Update on Transition to Ultra-Low-Sulfur Diesel Fuel (released in AEO2006)  

Reports and Publications (EIA)

On November 8, 2005, the Environmental Protection Agency (EPA) Administrator signed a direct final rule that will shift the retail compliance date for offering ultra-low sulfur diesel (ULSD) for highway use from September 1, 2006, to October 15, 2006. The change will allow more time for retail outlets and terminals to comply with the new 15 parts per million (ppm) sulfur standard, providing time for entities in the diesel fuel distribution system to flush higher sulfur fuel out of the system during the transition. Terminals will have until September 1, 2006, to complete their transitions to ULSD. The previous deadline was July 15, 2006.

The effects of gas-to-oil rate in ultra low sulfur diesel hydrotreating  

Science Journals Connector (OSTI)

Hydrotreating has become a critical refining process as fuel sulfur specifications are tightened around the world. Recently, refiners in the United States have been learning how to optimize the performance of ultra low sulfur diesel (ulsd) hydrotreaters. The gas-to-oil feed rate ratio is known to be an important variable in this respect. It is well known that the gas-to-oil rate must be kept high enough to maintain the desired hydrogen partial pressure through the hydrotreating reactor, and to minimize the inhibiting effect of hydrogen sulfide. A lesser-known effect is the effect of gas-to-oil rate on the vapor–liquid equilibrium in the reactor. Changing the gas-to-oil rate alters the distribution of reactants between vapor and liquid in a way that changes the relative reaction rates of different sulfur compounds. This paper presents some pilot plant data and analysis showing this effect of phase equilibrium in deep diesel desulfurization. The effect can be modeled using the Frye–Mosby equation, which accounts for the effects of feed vaporization and phase equilibrium on the reaction rates of individual sulfur compounds in a trickle bed hydrotreater.

Particle size distributions from heavy-duty diesel engine operated on low-sulfur marine fuel  

Science Journals Connector (OSTI)

Particulate matter (PM) emission characteristics of a four-stroke diesel engine were investigated while operating on low-sulfur marine gas oil. PM size distributions appeared to be unimodal (accumulation mode) with fairly constant count median diameter (CMD) of 55–65 nm for all test modes at maximum engine speed. The slightly bigger CMD of around 76 nm for unimodal particle size distributions at 1080 rpm at medium- and high-load conditions was observed. The bimodal size distribution was registered only at very low load with nuclei CMD being below 15 nm, accumulation CMD of around 82 nm and percentage of nanoparticles of around 65%. The study of primary dilution air temperature (PDT) effect revealed a significant reduction in total particle number for all operating conditions when PDT was increased from 30 °C to 400 °C. This also had an effect on particle CMD values and is believed to be due to evaporation of sulfuric acid with bound water and certain organic fractions that were formed during dilution process (at PDT = 30 °C). At very low load intermediate speed conditions, the heating of dilution air had a very little effect on the nucleation mode, which could suggest that it primarily consists of heavy hydrocarbons associated with lubrication oil.

Demand, Supply, and Price Outlook for Low-Sulfur Diesel Fuel  

Gasoline and Diesel Fuel Update (EIA)

To help ensure that sulfates in engine exhaust do not To help ensure that sulfates in engine exhaust do not prevent manufacturers of heavy-duty diesel engines from meeting new particulate emissions standards for 1994 and later model years, 1 the Clean Air Act Amend- ments of 1990 (CAAA90) require refiners to reduce the sulfur content of on-highway diesel fuel from current average levels of 0.30 percent by weight to no more than 0.05 percent by weight. The new standard, which goes into effect October 1, 1993, also requires that on-highway diesel fuel have a minimum cetane index of 40 or a maximum aromatic content of 35 percent by volume. 2 (See list of terms and definitions on the fol- lowing page.) This provision is designed to prevent any future rises in aromatics levels. 3 Since the direct mea- surement of aromatics is complex, a minimum cetane

