted to the Argonne National Laboratory is attached in Appendix A. Additional reports have also been submitted separately to DOE program managers. These are attached in Appendix B.

4 - Hydrodynamic Lubrication  

Science Journals Connector (OSTI)

Publisher Summary In this chapter the basic principles of hydrodynamic lubrication are discussed. The mechanisms of hydrodynamic film generation and the effects of operating variables such as velocity, temperature, load, design parameters, etc., on the performance of such films are outlined. These are explained using bearings commonly found in many engineering applications as examples. Secondary effects in hydrodynamic lubrication such as viscous heating, compressible and non-Newtonian lubricants, bearing-vibration and deformation are described and their influence on bearing-performance assessed. The complete separation of sliding surfaces by a liquid film under full hydrodynamic lubrication can allow bearings to operate indefinitely without any wear. Any liquid or gas can be used for this form of lubrication, provided that no chemical attack on the bearing occurs. The disadvantage of hydrodynamic lubrication is that a non-zero sliding or “squeeze” velocity is required before load capacity is obtained. Some damage to bearings during starting or stopping is inevitable because of this condition. Vibration induced by hydrodynamic instability may occur during operation at high speeds and this should always be carefully controlled. Despite these deficiencies, hydrodynamic lubrication is the preferred form of lubrication in most bearing systems.

Improved paving asphalt from Baku crudes  

SciTech Connect

An improved paving asphalt has been obtained from commercial BN-60/90 asphalt by adding certain components that are waste materials in petroleum refining: a still residue from the distillation of naphthenic acids to improve adhesion properties, asphalt obtained in deasphalting vacuum resid to improve ductility and impart freeze resistance, and a dialkylnaphthalene as a pour point depressant. Three different blend formulations were prepared by melting and mixing and analyzed for their physicochemical properties. The possibility was also investigated of expanding the raw material base for paving asphalts by including certain waste materials obtained in refining Baku crudes.

4 Hydrodynamic Lubrication  

Science Journals Connector (OSTI)

Publisher Summary This chapter discusses the theory of hydrodynamic lubrication. The chapter demonstrates how a basic property of all liquids, such as viscosity, can be used to produce cheap, reliable bearings that operate with low friction and wear. The mechanisms of hydrodynamic film generation and the effects of operating variables such as velocity, temperature, load, design parameters, etc., on the performance of such films are outlined. This is explained using bearings commonly found in many engineering applications as examples. Secondary effects in hydrodynamic lubrication such as viscous heating, compressible and non-Newtonian lubricants, bearing vibration and deformation is described and their influence on bearing performance is assessed. Like many important scientific principles, chance observation played an important role in the recognition of hydrodynamic action as a basic mechanism of bearing lubrication. The complete separation of sliding surfaces by a liquid film under full hydrodynamic lubrication can allow bearings to operate indefinitely without any wear. Any liquid or gas can be used for this form of lubrication provided that no chemical attack of the bearing occurs. The disadvantage of hydrodynamic lubrication is that a non-zero sliding or “squeeze” velocity is required before load capacity is obtained.

14 - Lubricant use and disposal  

Science Journals Connector (OSTI)

Abstract: Criteria are defined for optimum machine-specific selection of conventional, high-performance and specialty lubricants. Lubrication consolidation is indicated as a means of rationalisation of inventories. Intended use of lubricants may be compromised by oxidation, water and air contamination, additive depletion and accumulation of contaminants, including wear debris, and biological degradation. Strategic oil analysis is described from simple in-shop sensory inspections to primary on-site standard testing and more comprehensive secondary testing methods as an operational maintenance tool for machine and lubricant condition monitoring to estimate remaining lubricant life time and prevent premature machine failure. The disposal of spent lubricants, including waste oil legislation and management, and re-refining technologies, are discussed.

Effect of sulfur on heavy duty diesel engine lubricants  

SciTech Connect

Diesel engine exhaust legislation has become quite onerous for heavy duty engines. Yet, these high thermal efficiency engines continue to meet lower exhaust particulate and NOx emissions limits, due to new engine designs and the complementary engine oil performance requirements of the API service categories. In addition, the EPA has mandated changes in on-highway diesel fuel to help meet particulate emissions regulations. On October 1, 1993, when the EPA outlawed high sulfur fuels for on-highway use, the development of the API CG-4 engine oil performance specification was already in progress. All the new diesel engine tests in the category were therefore designed to run with low (< 0.05% wt.) sulfur fuel. In some engine tests, this new fuel improved some lubricant performance characteristics and degraded others. An engine oil specification for low sulfur fuel brings new challenges to developing future specifications for diesel engine oils. Both higher and lower lubricant additive treat rate products, high performance single grade oils, and formulations to meet world-wide specifications become viable. This paper discusses the results of a diesel engine oil technology that performs well with the new, low sulfur fuel in both engine tests and in the field.

Composition of paraffinic and naphthenic hydrocarbons in petroleum asphalts  

SciTech Connect

Uses a combination of chromatographic, chemical, and spectroscopic methods to determine the composition of the paraffinic and naphthenic hydrocarbons recovered from asphalts. Monitors the completeness of separation of the hydrocarbons from the aromatics on the basis of UV spectra. Finds that in the mixture of adduct-forming hydrocarbons, along with the n-paraffins there were admixtures of isoparaffins and longchain alkylnaphthenes. Concludes that a comparison of the structural-group composition of the asphalt fractions from the different crudes shows that there are only slight differences in the structure of the paraffinic/naphthenic hydrocarbons present in these asphalts, particularly with regard to those hydrocarbons that do not react with urea.

Application of Asphalt-aggregates Interfacial Energies to Evaluate Moisture-induced Damage of Warm Mix Asphalt  

Science Journals Connector (OSTI)

Abstract With increasing environmental awareness and high oil prices, use of warm mix asphalt (WMA) is gaining popularity in the asphalt industry. Different WMA technologies including use of additives to reduce the mixing and compaction temperatures are being applied. The present study uses the surface free energy (SFE) method as a mechanistic framework to evaluate the moisture susceptibility of warm mix asphalt (WMA) with Evotherm® WMA-additive. The SFE components of a modified PG64-22 asphalt binder with different percentages of Evotherm® and selected aggregates were measured in the laboratory. The work of adhesion, the work of debonding, and energy ratios were estimated to assess the moisture-induced damage potential of combinations of neat and Evotherm®-modified asphalt binders and different aggregates. The results indicated that use of Evotherm® resulted in increase in total SFE and work of adhesion and a reduction in the work of debonding, indicating a better possible aggregate-asphalt binder bond and lower moisture susceptibility potential. It is expected that the present study would be helpful in understanding the moisture-damage potential of flexible pavements constructed with WMA technologies.

Theoretical study on the lubrication failure for the lubricants with a limiting shear stress  

Science Journals Connector (OSTI)

It is observed that the non-slip boundary conditions in the classical lubrication theory are not valid for lubricant with a limiting shear stress. By determining the position of the maximum shear stress and changing velocity boundary condition to stress condition, slip lubrication equations are deduced. With numerical solution of the equations, the location and scale of the boundary slip are analyzed. Finally, after the influences of the slip on the lubrication properties are discussed, results show that a significant decrease of the load carrying capacity causes slip lubrication failure.

Evaluation of plastic–rubber asphalt: Engineering property and environmental concern  

Science Journals Connector (OSTI)

Abstract Waste rubber and plastic are accumulating heavily in China and causing significant environmental issues. In this study, the rubber and one kind of plastic, polypropylene (PP), were powdered and mixed with base asphalt to form plastic–rubber asphalt (PRA). This study evaluated PRA and the mixture in two-folds, engineering properties and environmental concerns. SBS asphalt, one commonly used asphalt binder in China, was adopted as a control. To evaluate the environmental burdens of PRA mixture and SBS asphalt mixture, a cradle-to-gate life cycle assessment (LCA) modeling was performed. Throughout the study, it is revealed that: (1) as a binder, PRA is weaker in terms of softening point, elastic recovery and fatigue performance versus SBS asphalt, but the differences are limited; (2) PRA mixture are close to SBS asphalt mixture for the high temperature, low temperature performances and water durability; (3) PRA mixture is more environmental-friendly compared to SBS asphalt mixture.

Use of a warm mix asphalt additive to reduce the production temperatures and to improve the performance of asphalt rubber mixtures  

Science Journals Connector (OSTI)

Asphalt rubber mixtures are often described as environmentally friendly mixtures due to the incorporation of recycled rubber from used tires and due to their improved service life. In fact, their fatigue cracking and rut resistance properties are better than those of conventional asphalt concrete mixtures. However, asphalt rubber mixtures demand higher production temperatures than conventional mixtures due to the higher viscosity of the asphalt rubber binder. The objective of this paper is to assess the efficiency of using a surfactant based additive in the production of warm mix asphalts, by lowering the mixing temperatures of asphalt rubber and asphalt concrete mixtures without changing their performance. Several laboratory tests were carried out on asphalt rubber and asphalt concrete mixtures, with and without the additive, in order to evaluate and compare the performance of the mixtures. It was concluded that the incorporation of small amounts of a surfactant based additive allowed reducing the production temperatures of both types of mixture by 30 °C without compromising their performance, and this can be seen as a great step forward towards the production of cleaner asphalt rubber mixtures.

Identification of tribological research and development needs for lubrication of advanced heat engines  

SciTech Connect

The continuous evolution of higher power density propulsion systems has always fueled the search for materials and lubricants with improved thermal and/or durability characteristics. Tribology of the upper cylinder region is the major technology roadblock in the path of the adiabatic diesel engine which has an energy reduction potential that exceeds that of all other engine development types. This tribology assessment resulted in the following major conclusions: a low friction and a low wear seal between the ring belt and cylinder bore are the most critical tribology functions in the diesel combustion chamber; development of solid lubrication systems will not satisfy the simultaneous low friction and low wear requirements in the upper cylinder area; development of separate upper cylinder liquid lubrication systems offers the most attractive design alternative for meeting the operational goals of future ''minimum cooled'' diesel engines.

Asphalt emulsion sealing of uranium mill tailings. 1980 annual report  

SciTech Connect

Studies of asphalt emulsion sealants conducted by the Pacific Northwest Laboratory have demonstrated that the sealants are effective in containing radon and other potentially hazardous material within uranium tailings. The laboratory and field studies have further demonstrated that radon exhalation from uranium tailings piles can be reduced by greater than 99% to near background levels. Field tests at the tailings pile in Grand Junction, Colorado, confirmed that an 8-cm admix seal containing 22 wt% asphalt could be effectively applied with a cold-mix paver. Other techniques were successfully tested, including a soil stabilizer and a hot, rubberized asphalt seal that was applied with a distributor truck. After the seals were applied and compacted, overburden was applied over the seal to protect the seal from ultraviolet degradation.