Adequacy of low-sulfur coal supplies for meeting acid rain requirements  

SciTech Connect

As we have shown, acid rain legislation would create a large demand for low-sulfur bituminous coals. These coals are primarily found in Central Appalachia and in parts of the West, and would displace much of the highersulfur coal production now coming from the Midwest and Northern Appalachia. The magnitude of the related shifts in coal production are potentially huge. Previously, it has been assumed that these shifts in demands could be met by the industry. This paper has tried to highlight possible difficulties in actually meeting such demands. In the near-term, these difficulties concern the ability of the industry to develop mines and of the transportation industry to ship the coal. In the longer-term, questions can be raised regarding the amount, the quality, and the mineability of low-sulfur bituminous coal reserves. These potential difficulties in coal supply could affect attainment of the legislative goals. If not addressed and resolved in a timely fashion, the results could be a higher cost to meeting legislative goals and/or a longer time required to meet them.

Adsorptive desulfurization of low sulfur diesel fuel using palladium containing mesoporous silica synthesized via a novel in-situ approach  

Science Journals Connector (OSTI)

Abstract In this work, a novel in-situ synthesis route was applied for preparation of an adsorbent, i.e. palladium containing MCM-41. At first, a hydrophobic palladium precursor was added to the ethanolic micellar solution followed by vacuum distillation of ethanol which decreases the hydrophobic characteristic of the solution. Distillation caused diffusion of hydrophobic palladium precursor into the hydrophobic core of the micelles. Then, tetraethyl orthosilicate was added to the above solution and the silicate spices arranged around the palladium containing micelles. The XRD, N2 physisorption and TEM studies revealed that 4 wt.% palladium loading was achieved without considerable loss of pore ordering. H2-TPR showed that the palladium nanoparticles were accessible for hydrogen molecules. Adsorptive desulfurization of low sulfur diesel fuel was then investigated using synthesized samples. The effect of three valuable parameters, i.e., temperature (25, 75, 150 and 200 °C), concentration of palladium (2, 4 and 5 wt.%) and feed flow rate (0.3 and 1 mL/min) were tested using a fixed-bed flowing device. The highest sulfur break through adsorption capacity and total sulfur adsorption capacity obtained at 200 °C, 0.3 mL/min of feed flow rate and 4 wt.% of palladium concentration were 1.67 and 2.35 mg sulfur/g adsorbent, respectively.

MHUG process for production of low sulfur and low aromatic diesel fuel. [Medium-pressure Hydro UpGrading  

SciTech Connect

A new hydro-upgrading process operated under medium pressure has been developed to reduce the sulfur and the aromatics content in light cycle oil (LCO). Two catalysts were used in series in this technology. The commercial RN-1 catalyst, which is known as having high activity in hydrodenitrogenation, desulfurization and aromatic saturation, was chosen as the first catalyst. The second one was a nickel-tungsten zeolite catalyst, named RT-5, which was developed by RIPP specially for hydrogenolysis of naphthenic and aromatic hydrocarbons. The pilot plant tests showed that high quality diesel oil with aromatics content less than 20 v% and sulfur content less than 0.05 wt% could be produced from various LCO/straight-run-gas-oil (SRGO) blended feedstocks under hydrogen partial pressure of 6.4 MPa. The reaction temperature and overall space velocity (S.V.) varied in the range of 350--380 C and 0.6--1.2 h[sup [minus]1], respectively, depending on the properties of the feedstocks to be processed and the upgrading depth required. Several examples presented also illustrated that this technology could be used to prepare catalytic reforming feedstock as well, which is in urgent need in China. A life test operated in relatively high severity for 3,000 hr. indicated that the catalysts possessed excellent stability. A commercial demonstration unit has been running well since the last Oct 1.