Elastohydrodynamic Lubrication with Polyolester Lubricants and HFC Refrigerants, Final Report, Volume 2  

SciTech Connect

Lubrication properties of refrigeration lubricants were investigated in high pressure nonconforming contacts under different conditions of temperature, rolling speed, and refrigerant concentration. The program was based upon the recognition that the lubrication regime in refrigeration compressors is generally elastohydrodynamic or hydrodynamic, as determined by the operating conditions of the compressor and the properties of the lubricant. Depending on the compressor design, elastohydrodynamic lubrication conditions exist in many rolling and sliding elements of refrigeration compressors such as roller element bearings, gears, and rotors. The formation of an elastohydrodynamic film separating rubbing surfaces is important in preventing the wear and failure of compressor elements. It is, therefore, important to predict the elastohydrodynamic (EHD) performance of lubricants under realistic tribocontact renditions. This is, however, difficult as the lubricant properties that control film formation are critically dependent upon pressure and shear, and cannot be evaluated using conventional laboratory instruments. In this study, the elastohydrodynamic behavior of refrigeration lubricants with and without the presence of refrigerants was investigated using the ultrathin film EHD interferometry technique. This technique enables very thin films, down to less than 5 nm, to be measured accurately within an EHD contact under realistic conditions of temperature, shear, and pressure. The technique was adapted to the study of lubricant refrigerant mixtures. Film thickness measurements were obtained on refrigeration lubricants as a function of speed, temperature, and refrigerant concentration. The effects of lubricant viscosity, temperature, rolling speed, and refrigerant concentration on EHD film formation were investigated. From the film thickness measurements, effective pressure-viscosity coefficients were calculated. The lubricants studied in this project included two naphthenic mineral oils (NMO), four polyolesters (POE), and two polyvinyl ether (PVE) fluids. These fluids represented viscosity grades of ISO 32 and ISO 68 and are shown in a table. Refrigerants studied included R-22, R-134a, and R-410A. Film thickness measurements were conducted at 23 C, 45 C, and 65 C with refrigerant concentrations ranging from zero to 60% by weight.

We have prepared some chlorofluoroethers for testing as additives for normal petroleum and polyalphaolefin lubricants which are so widely used in the United States. Perfluoropolyethers are not soluble in hydrocarbons. On the other hand, these chlorofluoropolyethers are soluble in substantial amounts in simple hydrocarbons. These are uniquely capable of being additives that flow with the motor oil or the polyalphaolefin.

Temperature–friction characteristics of used lubricant from two-stroke cross-head marine diesel engines  

Science Journals Connector (OSTI)

It is now quite apparent that, in a two-stroke, cross-head marine diesel engine, the lubrication regime in the contact between piston ring and cylinder liner at the top dead centre (TDC) is of a boundary type. Therefore, the tribological performance of a system to simulate the real contact should be assessed under conditions closely resembling the operating engine environment. In the reality of engine operation, the lubricant is often contaminated by fuel and products of combustion, hence the need to study the temperature–friction characteristics of this actual lubricant under the conditions of boundary lubrication. In this paper, an oil taken from the drainage system of the engine was used. A five times heating and cooling test methodology was employed to assess tribological performance of a model contact lubricated with the actual oil. The model contact was formed by a pin sliding over a plate both made of materials used in two-stroke, cross-head marine diesel engines. Experiments showed that the general trend in temperature–friction characteristics of the used oil is similar to that of a new oil. However, the level of friction in the contact lubricated with an used oil is significantly higher than that for a new oil.

Study of ice and snow melting process on conductive asphalt solar collector  

Science Journals Connector (OSTI)

This paper investigates the snow melting process on asphalt pavements as solar collector by experiments and numerical simulation. A numerical simulation method was used to predict the general design requirements for snow melting system of asphalt pavements, and a type of experimental asphalt snow melting system has been built using the design parameters obtained from the preceding simulation. Graphite powders were used to improve the thermal conductivity of asphalt concrete and thus resulting in an improved efficiency of asphalt collector. A laboratory snow melting test was performed after real snowstorm events. The effects of thermal conductive asphalt concrete (CAC) on snow melting performance and asphalt pavement temperature distribution were evaluated. The heat transfer in the asphalt slabs and the heat requirement for the snow melting were analyzed. The results that are obtained show that asphalt solar collector (ASC) provides us a better alternative method for snow melting. The higher fluid temperature is a positive way to improve the performance of snow melting system. However, it is unnecessary to keep a too high fluid temperature so as to reduce the waste of energy. The non-uniform temperatures in the asphalt slabs are noticeable. Furthermore, the heat-transmission and the snow melting performance can be enhanced using CAC.

Evaluation of western and eastern shale oil residua as asphalt pavement recycling agents  

SciTech Connect

The objective of this investigation was to perform a preliminary evaluation of the utility of residual materials prepared from Green River Formation (western) and New Albany Shale (eastern) shale oils as recycling agents for aged asphalt pavement. Four petroleum asphalts were first aged by a thin-film accelerated-aging test, which simulates long service life of asphalt in pavement. The aged asphalts were mixed (recycled) with Green River Formation shale oil distillation residua to restore the original viscosities. Separately, for comparison, a commercial recycling agent was used to recycle the aged asphalts under the same circumstances. The recycled asphalts were reaged and the properties of both binder and asphalt-aggregate mixtures studied. Originally, the same study was intended for an eastern shale residua. However, the eastern shale oil distillation residua with the required flash point specification also had the properties of a viscosity builder; therefore, it was studied as such with asphalts that do not achieve sufficient viscosity during processing to serve as usable binders. Results show that Green River Formation shale oil residuum can be used to restore the original asphalt properties with favorable rheological properties, the shale oil residuum has a beneficial effect on resistance to moisture damage, the low-temperature properties of the shale oil residuum recycled asphalts are not adversely affected, and the low-temperature properties of the shale oil residuum recycled asphalts are dependent upon the chemistry of the mixture. The eastern shale oil residua was blended with soft petroleum asphalts. Results show the products have higher viscosities than the starting materials, the rheological properties of the soft asphalt-eastern shale oil residue blends are acceptable, and the eastern shale oil residue has dispersant properties despite its high viscosity. 11 refs., 3 figs., 9 tabs.

Tribological behavior of some candidate advanced space lubricants  

SciTech Connect

Performance of a variety of space lubricants was compared under boundary and elastohydrodynamic lubrication (EHL). The types of fluids studied were naphthenic mineral oil, paraffinic mineral oil, polyalphaolefin, and silahydrocarbon. The silahydrocarbon and the polyalphaolefin lubricants exhibited lower traction under similar conditions. A specific additive package increased the traction of the polyalphaolefin. Volatility characteristics of some of these fluids were also studied. 10 refs.

Evaluation of moisture susceptibility of asphalt mixes containing RAP and different types of aggregates and asphalt binders using the surface free energy method  

Science Journals Connector (OSTI)

Abstract The surface free energy (SFE) measurement of asphalt binder and aggregate is considered a reliable mechanistic framework for evaluating the moisture-induced damage potential of asphalt mixes. In the present study, the SFE method was used to evaluate the effects of asphalt binder type, Reclaimed Asphalt Pavement (RAP) and its amount, and aggregate type on the moisture-induced damage potential of asphalt mixes. The SFE components (non-polar, acid and base) of a PG 64-22 and a PG 76-28 (polymer-modified) asphalt binders, blended with different amounts of RAP binder (0%, 10%, 25% and 40%) were measured in the laboratory using a Dynamic Contact Angle (DCA) analyzer. Also, the SFE components of six types of aggregates, namely limestone, rhyolite, sandstone, granite, gravel, and basalt were used in this study. The SFE components of limestone and rhyolite aggregates were measured using a Universal Sorption Device (USD), while those of the sandstone, granite, gravel, and basalt aggregates were obtained from the literature. The energy ratio parameters estimated based on the spreading coefficient, the work of adhesion, and the work of debonding were used to assess the moisture-induced damage potential of different combinations of asphalt binders and different RAP binder contents and aggregates. The SFE test results indicated that the acid SFE component of PG 64-22 and PG 76-28 asphalt binders increase with the addition of RAP binder, while the base SFE component remains almost unchanged. Also, the wettability and the work of adhesion of both PG 64-22 and PG 76-28 asphalt binders over different types of aggregates increased with an increase in RAP content (by 25% and more). Based on the energy ratio parameters, it was found that the resistance to moisture-induced damage increased with an increase in RAP content for both PG 64-22 and PG 76-28 asphalt binders and all types of aggregates, specifically when higher RAP contents were used. Moreover, it was found that the higher the total SFE of the aggregates, the lower the energy ratio parameter values. Therefore, a high total SFE component of aggregate may result in a high moisture-induced damage potential of the mix. The results presented herein are expected to be helpful in mechanistically assessing the moisture-induced damage potential of asphalt mixes, produced with polymer-modified and non-polymer-modified asphalt binders, containing RAP.

Evaluation of an eastern shale oil residue as an asphalt additive  

SciTech Connect

An evaluation of eastern shale oil (ESO) residue as an asphalt additive to reduce oxidative age hardening and moisture susceptibility was conducted by Western Research Institute (WRI). The ESO residue, have a viscosity of 23.9 Pa{lg_bullet}s at 60{degree}C (140{degree}F), was blended with three different petroleum-derived asphalts, ASD-1, AAK-1, and AAM-1, which are known to be very susceptible to oxidative aging. Rheological and infrared analyses of the unaged and aged asphalts and the blends were then conducted to evaluate oxidative age hardening. In addition, the petroleum-derived asphalts and the blends were coated onto three different aggregates, Lithonia granite (RA), a low-absorption limestone (RD), and a siliceous Gulf Coast gravel (RL), and compacted into briquettes. Successive freeze-thaw cycling was then conducted to evaluate the moisture susceptibility of the prepared briquettes. The rheological analyses of the unaged petroleum-derived asphalts and their respective blends indicate that the samples satisfy the rutting requirement. However, the aging indexes for the rolling thin film oven (RTFO)-aged and RTFO/pressure aging vessel (PAV)-aged samples indicate that the blends are stiffer than the petroleum-derived asphalts. This means that when in service the blends will be more prone to pavement embrittlement and fatigue cracking than the petroleum-derived asphalts. Infrared analyses were also conducted on the three petroleum-derived asphalts and the blends before and after RTFO/PAV aging. In general, upon RTFO/PAV aging, the amounts of carbonyls and sulfoxides in the samples increase, indicating that the addition of the ESO residue does not mitigate the chemical aging (oxidation) of the petroleum-derived asphalts. This information correlates with the rheological data and the aging indexes that were calculated for the petroleum-derived asphalts and the blends.

Biofiltration of asphalt emissions: Full-scale operation treating off-gases from polymer-modified asphalt production  

SciTech Connect

In response to complaints from nearby residents, a biofilter was designed, installed, and tested for treating odors in one of three odorous emission streams from an asphalt plant producing polymer-modified asphalt. Hydrogen sulfide (H{sub 2}S) was determined to be the most prevalent gaseous reduced sulfur compound and was detected in the emission stream only when polymer material was being added to raw asphalt. Emission stream H{sub 2}S concentrations were quite variable, ranging from 16 to approximately 30,000 ppm (v/v) and considered the likely compound contributing most to the plant's odor complaints. The biofilter was effective in controlling odor from the production process and removed an overall average of 65% of the H{sub 2}S during polymer addition, and for H{sub 2}S concentrations less than 400 ppmv, removal averaged 98%. These removal efficiencies reflect data from the biofilter operating at 2.5-minute empty bed residence time in 1996 and a 6.1-minute empty bed residence time in 1997. The biofilter's bed became increasingly acidified during the plant's 1997 operating season producing a pH gradient through the bed ranging from a high of 6.6 to a low of 3.1. The bed medium moisture content remained constant at about 60% (wet weight basis), but changes were observed in the water potential: no correlation to performance was determined. Changes in the microbial community reflected the bed acidification trend, with acidophiles becoming generally more numerous in the bed's deeper portions and in the mid to late season when the bed was most acidified. Bed acidification did not impact the biofilter's H{sub 2}S removal efficiency.

Rubber friction on (apparently) smooth lubricated surfaces  

E-Print Network (OSTI)

We study rubber sliding friction on hard lubricated surfaces. We show that even if the hard surface appears smooth to the naked eye, it may exhibit short wavelength roughness, which may give the dominant contribution to rubber friction. That is, the observed sliding friction is mainly due to the viscoelastic deformations of the rubber by the substrate surface asperities. The presented results are of great importance for rubber sealing and other rubber applications involving (apparently) smooth surfaces.

Emission stream H2S concentrations we requite variable, ranging from 16 to approximately 30,000 ppm (v/v) and considered the likely compound contributing most to the plant's odor complaints. The biofilter was effective in controlling odor from the production process and removed an overall average of 65% of the H2S during polymer addition, and for H2S concentrations less than 400 ppmv, re m oval averaged 98%. These removal efficiencies reflect data from the biofilter operating at 2.5-minute empty bed residence time in 1996 and a 6.1-minute empty bed residence time in 1997. The biofilter's bed became increasingly acidified during the plant's 1997 operating season producing a pH gradient through the bed ranging from a high of 6.6 to a low of 3.1. The bed medium moisture content remained constant at about 60% (wet weight basis), but changes were observed in the water potential: no correlation to performance was determined. Changes in the microbial community reflected the bed acidification trend, with acidophiles becoming gene rally more numerous in the bed's deeper portions and in the mid to late season when the bed was most acidified. Bed acidification did not impact the biofilter's H2S removal efficiency. Nearby residents we resurveyed and roughly half of the respondents indicated that the odor conditions had improved, one-third felt odor conditions were unchanged and the remaining 15% felt odor conditions were worse despite the fact that only one of three of the plant's odorous emission streams were treated by the biofilter. Plans are to implement biofiltration for odor control at all of the facility's emission points.

Rheological properties and chemical analysis of nanoclay and carbon microfiber modified asphalt with Fourier transform infrared spectroscopy  

Science Journals Connector (OSTI)

This work aims to improve the rutting and fatigue cracking resistance of asphalt binders using selected nano- or micro-sized materials and to shed light on the microstructure changes induced by such modification to asphalt binders. The four modifiers (Nanomer I.44P, carbon microfiber, non-modified nanoclay and polymer modified nanoclay) were added into the control asphalt binder (PG 58-34). The Superpave™ tests and Fourier transform infrared spectroscopy (FTIR) measurements were conducted for obtaining the complex shear modulus G* and microstructure distribution of modified asphalt binders. Meanwhile, the short-term and long-term aging processes of asphalt binders are simulated by rolling thin film oven (RTFO) and pressure aging vessel (PAV) tests. From the dynamic shear rheometer (DSR) and FTIR tests results, the complex shear modulus G* values of nano- or micro-materials (Nanomer I.44P, non-modified nanoclay and carbon microfiber) modified asphalt binders increase, and the performance of resistance to rutting is improved compared to the control asphalt binder. The addition of polymer modified nanoclay (PMN) into the control asphalt binder decreases the complex shear modulus, and enhances the resistance to fatigue cracking. Moreover, the addition of four modifiers into the control asphalt binder can delay and weaken the aging and oxidation effect.

State of the practice: Design and construction of asphalt paving materials with crumb-rubber modifier. Final report  

SciTech Connect

The document is a comprehensive overview of the terminology, processes, products, and applications of crumb rubber modifier (CRM) technology. The technology includes any use of scrap tire rubber in asphalt paving materials. In general, CRM technology can be divided into two categories--the wet process and the dry process. When CRM is incorporated into an asphalt paving material, it will modify the properties of the binder (asphalt rubber) and/or act as a rubber aggregate (rubber modified hot mix asphalt). The five concepts for using CRM discussed in the report are McDonald, PlusRide, generic dry, chunk rubber asphalt concrete, and continuous blending asphalt rubber. There are two principal unresolved engineering issues related to the use of CRM in asphalt paving materials. On the national level, the ability to recycle asphalt paving mixes containing CRM has not been demonstrated. At the State and local levels, these modified asphalt mixes must be field evaluated to establish expected levels of performance. The appendices provide guidelines for material specifications, mix design, and construction specifications. An experimental work plan for monitoring performance and a stack emission testing program are also included.

Making premium diesel fuel  

SciTech Connect

For refiners, extra processing and blending is a practical, though not always easy, option for improving diesel fuel properties; however, it entails compromises. For example, ignition quality can be improved by including more paraffins, but this negatively impacts the required low-temperature operability properties. Another example is adding aromatics to increase the diesel`s Btu value, but aromatics burn poorly and tend to cause smoking. Due to these and other types of diametrical trade-offs, the scope of distillate processing and fuels blending at the refinery is often very limited. Therefore, fuel additives are rapidly becoming the only alternative for obtaining the superior quality necessary in a premium diesel fuel. If stabilizers, dispersants and other fuel additive components are used in the additive package, the product can be marketed as a premium diesel fuel additive. Engines using this additive-treated fuel will consistently have less emissions, produce optimum power from the fuel energy conversion process and perform to design specifications. And the user will truly have a premium diesel fuel. The paper discusses detergent additives, cetane or ignition improvers, fuel stabilizers, cold weather additives, and lubricity additives.

Evaluation of an eastern shale oil residue as an asphalt additive  

SciTech Connect

An evaluation of eastern shale oil (ESO) residue as an asphalt additive to reduce oxidative age-hardening and moisture susceptibility was conducted. The ESO residue, having a viscosity of 23.9 Pa{sm_bullet}s at 60{degrees}C (140{degrees}F), was blended with three different petroleum-derived asphalts, AAD-1, AAK-1, and AAM-1, that are known to be very susceptible to oxidative aging. Rheological and infrared analyses of the unaged and aged asphalts and the blends were then conducted to evaluate oxidative age-hardening. In addition, the petroleum-derived asphalts and the blends were coated onto three different aggregates, Lithonia granite (RA), a low-absorption limestone (RD), and a silicious Gulf Coast gravel (RL), and compacted into briquets. Successive freeze-thaw cycling was then conducted to evaluate the moisture susceptibility of the prepared briquets. The abbreviations used above for the asphalts and the aggregates are part of the Strategic Highway Research Program nomenclature.

Chapter Five The Classification and Applications of Liquid Lubricants  

Science Journals Connector (OSTI)

Publisher Summary This chapter discusses the classification and applications of liquid lubricants. As a result of technical developments, currently many types of lubricating oils and special fluids exist. The technical needs are expressed in various commercial criteria used for oil classification. The type of equipment, and its component parts, defines the basis of the oil classification; the operating conditions of the lubricated part provide other important criteria needed to define the characteristics required in the oil. The main oil classifications in terms of equipment are into engine oils, turbine oil, steam turbine oils, etc. Oils for various parts of the equipment include bearing oils, transmission oils, hydraulic oils, etc. Another classification system deals with the special requirements of certain industrial sectors. Thus, for example, textile oils, electrical insulating oils, quenching oils and oils for application in radioactive environments are specially manufactured and classified. Two-stroke gasoline engines used for powering four- and two-wheeled road vehicles, small boats, mowers, etc., can be classified in the context of lubrication under two groups: (1) engines with conventional lubrication systems and (2) engines with separate lubrication systems.

Rotary seal with enhanced lubrication and contaminant flushing  

DOE Patents (OSTI)

A resilient, ring shaped interference-type hydrodynamic rotary seal having waves on the lubricant side which provide increased film thickness and flushing action by creating contact pressure induced angulated restrictions formed by abrupt restrictive diverters. The angulated restrictions are defined by projecting ridges, corners at the trailing edge of the waves, or simply by use of a converging shape at the trailing edge of the waves which is more abrupt than the gently converging hydrodynamic inlet shape at the leading edge of the waves. The abrupt restrictive diverter performs two functions; a restricting function and a diverting function. The angulated restrictions cause a local film thickness restriction which produces a damming effect preventing a portion of the lubricant from leaking out of the dynamic sealing interface at the trailing edge of the wave, and results in a much thicker lubricant film thickness under the waves. This contributes to more film thickness in the remainder of the dynamic sealing interface toward the environment because film thickness tends to decay gradually rather than abruptly due to the relative stiffness of the seal material. Because of the angle of the abrupt restrictive diverter relative to the relative rotation direction, in conjunction with the restriction or damming effect, a strong diverting action is produced which pumps lubricant across the dynamic sealing interface toward the environment. The lubricant diversion is caused by the component of the rotational velocity tangent to the abrupt restrictive diverter. The component of rotational velocity normal to the abrupt restrictive diverter causes a portion of the lubricant film to be pumped past the abrupt restrictive diverter, thereby assuring adequate lubrication thereof.

Performance of MOV Stem Lubricants at Elevated Temperatures  

SciTech Connect

This paper documents the results of recent tests sponsored by the U. S. Nuclear Regulatory Commission (NRC) and performed by the Idaho National Engineering and Environmental Laboratory (INEEL). These tests address the effectiveness of the lubricant used on the threaded portion of the valve stem, where the stem nut turns on the stem. Recent testing indicates that an elevated temperature environment can lead to significant increases in the friction coefficient at the stem/stem-nut interface. Most valve actuator qualification tests are performed at room temperature. Similarly, in-service tests are run at ambient plant temperatures, usually 70 to 100°F. Since design conditions can lead to valve operating temperatures in the 200 to 300°F range, it is important to know whether a temperature-induced increase in friction at the stem/stem-nut interface will prevent the required operation of critical valves. Lubricant aging is another phenomenon that might have deleterious effects on the thrust output of a valve actuator. Laboratory experience and field experience both indicate that after long periods in elevated temperature environments, the lubricants may lose their lubrication qualities. The scope of the current test program includes testing of five different lubricants on four different valve stems. Pending completion of the testing, results of the tests conducted using two of the four stems are discussed. The test series included collection of baseline data at room temperature, single step temperature tests where the temperature of the test setup was elevated directly to 250°F, and step testing where the temperature was elevated in steps to 130, 190, and 250°F, then returned to 70°F. All greases tested showed evidence of physical change after elevated temperature tests. Except for one particular lubricant, all of the greases tested showed increased coefficients of friction at elevated temperatures. Numerous other preliminary conclusions are presented. Recommendations for future research in the area of aged valve stem lubricant performance at elevated temperatures are also presented.

Life-cycle assessment (LCA) is utilised for evaluation of the environmental impacts of energy and material flows throughout the product life. Several comprehensive \\{LCAs\\} have compared mineral oil-based and bio-based lubricants, reporting varying conclusions. Environmental savings of biolubricants are more apparent at a local level than at a global scale. Negative impacts mainly stem from their agricultural production and performance in the use phase. \\{LCAs\\} should be used in industrial product design of biolubricants. Sustainable development indicators also consider the socio-economic impact of a product. Optimised lubricants determine significant energy savings.