Warm Winters Held Heating Oil Demand Down While Diesel Grew  

Gasoline and Diesel Fuel Update (EIA)

Most of the remaining charts deal with total distillate demand. Total distillate demand includes both diesel and heating oil. These are similar products physically, and prior to the low sulfur requirements for on-road diesel fuel, were used interchangeably. But even today, low sulfur diesel can be used in the heating oil market, but low sulfur requirements keep heating oil from being used in the on-road transportation sector. The seasonal increases and decreases in stocks stem from the seasonal demand in heating oil shown as the bottom red line. Heating oil demand increases by more than 50 percent from its low point to its high

Reserves and potential supply of low-sulfur Appalachian coal. Final report  

SciTech Connect

This project has two objectives. The first is to develop and test a methodology for determining economically mineable reserves of low-sulfur Appalachian coal. The second is to appraise the potential supply response to a very large increase in demand for low-sulfur Appalachian coal. The reserve determination procedure developed in the project applies criteria similar to those employed by mining engineers in assessing the commercial feasibility of mining properties. The procedure is relatively easy to apply, could be used to develop reserve estimates for a large sample of mining blocks for under $500,000, and produces reserve estimates very different from those produced from the criteria that have been used by the United States Bureau of Mines: with the more rigorous method developed in this project surface mineable reserves are much larger and deep mineable reserves are less than with the Bureau of Mines method. The appraisal of potential low-sulfur coal supply response assessed excess capacity, coal mining company outlook on reserves, and coal quality requirements. The appraisal concluded that ample coal meeting most buyers' requirements will probably be available in the near or long term at a price under $45 in 1984 dollars. However, coal quality requirements may prove a constraint for some buyers, and an upward surge in prices would probably occur in the event of legislation imposing requirements leading to greatly increased low-sulfur coal demand. 14 refs., 24 figs., 15 tabs.

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.

ULTRA-LOW SULFUR REDUCTION EMISSION CONTROL DEVICE/DEVELOPMENT OF AN ON-BOARD FUEL SULFUR TRAP  

SciTech Connect

Honeywell is actively working on a 3-year program to develop and demonstrate proof-of-concept for an ''on-vehicle'' desulfurization fuel filter for heavy-duty diesel engines. Integration of the filter into the vehicle fuel system will reduce the adverse effects sulfur has on post combustion emission control devices such as NO{sub x} adsorbers. The NO{sub x} adsorber may be required to meet the proposed new EPA Tier II and ''2007-Rule'' emission standards. The proposed filter concept is based on Honeywell's reactive filtration technology and experience in liquids handling and conditioning. A regeneration and recycling plan for the spent filters will also be examined. We have chosen to develop and demonstrate this technology based on criteria set forth for a heavy duty CIDI engine system because it represents a more challenging set of conditions of service intervals and overall fuel usage over light duty systems. It is anticipated that the technology developed for heavy-duty applications will be applicable to light-duty as well. Further, technology developed under this proposal would also have application for the use of liquid based fuels for fuel cell power generation. The program consists of four phases. Phase I will focus on developing a concept design and analysis and resolution of technical barriers concerning removal of sulfur-containing species in low sulfur fuels. In Phase II we will concentrate on prototype filter design and preparation followed by qualification testing of this component in a fuel line application. Phase III will study life cycle and regeneration options for the spent filter. Phase IV will focus on efficacy and life testing and component integration. The project team will include a number of partners, with Honeywell International as the prime contractor. The partners include an emission control technology developer (Honeywell International), a fuel technology developer (Marathon Ashland Petroleum), a catalyst technology developer (Johnson Matthey), a CIDI engine manufacturer (Mack Trucks Inc.), a filter recycler (American Wastes Industries), and a low-sulfur fuel supplier (Equilon, a joint venture between Shell and Texaco).

Retail Diesel Fuel Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

Along with heating oil prices, the distillate supply squeeze has Along with heating oil prices, the distillate supply squeeze has severely impacted diesel fuel prices, especially in the Northeast. Diesel fuel is bascially the same product as home heating oil. The primary difference is that diesel has a lower sulfur content. When heating oil is in short supply, low sulfur diesel fuel can be diverted to heating oil supply. Thus, diesel fuel prices rise with heating heating oil prices. Retail diesel fuel prices nationally, along with those of most other petroleum prices, increased steadily through most of 1999. But prices in the Northeast jumped dramatically in the third week of January. Diesel fuel prices in New England rose nearly 68 cents per gallon, or 47 percent, between January 17 and February 7.