Use of Textured Surfaces to Mitigate Sliding Friction and Wear of Lubricated and Non-Lubricated Contacts  

SciTech Connect

If properly employed, the placement of three-dimensional feature patterns, also referred to as textures, on relatively-moving, load-bearing surfaces can be beneficial to their friction and wear characteristics. For example, geometric patterns can function as lubricant supply channels or depressions in which to trap debris. They can also alter lubricant flow in a manner that produces thicker load-bearing films locally. Considering the area occupied by solid areas and spaces, textures also change the load distribution on surfaces. At least ten different attributes of textures can be specified, and their combinations offer wide latitude in surface engineering. By employing directional machining and grinding procedures, texturing has been used on bearings and seals for well over a half century, and the size scales of texturing vary widely. This report summarizes past work on the texturing of load-bearing surfaces, including past research on laser surface dimpling of ceramics done at ORNL. Textured surfaces generally show most pronounced effects when they are used in conformal or nearly conformal contacts, like that in face seals. Combining textures with other forms of surface modification and lubrication methods can offer additional benefits in surface engineering for tribology. As the literature and past work at ORNL shows, texturing does not always provide benefits. Rather, the selected pattern and arrangement of features must be matched to characteristics of the proposed application, bearing materials, and lubricants.

Gas film lubrication equations for very small clearances  

SciTech Connect

In the hard disk magnetic recording technology, the slider carrying the magnetic elements is supported above the magnetic disk by a self-acting air bearing, which produces the load support. A lubricating film must support a required load with suitably small frictional energy losses and without introducing undesirable instabilities. Under submicron clearance conditions, gas film flow can not be described with continuum models since the molecular mean free path is not negligible compared with the clearance. Accurate results for the load-carrying capacity of gas films for arbitrary Knudsen number are very important since they strongly influence the design of the flying head slider and, consequently, the performance of the magnetic disk storage unit. Here we generalize the previous lubrication equations for arbitrary Knudsen number, accommodation coefficient and a small inclination of the slider relative to the magnetic disk surface.

A novel system to study wear, friction, and lubricants  

SciTech Connect

A novel enclosed (pressurized) multispecimen wear testing system was design and built to allow the fully computerized on-line measurement and control of friction, wear, and lubricants of different materials (metals, ceramics, composites, and plastics). This system is described in detail. The tribological parameters can be adjusted and controlled to reproduce the actual conditions that prevail in machine components. Several examples of the capabilities of the system are presented.

Development of asphalts and pavements using recycled tire rubber. Phase 1, Technical feasibility. Technical progress report, September 1, 1994--August 31, 1995  

SciTech Connect

About 285 million tires are discarded every year; less than 100 million are currently being recycled, with the rest being placed in landfills and other waste sites. A solution to reduce the littering of the environment is to use ground tire rubber in road construction. Currently, about 27 million tons of asphalt are used each year in road construction and maintenance of the country`s 2 million miles of roads. If all of the waste tire rubber could be combined with asphalt in road construction, it would displace less than 6% of the total asphalt used each year, yet could save about 60 trillion Btus annually. Purpose of this project is to provide data needed to optimize the performance of rubber-asphalt concretes. The first phase is to develop asphalts and recycling agents tailored for compatibility with ground tire rubber. Chapter 2 presents results on Laboratory Testing and Evaluation: fractionate asphalt material, reblending for aromatic asphalts, verifying optimal curing parameters, aging of blends, and measuring ductilities of asphalt-rubber binders. Chapter 3 focuses on Evaluating Mixture Characteristics (modified binders). Chapter 4 covers Adhesion Test Development (water susceptibility is also covered). The final chapter focuses on the Performance/Economic Update and Commercialization Plan.

Solid/liquid lubrication of ceramics at elevated temperatures  

SciTech Connect

This study investigates the effect of solid and liquid lubrication on friction and wear performance of silicon nitride (Si{sub 3}N{sub 4}) and cast iron. The solid lubricant was a thin silver film ({approx}2 {mu}m thick) produced on Si{sub 3}N{sub 4} by ion-beam-assisted deposition. A high-temperature polyol-ester-base synthetic oil served as the liquid lubricant. Friction and wear tests were performed with pin-on-disk and oscillating-slider wear test machines at temperatures up to 300{degrees}C. Without the silver films, the friction coefficients of Si{sub 3}N{sub 4}/Si{sub 3}N{sub 4} test pairs were 0.05 to 0.14, and the average wear rates of Si{sub 3}N{sub 4} pins were {approx}5 x 10{sup -8} mm{sup 3} N{sup -1}. The friction coefficients of Si{sub 3}N{sub 4}/cast iron test pairs ranged from 0.08 to 0.11, depending on test temperature. The average specific wear rates of cast iron pins were {approx}3 x 10{sup -7} mm{sup 3} N{sup -1} m{sup -1}. However, simultaneous use of the solid-lubricant silver and synthetic oil on the sliding surfaces reduced friction coefficients to 0.02 to 0.08. Moreover, the wear of Si{sub 3}N{sub 4} pins and silver-coated Si{sub 3}N{sub 4} disks was so low that it was difficult to assess by a surface profilometer. The wear rates of cast iron pins were {approx}7 x 10{sup -9} mm{sup 3} N{sup -1} m{sup -1} up to 250{degrees}C, but showed a tendency to increase slightly at much higher temperatures. In general, the test results demonstrated that the solid/liquid lubrication of ceramic and/or metallic components is both feasible and effective in controlling friction and wear.

Traditional and Dissipated Energy approaches to compare the 2PB and 4PB flexural methodologies on a Warm Mix Asphalt  

Science Journals Connector (OSTI)

Abstract Two and four point bending tests are among the most common methodologies adopted for the fatigue characterization of asphalt mixes. Constraints and volumes of material are the main differences between these two testing procedures. This work presents the fatigue results from a warm asphalt mixture obtained with an innovative two point bending (2PB) apparatus and a traditional four point bending (4PB) one. The Dissipated Energy approach, based on the energy balance theory, as well as the traditional approach were chosen for the analysis. Finally, the influence of specimen volume on fatigue was assessed performing tests on specimens of different thicknesses.

Mutual changes in bitumen and rubber related to the production of asphalt rubber binders  

Science Journals Connector (OSTI)

Asphalt rubber (AR) mixtures are currently a material with an increasing use in road pavements due to their improved performance and environmental benefit of recycling rubber from used tires. AR binders have been widely applied, but the bitumen and rubber interactions remain poorly understood. The aim of this work is to quantify and correlate the changes in bitumen and rubber during AR binders’ production, in order to characterize the interactions between the AR constituent materials, e.g. residual bitumen and recovered rubber. A good correlation between the rheological and physical changes in the properties of rubber, bitumen and AR binder was observed.

Spring-supported thrust bearings used in hydroelectric generators: Limit ofhydrodynamic lubrication  

Science Journals Connector (OSTI)

The fluid film breakdown in large spring-supported thrust bearings was examined experimentally for low rotor speeds. Under these conditions, the lubrication was hydrodynamic rather than thermohydrodynamic and thus, the limit of hydrodynamic lubrication was sought. A thrust bearing test facility was used to test three bearings with various loads, speeds, and lubricant viscosities. Power loss and oil temperatures were measured and, using elementary theory, these measured quantities were linked to friction and average fluid film thickness in the bearing. A dimensionless performance number was developed and correlated with the coefficient of friction based on the power loss measurements. The breakdown of fluid film lubrication at the limit of hydrodynamic lubrication was established for an average performance number. The accuracy of the experimental findings was explored by comparing the friction and film thickness calculated from the measurements with the predictions of a comprehensive software package. Some general agreement was obtained. The relationship between the lambda ratio and a modified performance number was also examined based on typical surface roughness measurements. Although the procedures developed did not provide a high level of precision, some clear insights were gained into the thrust bearing behaviour at the limit of hydrodynamic lubrication. In particular, a large spring-supported thrust bearing under a typical load with a common lubricant was shown to sustain predominantly hydrodynamic lubrication at rotational speeds as low as 10 rpm.

6 - Nanoclay-modified asphalt mixtures for eco-efficient construction  

Science Journals Connector (OSTI)

Abstract: Polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number of physical properties are successfully enhanced when a polymer is modified with small amount of nanoclay on condition that the clay is dispersed at nanoscopic level. In this research, comparative rheological tests on binders and mechanical tests on asphalt mixtures containing unmodified and nanoclay modified bitumen were carried out. Two types of nanoclay were used: Nanofill-15 and Cloisite-15A. Rheological tests on binder were penetration, softening point, ductility and aging effect. Mechanical tests on asphalt mixture were Marshall stability, indirect tensile strength, resilient modulus, diametric fatigue and dynamic creep tests. Test results show that nanoclay can improve properties such as stability, resilient modulus and indirect tensile strength and result in superior performance compared to that of unmodified bitumen under dynamic creep. Nanoclays do not seem to have beneficial effects on fatigue behaviour at low temperatures. Optimum binder content and void in total mixture (VTM) increase by adding nanoclay to bitumen.

Waste lubricating oil: an annotated review. 1982 revision  

SciTech Connect

Because of renewed interest in waste oil, both in terms of energy conservation and as a threat to the environment, there appears to be a need for a systemic compilation of information on the subject. This is a revision of the 1979 manuscript (BETC/IC-79/4) reflecting publications of the last three years as well as incorporation of papers that were overlooked. The number of citations has jumped from 486 to 1203, with all previous citations also listed here. The bibliography is divided into broad subject areas. The Introduction gives the history and development of the used oil reclamation industry. The General section includes the comprehensive papers that address several subjects and thus, give a capsulated overview of the used oil situation. Sources of Information and Statistical Treatments of Data tell how to obtain additional and future information and data relating to waste oil and could aid those persons interested in keeping their knowledge current. The Other Lubricating Oils section covers many of the lubricants that have the potential for recycling. The Other Oils section is divided into four sub-sections to aid the reader to find the subject of interest. The section on Related Subjects includes those sideline areas that could apply to used oil reclamation.

Recycling of Flue Gas Desulfurization residues in gneiss based hot mix asphalt: Materials characterization and performances evaluation  

Science Journals Connector (OSTI)

Abstract On the one hand, huge amount of Flue Gas Desulfurization (FGD) residues, produced during scrubbing flue gas, is discarded as solid waste. Such solid waste would cause serious environmental problems. One the other hand, high quality aggregates, such as limestone and basalt, are running out due to the rapid development of highway construction. Ungraded aggregates such as gneiss are therefore considered in China to replace the high quality aggregates. The application of FGD residues as a filler in gneiss based asphalt mixture has benefits both in environmental and economic sides. The main objective of this research was to visualize the raw materials characterization and evaluate the effect of FGD residues on the performance of gneiss based asphalt mixture. X-ray diffraction (XRD), X-ray fluorescence (XRF), Scanning Electron Microscope (SEM), Differential Scanning Calorimetric & Thermal gravimetric (DSC–TG) were used to investigate the features of raw materials. The performance of gneiss based asphalt mixture including high-temperature deformation resistance, low-temperature crack resistance and moisture-induced damage resistance were evaluated. Dynamic creep test, three-point bending test, Retained Marshall Stability (RMS), Tensile Strength Ratio (TSR), Indirect Tensile (IDT) strength and Resilient Modulus (MR) test were conducted and analyzed. Dissipated Creep Strain Energy to fracture (DCSEf) ratio, fracture energy and model analysis were also used to evaluate moisture resistance, crack resistance and deformation resistance of asphalt mixture respectively. Research results indicate that FGD residues can partly improve the moisture resistance and crack resistance of gneiss asphalt mixture, while it might worse the high-temperature deformation resistance.

High temperature solid lubricant materials for heavy duty and advanced heat engines  

SciTech Connect

Advanced engine designs incorporate higher mechanical and thermal loading to achieve efficiency improvements. This approach often leads to higher operating temperatures of critical sliding elements (e.g. piston ring/cylinder wall contacts and valve guides) which compromise the use of conventional and even advanced synthetic liquid lubricants. For these applications solid lubricants must be considered. Several novel solid lubricant composites and coatings designated PS/PM200 have been employed to dry and marginally oil lubricated contacts in advanced heat engines. These applications include cylinder kits of heavy duty diesels, and high temperature sterling engines, sidewall seals of rotary engines and various exhaust valve and exhaust component applications. The following paper describes the tribological and thermophysical properties of these tribomaterials and reviews the results of applying them to engine applications. Other potential tribological materials and applications are also discussed with particular emphasis to heavy duty and advanced heat engines.

Determination of properties of PVE lubricants with HFC refrigerants[PolyVinylEther  

SciTech Connect

Polyalkyleneglycol (PAG) and polyol ester (POE) have been developed as refrigeration lubricants, used with HFC134a. PAG is used for automotive air conditioning systems and POE is used for domestic reciprocating refrigerators and for A/C systems. Although PAG exhibits good lubricity performance, it is difficult to use for domestic reciprocating refrigerators due to its low dielectric property. POE is difficult to use for automotive A/C systems, due to hydrolysis and poor lubricity performance. Polyvinylether (PVE) can be used in place of PAG and POE with HFC refrigerants. PVE is used for A/C systems as well as refrigerator and freezer applications. PVE is an ideal lubricant for use with HFCs.

Laser-induced short time scale thermal chemistry of perfluoropolyether lubricant films  

SciTech Connect

The authors investigate the effect of heating a perfluoropolyether lubricant film in a localized area for relatively short time periods using laser irradiation versus conventional oven heating. These experiments help provide understanding on how flash temperatures generated at frictional contacts affect the thermal chemistry of lubricant films. In these experiments, a CO{sub 2} laser heats a 50 {micro}m wide area of a silicon wafer for time periods ranging from 0.1 to 60 s. The surface temperature within the heated area (up to 280 C in these experiments) is monitored with a second laser by measuring the change in reflectivity near the center of the heated area. A major difference observed for laser heating compared to oven heating is that the effective evaporation rate is orders of magnitude higher for laser heating. If the lubricant film is heated for sufficiently long enough time at high temperatures, the authors are able to observe thermal bonding of the lubricant via its alcohol end groups to the silicon oxide surface, followed by thermal decomposition of the lubricant molecules. After laser heating, the authors are able to observe the diffusion of lubricant back into the localized heated area using a combination of optical microscopy and imaging ellipsometry.

Ionic Liquids as Novel Lubricants and Additives for Diesel Engine Applications  

SciTech Connect

The lubricating properties of two ionic liquids with the same anion but different cations, one ammonium IL [C8H17]3NH.Tf2N and one imidazolium IL C10mim.Tf2N, were evaluated both in neat form and as oil additives. Experiments were conducted using a standardized reciprocating sliding test using a segment of a Cr-plated diesel engine piston ring against a grey cast iron flat specimen with simulated honing marks as on the engine cylinder liner. The selected ionic liquids were benchmarked against conventional hydrocarbon oils. Substantial friction and wear reductions, up to 55% and 34%, respectively, were achieved for the neat ionic liquids compared to a fully-formulated 15W40 engine oil. Adding 5 vol% ILs into mineral oil has demonstrated significant improvement in the lubricity. One blend even outperformed the 15W40 engine oil with 9% lower friction and 34% less wear. Lubrication regime modeling, worn surface morphology examination, and surface chemical analysis were conducted to help understand the lubricating mechanisms for ionic liquids. Results suggest great potential for using ionic liquids as base lubricants or lubricant additives for diesel engine applications.

The importance of the use phase on the LCA of environmentally friendly solutions for asphalt road pavements  

Science Journals Connector (OSTI)

Abstract In order to assess sustainability of products and processes, different methodologies have been developed and used in the last years. In the road pavement construction area, most methodologies used for Life Cycle Assessment (LCA) are essentially focused in the construction phase. The present paper analyses the importance of the use phase of a road in the LCA of different paving alternatives, namely by evaluating energy consumption and gaseous emissions throughout the road pavement’s life. Therefore, a new LCA methodology for road pavements was developed, and the results of its application to a case study involving the construction of alternative pavement structures are discussed. The study intends to assess the influence of using more sustainable paving construction alternatives (asphalt recycling vs. conventional asphalt mixtures), and/or different surface course materials (which have a higher influence on the rolling resistance and, therefore, affect the performance during the use phase). The LCA results obtained for this case study showed that the reductions in energy consumption and gaseous emissions obtained during the use phase, for pavement alternatives with a lower rolling resistance surface course, are higher than the total amount of energy consumption and gas emissions produced during construction. It is therefore clear that some improvements in the characteristics of the surface course may have an effect over the road use phase that will rapidly balance the initial costs and gas emissions of those interventions. The LCA results obtained also showed that the sustainability of pavement construction may also be improved using recycled asphalt mixtures.

Performance and emissions of a diesel tractor engine fueled with marine diesel and soybean methyl ester  

Science Journals Connector (OSTI)

Biodiesel is an alternative fuel that is cleaner than petrodiesel. Biodiesel can be used directly as fuel for a diesel engine without having to modify the engine system. It has the major advantages of having high biodegradability, excellent lubricity and no sulfur content. This paper presents the results of investigations carried out in studying the fuel properties of soybean methyl ester (SME) and its blend with marine diesel fuel from 5%, 20% and 50% blends by volume and in running a diesel engine with these fuels. The results indicate that the use of biodiesel produces lower smoke opacity (up to 74%), but higher brake specific fuel consumption (BSFC) (up to 12%) compared to marine fuel (MF). The measured carbon monoxide (CO) emissions of B5 and B100 fuels were found to be 3% and 52% lower than that of the MF, respectively.

Process for producing a corrosion-resistant solid lubricant coating  

SciTech Connect

A corrosion-resistant surface formed of a sulfide-forming metal, in particular nickel, is first subjected to an electric plasma in an atmosphere containing hydrogen sulfide to form an adherent sulfide on said surface. The sulfided surface is then exposed to simultaneous cathodic sputtering of at least one solid lubricant which is a chalcogen compound of layer structure, in particular MoS/sub 2/, and at least one hydrophobic solid polymer, in particular PTFE. The coating thus formed is a composite coating in which the particles of the chalcogen compound are coated by the polymer. When the surface of the part to be coated does not consist of a corrosion-resistant sulfide-forming metal, a layer of such a metal is first deposited by cathodic sputtering. The composite coating withstands a wet oxidizing atmosphere, contrary to a coating of MoS/sub 2/ alone, and the method is applicable to any mechanical part intended to rub on other surfaces, such as a watch balance wheel staff and ball or roller bearings.

Combustion characteristics of dry coal-powder-fueled adiabatic diesel engine: Final report  

SciTech Connect

This report describes the progress and findings of a research program aimed at investigating the combustion characteristics of dry coal powder fueled diesel engine. During this program, significant achievements were made in overcoming many problems facing the coal-powder-fueled engine. The Thermal Ignition Combustion System (TICS) concept was used to enhance the combustion of coal powder fuel. The major coal-fueled engine test results and accomplishments are as follows: design, fabrication and engine testing of improved coal feed system for fumigation of coal powder to the intake air; design, fabrication and engine testing of the TICS chamber made from a superalloy material (Hastelloy X); design, fabrication and engine testing of wear resistant chrome oxide ceramic coated piston rings and cylinder liner; lubrication system was improved to separate coal particles from the contaminated lubricating oil; control of the ignition timing of fumigated coal powder by utilizing exhaust gas recirculation (EGR) and variable TICS chamber temperature; coal-fueled engine testing was conducted in two configurations: dual fuel (with diesel pilot) and 100% coal-fueled engine without diesel pilot or heated intake air; cold starting of the 100% coal-powder-fueled engine with a glow plug; and coal-fueled-engine was operated from 800 to 1800 rpm speed and idle to full load engine conditions.

XPS analysis of 440C steel surfaces lubricated with perfluoropolyethers under sliding conditions in high vacuum  

SciTech Connect

This work presents the results of the X-Ray Photoelectron Spectroscopy (XPS) analysis of AISI 440C ball surfaces lubricated with perfluoropolyether (PFPE) oils after friction experiments under sliding conditions at high load in air and vacuum environments. The PFPE lubricants tested were Demnum S100, Fomblin Z-25, and Krytox 143AB. It was found that all the PFPE lubricants were degraded by sliding contact causing the formation of inorganic fluorides on the metallic surfaces and a layer of organic decomposition products. KRYTOX 143AB was the least reactive of the three lubricants tested. It was also found that metal fluoride formed at off-scar areas. This suggests the formation of reactive species, such as COF2 or R[sub f]COF, during sliding experiments, which can diffuse through the lubricant film and react with the metallic surfaces away from the contact region. Comparison of reference specimens before sliding with those that had undergone the sliding tests showed that the amount of non-degraded PFPE remaining on the surface of the balls after the sliding experiments was greater than that of the balls without sliding.

Miscibility, solubility, and viscosity measurements for R-236EA with potential lubricants. Final report, October 1992-March 1995  

SciTech Connect

The report gives results of miscibility, solubility, and viscosity measurements of refrigerant R-236ea with three potential lubricants. The lubricants were a mineral oil, alkylbenzene, and polyol ester, each with a nominal viscosity of 68 cSt. The miscibility tests were performed in a test facility consisting of a series of miniature test cells in a constant-temperature bath. Critical solution temperatures obtained from the miscibility data are presented for each refrigerant/lubricant combination. In addition to miscibility data, both solubility and viscosity data were obtained for R-236ea and the most promising lubricant. For comparison purposes, data were also taken for the existing U.S. Navy shipboard chiller refrigerant and lubricant concentration, namely 4-114 and a naphthenic oil.

Development of high temperature liquid lubricants for low-heat rejection heavy duty diesel engines  

SciTech Connect

Objective was to develop a liquid lubricant that will allow advanced diesel engines to operate at top ring reversal temperatures approaching 500 C and lubricant sump temperatures approaching 250 C. Base stock screening showed that aromatic esters and diesters has the lowest deposit level, compared to polyol esters, poly-alpha-olefins, or refined mineral oil of comparable viscosity. Classical aryl and alkyl ZDP antiwear additives are ineffective in reducing wear with aromatic esters; the phosphate ester was a much better antiwear additive, and polyol esters are more amenable to ZDP treatment. Zeolites and clays were evaluated for filtration.

Improved surface adhesion and coverage of perfluoropolyether lubricants following far-UV irradiation  

SciTech Connect

Far-UV treatment of a surface with a thin film of a perfluoropolyether improves adhesion and lowers surface free energy substantially compared to the unirradiated, lubricated surface. With 185-nm radiation, approximately one monolayer can be fixed to surfaces such as amorphous carbon, silica, and gold. These lubricated surfaces become extremely hydrophobic after UV treatment (advancing water contact angle increases about 65{degree} to {ge} 110{degree}) and are not removed by fluorinated solvents. In the absence of far-UV radiation, most perfluoropolyethers show poor adhesion to carbon and are removed easily by rinsing with fluorinated solvents.