The John Deere E diesel Test & Research Project  

SciTech Connect

Three non-road Tier II emissions compliant diesel engines manufactured by John Deere were placed on a durability test plan of 2000 hours each at full load, rated speed (FLRS). The fuel was a blend of 10% fuel ethanol and 90% low sulfur #2 diesel fuel. Seven operational failures involving twenty seven fuel system components occurred prior to completion of the intended test plan. Regulated emissions measured prior to component failure indicated compliance to Tier II certification goals for the observed test experience. The program plan included operating three non-road Tier II diesel engines for 2000 hours each monitoring the regulated emissions at 500 hour intervals for changes/deterioration. The program was stopped prematurely due to number and frequency of injection system failures. The failures and weaknesses observed involved injector seat and valve wear, control solenoid material incompatibility, injector valve deposits and injector high pressure seal cavitation erosion. Future work should target an E diesel fuel standard that emphasizes minimum water content, stability, lubricity, cetane neutrality and oxidation resistance. Standards for fuel ethanol need to require water content no greater than the base diesel fuel standard. Lubricity bench test standards may need new development for E diesel.

Central Appalachia: Production potential of low-sulfur coal  

SciTech Connect

The vast preponderance of eastern US low sulfur and 1.2-lbs SO{sub 2}/MMBtu compliance coal comes from a relatively small area composed of 14 counties located in eastern Kentucky, southern West Virginia and western Virginia. These 14 counties accounted for 68% of all Central Appalachian coal production in 1989 as well as 85% of all compliance coal shipped to electric utilities from this region. A property-by-property analysis of total production potential in 10 of the 14 counties (Floyd, Knott, Letcher, Harlan, Martin and Pike in Kentucky and Boone, Kanawha, Logan and Mingo in West Virginia) resulted in the following estimates of active and yet to be developed properties: (1) total salable reserves for all sulfur levels were 5.9 billion tons and (2) 1.2-lbs. SO{sub 2}/MMBtu compliance'' reserves totaled 2.38 billion tons. This potential supply of compliance coal is adequate to meet the expanded utility demand expected under acid rain for the next 20 years. Beyond 2010, compliance supplies will begin to reach depletion levels in some areas of the study region. A review of the cost structure for all active mines was used to categorize the cost structure for developing potential supplies. FOB cash costs for all active mines in the ten counties ranged from $15 per ton to $35 per ton and the median mine cost was about $22 per ton. A total of 47 companies with the ability to produce and ship coal from owned or leased reserves are active in the ten-county region. Identified development and expansion projects controlled by active companies are capable of expanding the region's current production level by over 30 million tons per year over the next twenty years. Beyond this period the issue of reserve depletion for coal of all sulfur levels in the ten county region will become a pressing issue. 11 figs., 12 tabs.

This article presents nondestructive neutron computed tomography (nCT) measurements of Diesel Particulate Filters (DPFs) as a method to measure ash and soot loading in the filters. Uncatalyzed and unwashcoated 200cpsi cordierite DPFs exposed to 100% biodiesel (B100) exhaust and conventional ultra low sulfur 2007 certification diesel (ULSD) exhaust at one speed-load point (1500rpm, 2.6bar BMEP) are compared to a brand new (never exposed) filter. Precise structural information about the substrate as well as an attempt to quantify soot and ash loading in the channel of the DPF illustrates the potential strength of the neutron imaging technique.