In situ measurement of the bonded film thickness of Z-Tetraol lubricant on magnetic recording media  

SciTech Connect

Currently, the bonded film thickness of perfluoropolyether lubricant on top of magnetic recording media is measured by a two-step process. First, the media disk has to be rinsed thoroughly using a fluorocarbon solvent (for instance, Vetrel) to remove the mobile lubricant. Second, the thickness of the remaining lubricant on the media surface which is regarded as the bonded lubricant thickness is then measured either by Fourier transform infrared spectroscopy (FTIR) or electron spectroscopy for chemical analysis. As the total lubricant thickness approaches single molecular dimension ({approx}10 A), current methods face tremendous challenge on the accuracy and sensitivity of the measurement. We studied the spectral characteristics responding to the lubricant bonding with the carbon overcoat by the time-of-flight secondary ion mass spectra and proposed to use the peak area ratio (C{sub 3}H{sub 2}F/C{sub 3}H{sub 5}O and C{sub 4}H{sub 10}O/C{sub 3}H{sub 6}O{sub 2}) to characterize the bonded Z-Tetraol lubricant that produces a direct bonded lubricant thickness measurement without the need to remove the mobile lubricant with a solvent. After taking the background signal of disks prior to bonding by UV irradiation into account, this method becomes independent of the total lubricant thickness as well as shows good correlation linearity (R{sup 2{approx}}87%) with the current FTIR method for the ratio of C{sub 4}H{sub 10}O/C{sub 3}H{sub 6}O{sub 2}.

Straight Vegetable Oil as a Diesel Fuel? Vehicle Technologies Program (VTP) (Fact Sheet)  

Alternative Fuels and Advanced Vehicles Data Center (EERE)

Performance of SVO Performance of SVO While straight vegetable oil or mixtures of SVO and diesel fuel have been used by some over the years, research has shown that SVO has technical issues that pose barriers to widespread acceptance. The published engineering literature strongly indicates that the use of SVO will lead to reduced engine life. This reduced engine life is caused by the buildup of carbon deposits inside the engine, as well as negative impacts of SVO on the engine lubricant. Both carbon deposits and excessive buildup of SVO in the lubricant are caused by the very high boiling point and viscosity of SVO relative to the required boiling range for diesel fuel. The carbon buildup doesn't necessarily happen quickly but instead over a longer period. These conclusions are

Tribological performance of NFC coatings under oil lubrication[Near Frictionless Carbon  

SciTech Connect

An increase in engine and vehicle efficiency usually requires an increase in the severity of contact at the interfaces of many critical components. Examples of such components include piston rings and cylinder liners in the engine, gears in the transmission and axle, bearings, etc. These components are oil-lubricated and require enhancement of their tribological performance. Argonne National Laboratory (ANL) recently developed a carbon-based coating with very low friction and wear properties. These near-frictionless-carbon (NFC) coatings have potential for application in various engine components for performance enhancement. This paper presents the study of the tribological performance of NFC-coated steel surfaces when lubricated with fully formulated and basestock synthetic oils. The NFC coatings reduced both the friction and wear of lubricated steel surfaces. The effect of the coating was much more pronounced in tests with basestock oil. This suggests that NFC-coated parts may not require heavily formulated lubricant oils to perform satisfactorily in terms of reliability and durability.

Tribological characteristics of aluminum alloys against steel lubricated by ammonium and imidazolium ionic liquids  

SciTech Connect

Sliding friction and wear characteristics of aluminum alloys against AISI 52100 steel lubricated by ionic liquids (ILs) were investigated at both room and elevated temperatures. The tested aluminum alloys include a commercially pure aluminum Al 1100, a wrought alloy Al 6061-T6511, and a cast alloy Al 319-T6. The lubricating performance of two ILs with the same anion, one ammonium-based [C8H17]3NH.Tf2N and one imidazolium-based C10mim.Tf2N, were compared each other and benchmarked against that of a conventional fully-formulated engine oil. Significant friction (up to 35%) and wear (up to 55%) reductions were achieved by the ammonium IL when lubricating the three aluminum alloys compared to the engine oil. The imidazolium IL performed better than the oil but not as well as the ammonium IL for Al 1100 and 319 alloys. However, accelerated wear was unexpectedly observed for Al 6061 alloy when lubricated by C10mim.Tf2N. Surface chemical analyses implied complex tribochemical reactions between the aluminum surfaces and ILs during the wear testing, which has been demonstrated either beneficial by forming a protective boundary film or detrimental by causing severe tribo-corrosion. The effects of the IL cation structure, aluminum alloy composition, and tribo-testing condition on the friction and wear results have been discussed.

A study on lubricant oil supply for positive-displacement expanders in small-scale organic Rankine cycles  

Science Journals Connector (OSTI)

Abstract Positive-displacement expanders, which are widely used in small-scale \\{ORCs\\} (Organic Rankine Cycles), need reliable LOS (Lubricant Oil Supply) to get well lubrication and sealing. In the present paper, the characteristics of two traditional LOS schemes are examined. Moreover, a modified one is proposed. Analyses of those elements that lead to work loss of lubricant oil supply have been carried out for all the three LOS schemes. The work loss of lubricant oil supply, which is caused by the employment of lubricant oil pumps, pressure drop in lubricant oil separator and other components contributing to work loss, is evaluated by a definition of WLLS (Work Loss Factor of Lubrication Oil Supply). Based on the thermodynamic model of ORC established, the calculation methods of WLLS are presented. Through analyses of LOS schemes and calculation of WLLS in two typical ORCs, it was found that the traditional LOS schemes either can not work reliably, or might cause up to 11.5% and 9.5% power decrease. The values can be reduced by half in the proposed LOS scheme, which can also work reliably. Accompanied with the advantages, the defects of the new scheme were also investigated.

Combustion characteristics of coal fuels in adiabatic diesel engines  

SciTech Connect

An experimental investigation was conducted to determine the combustion characteristics of coal fuels in adiabatic diesel engines. For this purpose engine testing was carried out by the fumigation of fine coal powder to the intake of an insulated and uncooled single cylinder diesel engine. The engine tests conducted include three types of fuels - Diesel fuel No. 2 (DF-2), Dual fuel (DF-2 + Coal), and Coal fuel. Excellent combustion characteristics of coal fuels were obtained in the present work in an adiabatic engine operating at high temperatures. The ''thermal ignition'' concept uncovered in this investigation led to a hot ''ignition chamber'' which provided ignition of the coal fuel. The high temperature engine with the ''ignition chamber'' permitted engine operation on 100% coal fuel without any external ignition aids or compression ignition. With the addition of a glow plug, the coal fueled engine was successfully cold started. For the coal fueled engine tests, analysis of cylinder pressure data showed rapid heat release rates, shorter combustion duration and very fast burning of coal powder fuel. Preliminary results of the apparent indicated cycle efficiency calculated from the heat release data, indicate that 100% coal powder fueled engine has higher cycle efficiency than DF-2 fueled engine in an adiabatic configuration. The problems encountered during the engine tests include: variation in the engine speed and load due to non-uniform coal flow rate by the coal feed system, contamination of the lubricating oil with fine coal powder, and wear of conventional piston rings. However, these problems can be solved with an improved coal feed system and wear resistant ceramic materials for the piston rings. 33 refs.

A review of lubrication and preformance issues in refrigeration systems using an HFC (R-134a) refrigerant  

SciTech Connect

It has been considered critical for refrigerant and compressor lubricant to be miscible with each other over part of the range of operating conditions of refrigerant systems. Adequate miscibility, many believe, provides oil return to the compressor. Presently, synthetic polyol esters have been selected for use with HFC refrigerants, such as R-134a, which are considered appropriate alternatives to CFCs. The authors will review the mechanical issues in miscible vs non-miscible naphthenic hydrocarbon oil-based lubricants. Extensive lab, test stand and cabinet testing has been conducted and data will be presented which show responsible and predictable performance based on the chemical and physical properties of the lubricant and refrigerant. Many non-miscible systems show satisfactory performance with the proper selection of lubricant, additives and mechanical configuration. 3 refs., 3 figs., 5 tabs.

DIMETHYL ETHER (DME)-FUELED SHUTTLE BUS DEMONSTRATION PROJECT  

SciTech Connect

The objectives of this research and demonstration program are to convert a campus shuttle bus to operation on dimethyl ether, a potential ultra-clean alternative diesel fuel. To accomplish this objective, this project includes laboratory evaluation of a fuel conversion strategy, as well as, field demonstration of the DME-fueled shuttle bus. Since DME is a fuel with no lubricity (i.e., it does not possess the lubricating quality of diesel fuel), conventional fuel delivery and fuel injection systems are not compatible with dimethyl ether. Therefore, to operate a diesel engine on DME one must develop a fuel-tolerant injection system, or find a way to provide the necessary lubricity to the DME. In this project, they have chosen the latter strategy in order to achieve the objective with minimal need to modify the engine. Their strategy is to blend DME with diesel fuel, to obtain the necessary lubricity to protect the fuel injection system and to achieve low emissions. The bulk of the efforts over the past year were focused on the conversion of the campus shuttle bus. This process, started in August 2001, took until April 2002 to complete. The process culminated in an event to celebrate the launching of the shuttle bus on DME-diesel operation on April 19, 2002. The design of the system on the shuttle bus was patterned after the system developed in the engine laboratory, but also was subjected to a rigorous failure modes effects analysis (FMEA, referred to by Air Products as a ''HAZOP'' analysis) with help from Dr. James Hansel of Air Products. The result of this FMEA was the addition of layers of redundancy and over-pressure protection to the system on the shuttle bus. The system became operational in February 2002. Preliminary emissions tests and basic operation of the shuttle bus took place at the Pennsylvania Transportation Institute's test track facility near the University Park airport. After modification and optimization of the system on the bus, operation on the campus shuttle route began in early June 2002. However, the work and challenges continued as it has been difficult to maintain operability of the shuttle bus due to fuel and component difficulties. In late June 2002, the pump head itself developed operational problems (loss of smooth function) leading to excessive stress on the magnetic coupling and excessive current draw to operate. A new pump head was installed on the system to alleviate this problem and the shuttle bus operated successfully on DME blends from 10-25 vol% on the shuttle bus loop until September 30, 2002. During the period of operation on the campus loop, the bus was pulled from service, operated at the PTI test track and real-time emissions measurements were obtained using an on-board emissions analyzer from Clean Air Technologies International, Inc. Particulate emissions reductions of 60% and 80% were observed at DME blend ratios of 12 vol.% and 25 vol.%, respectively, as the bus was operated over the Orange County driving cycle. Increases in NOx, CO and HC emissions were observed, however. In summary, the conversion of the shuttle bus was successfully accomplished, particulate emissions reductions were observed, but there were operational challenges in the field. Nonetheless, they were able to demonstrate reliable operation of the shuttle bus on DME-diesel blends.

Lubricant return comparison of naphthenic and polyol ester oils in R-134a household refrigeration applications  

SciTech Connect

This paper presents mineral oils and polyol esters as possible lubricant options for domestic refrigeration applications employing R-134a as the heat exchange fluid. A performance comparison, based on data presented, is made between the mineral oils and polyol esters evaluated. To more closely examine lubricant return with N-70 and R-134a and ensure that the oil is not contributing to any deterioration in efficiency due to its accumulation in evaporators, a special test unit was designed with a difficult oil return configuration and its performance carefully monitored. Oil return with a hydrofluorocarbon-miscible polyol ester, R-133-O was also evaluated in this setup and its performance results compared to those obtained with the naphthenic refrigeration oil.

Ab initio calculations of various protonation sites in perfluorodiethyl ether: Models for high temperature lubricant decomposition?  

SciTech Connect

Although perfluoropolyether (PFPE) lubricants have found successful application in spacecraft mechanisms and computer hard drives, there eventual breakdown is irksome, and the mechanism of decomposition is the subject of much scrutiny. However, very little notice is taken of the monomer ethers on which the polymer lubricants are based. Recently, concerted studies of the Lewis base properties of various fluorinated ethers have been performed, both from an experimental and a theoretical viewpoint. As an extension of the theoretical work, this study presents ab initio theoretical consideration of the multiple potential basic sites within perfluorodiethyl ether, (CF{sub 3}CF{sub 2}){sub 2}O, by way of the proton affinity of the molecule at various possible protonation sites (i.e., oxygen and fluorine atoms). The results indicate that although protonation at the oxygen is more energetically favored, protonation at the fluorine is not much higher in energy and provides for formation of an excellent leaving group, HF.

Tribocharging phenomena in hard disk amorphous carbon coatings with and without perfluoropolyether lubricants  

SciTech Connect

Scanning polarization force microscopy was used to study changes in surface potential (tribocharging) caused by the contact between a tungsten carbide tip and the amorphous carbon coating of a hard disk, both when bare and when covered with Zdol-TX lubricant. The surface potential change produced by tip contact decays with time at a rate that is strongly dependent on lubricant coverage and on the presence of oxygen and water vapor in the environment. Two different charging mechanisms are proposed. One involves chemical modification of the surface by removal of oxygen bound to the surface. This gives rise to a potential change that decays with time. Another mechanism involves trapping of charge in states within the energy gap of the insulating carbon film. The potential change due to this trapped charge does not decay over periods much greater than 1 h.

Transverse electrokinetic and microfluidic effects in micro-patterned channels: lubrication analysis for slab geometries  

E-Print Network (OSTI)

Off-diagonal (transverse) effects in micro-patterned geometries are predicted and analyzed within the general frame of linear response theory, relating applied presure gradient and electric field to flow and electric current. These effects could contribute to the design of pumps, mixers or flow detectors. Shape and charge density modulations are proposed as a means to obtain sizeable transverse effects, as demonstrated by focusing on simple geometries and using the lubrication approximation.

New lube oil for stationary heavy fuel engines  

SciTech Connect

An extensively field-tested diesel engine lubricating oil for medium speed, heavy fuel stationary engine applications has been introduced by Caltex Petroleum, in Dallas, Texas. The new oil is similar to a product developed and marketed for marine medium speed heavy fuel propulsion and auxillary engine applications by one of its two parent companies, Chevron. Detailed are results of two field evaluations in Caterpillar 3600 series engines installed at Kimberly Clark (KCPI) and Sime Darby (SDPI), both in the Philippines. Both were one year, 7000-plus hour field evaluations of a new, 40 BN trunk piston engine oil (TPEO), identified as Caltex Delo 3400, SAE 40 engine lube oil. The oil uses the new Phenalate additive technology developed by Chevron Chemical Company`s Oronite Additives Division. This technology is designed to improve engine cleanliness in regard to soft black sludge and piston deposits. The focus of the field evaluations was the performance of the lubricating oil. During controlled tests at Sime Darby, the most noticeable improvement over another technology was in the control of sludge deposits. This improvement was seen in all areas where black sludge forms, such as the rocker cover, crankcase cover and valve assemblies. 4 figs.

Lube oil for medium-speed, heavy-fuel engines  

SciTech Connect

A new generation of trunk-piston engine lube oils has been introduced by Chevron International Marine Lubricants for medium-speed, heavy-fuel, four-stroke engines. The new Chevron Delo 1000, 2000, 3000, and 3400 marine lubricants are specially designed for the demands of medium-speed diesel engines in today`s marine and stationary power markets. The new lube oil has been formulated to provide high levels of engine cleanliness, with low levels of wear. Testing by Chevron engineers shows that the new oils prevent the buildup of black sludge, a sticky, viscous deposit that can accumulate on the surfaces of medium-speed engines that run on heavy residual fuel. The performance of the new lube oils has been thoroughly evaluated by Chevron in a number of ongoing field tests. Results from 5000 hour teardown of a 6600 kW, model 6 MaK 601C engine in the cargo ship MV Germania serve as a good example of the field testing. 3 figs.

DOE Patents (OSTI)

Disclosed is an improved method of reforming a gaseous reformable fuel within a solid oxide fuel cell generator, wherein the solid oxide fuel cell generator has a plurality of individual fuel cells in a refractory container, the fuel cells generating a partially spent fuel stream and a partially spent oxidant stream. The partially spent fuel stream is divided into two streams, spent fuel stream I and spent fuel stream II. Spent fuel stream I is burned with the partially spent oxidant stream inside the refractory container to produce an exhaust stream. The exhaust stream is divided into two streams, exhaust stream I and exhaust stream II, and exhaust stream I is vented. Exhaust stream II is mixed with spent fuel stream II to form a recycle stream. The recycle stream is mixed with the gaseous reformable fuel within the refractory container to form a fuel stream which is supplied to the fuel cells. Also disclosed is an improved apparatus which permits the reforming of a reformable gaseous fuel within such a solid oxide fuel cell generator. The apparatus comprises a mixing chamber within the refractory container, means for diverting a portion of the partially spent fuel stream to the mixing chamber, means for diverting a portion of exhaust gas to the mixing chamber where it is mixed with the portion of the partially spent fuel stream to form a recycle stream, means for injecting the reformable gaseous fuel into the recycle stream, and means for circulating the recycle stream back to the fuel cells.

A NMR-Based Carbon-Type Analysis of Diesel Fuel Blends From Various Sources  

SciTech Connect

In collaboration with participants of the Coordinating Research Council (CRC) Advanced Vehicle/Fuels/Lubricants (AVFL) Committee, and project AVFL-19, the characteristics of fuels from advanced and renewable sources were compared to commercial diesel fuels. The main objective of this study was to highlight similarities and differences among the fuel types, i.e. ULSD, renewables, and alternative fuels, and among fuels within the different fuel types. This report summarizes the carbon-type analysis from 1H and 13C{1H} nuclear magnetic resonance spectroscopy (NMR) of 14 diesel fuel samples. The diesel fuel samples come from diverse sources and include four commercial ultra-low sulfur diesel fuels (ULSD), one gas-to-liquid diesel fuel (GTL), six renewable diesel fuels (RD), two shale oil-derived diesel fuels, and one oil sands-derived diesel fuel. Overall, the fuels examined fall into two groups. The two shale oil-derived samples and the oil-sand-derived sample closely resemble the four commercial ultra-low sulfur diesels, with SO1 and SO2 most closely matched with ULSD1, ULSD2, and ULSD4, and OS1 most closely matched with ULSD3. As might be expected, the renewable diesel fuels, with the exception of RD3, do not resemble the ULSD fuels because of their very low aromatic content, but more closely resemble the gas-to-liquid sample (GTL) in this respect. RD3 is significantly different from the other renewable diesel fuels in that the aromatic content more closely resembles the ULSD fuels. Fused-ring aromatics are readily observable in the ULSD, SO, and OS samples, as well as RD3, and are noticeably absent in the remaining RD and GTL fuels. Finally, ULSD3 differs from the other ULSD fuels by having a significantly lower aromatic carbon content and higher cycloparaffinic carbon content. In addition to providing important comparative compositional information regarding the various diesel fuels, this report also provides important information about the capabilities of NMR spectroscopy for the detailed characterization and comparison of fuels and fuel blends.

Effects of potential additives to promote seal swelling on the thermal stability of synthetic jet fuels  

SciTech Connect

Synthetic fuels derived from the Fischer-Tropsch (F-T) process using natural gas or coal-derived synthesis gas as feedstocks can be used for powering of ground vehicles, aircraft and ships. Because of their chemical and physical properties, F-T fuels will probably require additives in order to meet specifications with respect to lubricity and seal swell capability for use in ground and air vehicles. These additives can include oxygenates and compounds containing other heteroatoms that may adversely affect thermal stability. In order to understand what additives will be the most beneficial, a comprehensive experimental and computational study of conventional and additized fuels has been undertaken. The experimental approach includes analysis of the trace oxygenate and nitrogen-containing compounds present in conventional petroleum-derived fuels and trying to relate their presence (or absence) to changes in the desired properties of the fuels. This paper describes the results of efforts to test the thermal stability of synthetic fuels and surrogate fuels containing single-component additives that have been identified in earlier research as the best potential additives for promoting seal swelling in synthetic fuels, as well as mixtures of synthetic and petroleum-derived fuels.

Near-frictionless carbon coatings for spark-ignited direct-injected fuel systems. Final report, January 2002.  

SciTech Connect

This report describes an investigation by the Tribology Section of Argonne National Laboratory (ANL) into the use of near-frictionless carbon (NFC) coatings for spark-ignited, direct-injected (SIDI) engine fuel systems. Direct injection is being pursued in order to improve fuel efficiency and enhance control over, and flexibility of, spark-ignited engines. SIDI technology is being investigated by the Partnership for a New Generation of Vehicles (PNGV) as one route towards meeting both efficiency goals and more stringent emissions standards. Friction and wear of fuel injector and pump parts were identified as issues impeding adoption of SIDI by the OTT workshop on ''Research Needs Related to CIDI and SIDI Fuel Systems'' and the resulting report, Research Needs Related to Fuel Injection Systems in CIDI and SIDI Engines. The following conclusions were reached: (1) Argonne's NFC coatings consistently reduced friction and wear in existing and reformulated gasolines. (2) Compared to three commercial DLC coatings, NFC provided the best friction reduction and protection from wear in gasoline and alternative fuels. (3) NFC was successfully deposited on production fuel injectors. (4) Customized wear tests were performed to simulate the operating environment of fuel injectors. (5) Industry standard lubricity test results were consistent with customized wear tests in showing the friction and wear reduction of NFC and the lubricity of fuels. (6) Failure of NFC coatings by tensile crack opening or spallation did not occur, and issues with adhesion to steel substrates were eliminated. (7) This work addressed several of the current research needs of the OAAT SIDI program, as defined by the OTT report Research Needs Related to Fuel Injection Systems in CIDI and SIDI Engines.

Novel injector techniques for coal-fueled diesel engines  

SciTech Connect

This report, entitled Novel Injector Techniques for Coal-Fueled Diesel Engines,'' describes the progress and findings of a research program aimed at development of a dry coal powder fuel injector in conjunction with the Thermal Ignition Combustion System (TICS) concept to achieve autoignition of dry powdered coal in a single-cylinder high speed diesel engine. The basic program consisted of concept selection, analysis and design, bench testing and single cylinder engine testing. The coal injector concept which was selected was a one moving part dry-coal-powder injector utilizing air blast injection. Adiabatics has had previous experience running high speed diesel engines on both direct injected directed coal-water-slurry (CWS) fuel and also with dry coal powder aspirated into the intake air. The Thermal Ignition Combustion System successfully ignited these fuels at all speeds and loads without requiring auxiliary ignition energy such as pilot diesel fuel, heated intake air or glow or spark plugs. Based upon this prior experience, it was shown that the highest efficiency and fastest combustion was with the dry coal, but that the use of aspiration of coal resulted in excessive coal migration into the engine lubrication system. Based upon a desire of DOE to utilize a more modern test engine, the previous naturally-aspirated Caterpillar model 1Y73 single cylinder engine was replaced with a turbocharged (by use of shop air compressor and back pressure control valve) single cylinder version of the Cummins model 855 engine.