Process for producing low-sulfur boiler fuel by hydrotreatment of solvent deashed SRC  

DOE Patents (OSTI)

In this invention, a process is disclosed characterized by heating a slurry of coal in the presence of a process-derived recycle solvent and passing same to a dissolver zone, separating the resultant gases and liquid/solid products therefrom, vacuum distilling the liquid/solids products, separating the portions of the liquid/solids vacuum distillation effluent into a solid ash, unconverted coal particles and SRC material having a boiling point above 850.degree. F. and subjecting same to a critical solvent deashing step to provide an ash-free SRC product. The lighter liquid products from the vacuum distillation possess a boiling point below 850.degree. F. and are passed through a distillation tower, from which recycled solvent is recovered in addition to light distillate boiling below 400.degree. F. (overhead). The ash-free SRC product in accompanyment with at least a portion of the process derived solvent is passed in combination to a hydrotreating zone containing a hydrogenation catalyst and in the presence of hydrogen is hydroprocessed to produce a desulfurized and denitrogenized low-sulfur, low-ash boiler fuel and a process derived recycle solvent which is recycled to slurry the coal in the beginning of the process before heating.

Relevance of valve overlap for meeting Euro 5 soot emissions requirements during load transient process in heavy duty diesel engines  

Science Journals Connector (OSTI)

This work describes the influence on performance and soot emissions of using different valve overlap camshafts during load transient processes in a heavy duty (HD) diesel engine equipped with a variable geometry turbine (VGT) in its turbocharger and a selective catalyst reactor (SCR) in the exhaust line. Based on the results of experiments and calculations, in this paper a description is given of how the valve timing affects the instantaneous exhaust and intake pressure, the short-circuit of the air mass flow, the prejudicial backflows, the performance of the turbine and hence the general performance and pollutant emissions of a VGT equipped HD diesel engine during a transient process. The paper concludes that very low or no overlap is imperative if a VGT is used to meet forthcoming pollutant emissions restrictions and to improve the transient response of HD turbocharged diesel engines.

A Fundamental Consideration on NOx Adsorber Technology for DI Diesel Application  

SciTech Connect

Diesel engines are far more efficient than gasoline engines of comparable size, and emit less greenhouse gases that have been implicated in global warming. In 2000, the US EPA proposed very stringent emissions standards to be introduced in 2007 along with low sulfur (< 15 ppm) diesel fuel. The California Air Resource Board (CARB) has also established the principle that future diesel fueled vehicles should meet the same low emissions standards as gasoline fueled vehicles and the EPA followed suit with its Tier II emissions regulation. Achieving such low emissions cannot be done through engine development and fuel reformulation alone, and requires application of NOx and particulate matter (PM) aftertreatment control devices. There is a widespread consensus that NOx adsorbers and particulate filter are required in order for diesel engines to meet the 2007 emissions regulations for NOx and PM. In this paper, the key exhaust characteristics from an advanced diesel engine are reviewed. Development of the NOx adsorber technology is discussed. Spectroscopic techniques are applied to understand the underlying chemical reactions over the catalyst surface during NOx trapping and regeneration periods. In-situ surface probes are useful in providing not only thermodynamic and kinetics information required for model development but also a fundamental understanding of storage capacity and degradation mechanisms. The distribution of various nitration/sulfation species is related to surface basicity. Surface displacement reactions of carbonates also play roles in affecting the trapping capability of NOx adsorbers. When ultralow-S fuel is used as a reductant during the regeneration, sulfur induced performance degradation is still observed in an aged catalyst. Other possible sources related to catalyst deactivation include incomplete reduction of surface nitration, coke formation derived from incomplete hydrocarbon burning, and lubricant formulations. Sulfur management and the direction of future work for the successful implementation of such integrated engine and aftertreatment technology are discussed.

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.