Miscibility, solubility, viscosity, and density measurements for R-236fa with potential lubricants. Final report  

SciTech Connect

The report gives results of miscibility, solubility, viscosity, and density measurements for refrigerant R-236fa and two potential lubricants. (The data are needed to determine the suitability of refrigerant/lubricant combinations for use in refrigeration systems.) The tested oils were pentaerythritol ester mixed-acid (ISO68), hereafter SW-68 manufactured by Castrol, and polyol ester mixed-acid (ISO46), hereafter Arctic-46 manufactured by Mobil. Miscibility was measured in a series of miniature test cells submerged in a constant temperature bath, precisely controlled over a temperature range of -50 to 90 C. Solubility, viscosity, and density data were also obtained for R-236fa mixed with the two oils for a refrigerant concentration of 0 to 40 wt % refrigerant over a temperature range of 30 to 100 C. This research shows that: (1) solubility, viscosity, and density are functions of temperature and concentration, (2) solubility increases with increasing temperature and refrigerant concentration (i.e., mass fraction of refrigerant). (3) viscosity decreases with increasing temperature and refrigerant concentration, and (4) density decreases with increasing temperature but increases with increasing refrigerant concentration. R-114 and naphthenic mineral oil were also tested.

Thin film hydrodynamic lubrication of flying heads in magnetic disk storages  

Science Journals Connector (OSTI)

Typical hydrodynamic lubrication problems commonly encountered in the ultrathin spacing between a computer flying head and a magnetic disk are reviewed. In magnetic disk storages, minimizing the spacing between the head and disk is essential to promote the largest possible increase in magnetic bit density. In the small (nearly 1.0 ?m) spacing that has recently been attained, the rarefaction effects owing to the molecular mean free path become dominant. Specifically, in this paper the three governing equations resulting from the first- and second-order slip-flow models and from the linearized Boltzmann equation are compared. Next, some numerical approaches to eliminating the instability in pressure distribution in the high bearing number region are described. Surface roughness effects are also a principal concern in thin spacing. A mixed lubrication model which enables the analysis of the start/stop operation and the average film thickness theory for one- and two-dimensional roughnesses is summarized. Finally, from the viewpoint of practical head design, the slider dynamic characteristics and related slider design factors are discussed.

Prediction of refrigerant-lubricant viscosity using the general PC-SAFT friction theory  

Science Journals Connector (OSTI)

Abstract In this work, a friction theory (f-theory) viscosity model founded on the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state (EoS) was used to calculate the viscosity of refrigerant-oil mixtures. The model, which links viscosity to the repulsive and attractive pressure terms of the PC-SAFT EoS, can provide satisfactory viscosity predictions of mixtures of carbon dioxide (R-744) and two synthetic lubricants, namely, a polyolester (POE) ISO VG 68 and an alkylbenzene (AB) ISO VG 32, as well as mixtures of isobutane (R-600a) and two other synthetic lubricants, a POE ISO VG 7 and an AB ISO VG 5. The root-mean square (RMS) deviations related to the viscosity prediction were 0.69% (R-600a/POE ISO 7), 0.99% (R-600a/AB ISO VG 5), 3.16% (R-744/POE ISO VG 68) and 3.18% (R-744/AB ISO VG 32).

Coal based fuels, fuel systems and alternative fuels  

SciTech Connect

The introduction of coal based fuel systems such as coal/air and coal water mixtures was an attempt to minimize the use of heavy fuel oils in large scale power generation processes. This need was based on forecasts of fuel reserves and future pricing of fuel oils, therefore economic considerations predominated over environmental benefits, if any, which could result from widespread use of these fuels. Coal continued as the major fuel used in the power generation industry and combustion systems were developed to minimize gaseous emissions, such as NOx. Increasing availability of natural gas led to consideration of its use in combination with coal in fuel systems involving combined cycle or topping cycle operations. Dual fuel coal natural gas operations also offered the possibility of improved performance in comparison to 100% coal based fuel systems. Economic considerations have more recently looked at emulsification of heavy residual liquid fuels for consumption in power generation boiler and Orimulsion has emerged as a prime example of this alternative fuel technology. The paper will discuss some aspects of the burner technology related to the application of these various coal based fuels, fuel systems and alternative fuels in the power generation industry.

LMFBR fuel component costs  

SciTech Connect

A significant portion of the cost of fabricating LMFBR fuels is in the non-fuel components such as fuel pin cladding, fuel assembly ducts and end fittings. The contribution of these to fuel fabrication costs, based on FFTF experience and extrapolated to large LMFBR fuel loadings, is discussed. The extrapolation considers the expected effects of LMFBR development programs in progress on non-fuel component costs.

Naphthenic acids as antiwear additives for jet fuels  

SciTech Connect

One of the ways in which the antiwear properties of jet fuels can be improved is the use of lubricity agents, otherwise known as antiwear additives. Among the various compounds that have antiwear properties in these fuels, naphthenic, acids merit special attention. These are alicyclic carboxylic acids, in most cases monobasic, with five- and six-membered carbon rings; they have the general formula R(CH{sub 2}){sub n}COOH, where R is a naphthene radical. Natural naphthenic acids consist mainly of acids of the cyclopentane series, beginning with the simplest, in particular cyclopentylacetic acid. The lower naphthenic acids are monocyclic; the higher acids, beginning with C{sub 13}, are bicyclic and polycyclic. Naphthenic acids of the cyclohexane series are encountered less frequently; they may be found, for example, in Baku, California, and Sakhalin crudes. The most widely used method for obtaining naphthenic acids is the treatment of light distillates, lube distillates, and diesel fuels. The standard GOST 13302-77 establishes several grades of naphthenic acids, depending on the raw material and the production technology. This work was aimed at the utilization of wastes containing naphthenic acids, with subsequent use as jet fuel additives.

A new emergency lubricating-oil system for steam turbine generators: Final report  

SciTech Connect

A positive-displacement pump, powered by a turbine-shaft driven permanent magnet generator (PMG) can be used to provide lubricating oil over nearly the entire turbine generator speed range. The concept offers high reliability through its simplicity; switchgear, batteries and other auxiliaries are eliminated by hard-wiring the PMG to the pump induction drive motor. In this study, an existing PMG supplying power to the electrohydraulic control (EHC) system was evaluated as the power supply for an induction motor-driven screw pump running in a ''wafting'' mode as a backup to a conventional dc emergency oil system. The screw pump rotates all the time that the turbine shaft turns; check valves allow it to deliver oil instantly if the system pressure falls. It was found that the pump drive motor would start and run reliably with no adverse effects on the PMG or the electrohydraulic control (EHC) system. 6 refs., 23 figs., 11 tabs.

Effects of self-assembled monolayer and PFPE lubricant on wear characteristics of flat silicon tips.  

SciTech Connect

The effects of self-assembled monolayer (SAM) and perfluoropolyether (PFPE) lubricant on the wear characteristics of flat silicon tips were investigated. The wear test consisted of sliding the silicon tips fabricated on a flat silicon specimen against SAM and PFPE (Z-tetraol) coated silicon (100) wafer. The tips were slid at a low speed for about 15 km under an applied load of 39.2 {micro}N. The wear volume of the tip was obtained by measuring the tip profile using an Atomic Force Microscope (AFM). It was found that the coatings were effective in reducing the wear of the tips by an order of magnitude from 10{sup -6} to 10{sup -7}.

Closed-loop study of the effects of multicycle re-refining of automotive lubricating oil  

SciTech Connect

Twenty-five gallons of a hydrofinished virgin lubricating oil basestock was blended with additives into a 10W30 crankcase oil. After the engines had been pruged with a flush oil, 11 vehicles were charged with the blended virgin oil. Mileages ranging from 2000 to over 3000 miles of use were accumulated before the oil was drained, re-refined and recharged to the vehicles. This cycle was repeated until the oil had been re-refined three times. At each stage, detailed analyses and compound characterizations were performed on both the oil being recycled and on the same oil which was re-refined but never charged to vehicles. The data showed no significant change in the composition of the base oil, except for a minor buildup of additive base oil, which was expected.

Theory of a Possible Mechanism for Lubrication and Surface Protection by an Electrically Neutral Hydrogels  

E-Print Network (OSTI)

It is demonstrated that polymers sticking out of the surface of a neutral hydrogel are capable of preventing adhesive forces from pulling a hydrogel into close contact with a surface against which it is pressed. The proposed mechanism for lubrication or surface protection suggests a possible mechanism for protecting the cornea from a contact lens, which is held against the eye by Laplace pressure. This mechanism, however, is only able to keep a gel coated surface from sticking to a surface against which it is pressed, if the gel and surface are bathed in fluid. Expected optical properties of the gel-surface interface are discussed, in order to suggest possible ways to study the gel-solid interface experimentally.

Thickness and density of adsorbed additive layer on metal surface in lubricant by neutron reflectometry  

Science Journals Connector (OSTI)

The thickness and density of the adsorbed additive layer on a metal surface in lubricant were directly measured by neutron reflectometry. First, two kinds of metal surfaces, iron and copper, on ultra-flat silicon blocks were prepared by physical vapor deposition. After that, each target surface was analyzed by neutron reflectometry in air, in base oil and in base oil with an additive. Poly-alpha-olefin was used as the base oil, while deuterated acetic acid was used as an additive. Fitting operation based on Parratt's theory showed that the thicknesses of the adsorbed layers on the iron and copper surfaces were quite thin, only 2.0 nm. The friction coefficients of the metal surfaces measured by a ball-on-disk tribometer decreased considerably when the acetic acid was added to the base oil. It was concluded that the additive adsorbed layers on the metal surfaces considerably affected friction properties despite being only several nanometers thick.

Chapter 3 - Fuels for Fuel Cells  

Science Journals Connector (OSTI)

Publisher Summary This chapter deals with various types of liquid fuels and the relevant chemical and physical properties of these fuels as a means of comparison to the fuels of the future. It gives an overview of the manufacture and properties of the common fuels as well as a description of various biofuels. A fuel mixture usually contains a wide range of organic compounds (usually hydrocarbons). The specific mixture of hydrocarbons gives a fuel its characteristic properties, such as boiling point, melting point, density, viscosity, and a host of other properties. Depending on the application (stationary, central power, remote, auxiliary, transportation, military, etc.), there are a wide range of conventional fuels, such as natural gas, liquefied petroleum gas, light distillates, methanol, ethanol, dimethyl ether, naphtha, gasoline, kerosene, jet fuels, diesel, and biodiesel, that could be used in reforming processes to produce hydrogen (or hydrogen-rich synthesis gas) to power fuel cells. Fossils fuels include gaseous fuels, gasoline, kerosene, diesel fuel, and jet fuels. Gaseous fuels include natural gas and liquefied petroleum gas. Types of gasoline include automotive gasoline, aviation gasoline, and gasohol. Some additives added into gasoline are antioxidants, corrosion inhibitors, demulsifiers, anti-icing, dyes and markers, drag reducers, and oxygenates.