Alaska has 4. 0 trillion tons of low-sulfur coal: Is there a future for this resource  

SciTech Connect

The demand for and use of low-sulfur coal may increase because of concern with acid rain. Alaska's low-sulfur coal resources can only be described as enormous: 4.0 trillion tons of hypothetical onshore coal. Mean total sulfur content is 0.34% (range 0.06-6.6%, n = 262) with a mean apparent rank of subbituminous B. There are 50 coal fields in Alaska; the bulk of the resources are in six major fields or regions: Nenana, Cook Inlet, Matanuska, Chignik-Herendeen Bay, North Slope, and Bering River. For comparison, Carboniferous coals in the Appalachian region and Interior Province have a mean total sulfur content of 2.3% (range 0.1-19.0%, n = 5,497) with a mean apparent rank of high-volatile A bituminous coal, and Rocky Mountain and northern Great Plains Cretaceous and Tertiary coals have a mean total sulfur content of 0.86% (range 0.02-19.0%, n = 2,754) with a mean apparent rank of subbituminous B. Alaskan coal has two-fifths the total sulfur of western US coals and one-sixth that of Carboniferous US coals. Even though Alaska has large resources of low-sulfur coal, these resources have not been developed because of (1) remote locations and little infrastructure, (2) inhospitable climate, and (3) long distances to potential markets. These resources will not be used in the near future unless there are some major, and probably violent, changes in the world energy picture.

Drive cycle analysis of butanol/diesel blends in a light-duty vehicle.  

SciTech Connect

The potential exists to displace a portion of the petroleum diesel demand with butanol and positively impact engine-out particulate matter. As a preliminary investigation, 20% and 40% by volume blends of butanol with ultra low sulfur diesel fuel were operated in a 1999 Mercedes Benz C220 turbo diesel vehicle (Euro III compliant). Cold and hot start urban as well as highway drive cycle tests were performed for the two blends of butanol and compared to diesel fuel. In addition, 35 MPH and 55 MPH steady-state tests were conducted under varying road loads for the two fuel blends. Exhaust gas emissions, fuel consumption, and intake and exhaust temperatures were acquired for each test condition. Filter smoke numbers were also acquired during the steady-state tests.

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.

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.

FUEL FORMULATION EFFECTS ON DIESEL FUEL INJECTION, COMBUSTION, EMISSIONS AND EMISSION CONTROL  

SciTech Connect

This paper describes work under a U.S. DOE sponsored Ultra Clean Fuels project entitled ''Ultra Clean Fuels from Natural Gas,'' Cooperative Agreement No. DE-FC26-01NT41098. In this study we have examined the incremental benefits of moving from low sulfur diesel fuel and ultra low sulfur diesel fuel to an ultra clean fuel, Fischer-Tropsch diesel fuel produced from natural gas. Blending with biodiesel, B100, was also considered. The impact of fuel formulation on fuel injection timing, bulk modulus of compressibility, in-cylinder combustion processes, gaseous and particulate emissions, DPF regeneration temperature and urea-SCR NOx control has been examined. The primary test engine is a 5.9L Cummins ISB, which has been instrumented for in-cylinder combustion analysis and in-cylinder visualization with an engine videoscope. A single-cylinder engine has also been used to examine in detail the impacts of fuel formulation on injection timing in a pump-line-nozzle fueling system, to assist in the interpretation of results from the ISB engine.

Effect of Biodiesel Blending on the Speciation of Soluble Organic Fraction from a Light Duty Diesel Engine  

SciTech Connect

Soy methyl ester (SME) biodiesel was volumetrically blended with 2007 certification ultra low sulfur diesel (ULSD) fuel and run in a 1.7L direct-injection common rail diesel engine at one speed-load point (1500rpm, 2.6bar BMEP). Engine fueling rate and injection timing were adjusted to maintain a constant load, while particulate samples were collected in a diesel particulate filter (DPF) and with a dilution tunnel sampling train. The samples collected at these two locations were found to contain different levels of soluble organic fraction (SOF) and the different hydrocarbon species in the SOF. This observation indicates that traditional SOF measurements, in light of the specific sampling procedure used, may not be appropriate to DPF applications.

Low emissions diesel fuel  

DOE Patents (OSTI)

A method and matter of composition for controlling NO.sub.x emissions from existing diesel engines. The method is achieved by adding a small amount of material to the diesel fuel to decrease the amount of NO.sub.x produced during combustion. Specifically, small amounts, less than about 1%, of urea or a triazine compound (methylol melamines) are added to diesel fuel. Because urea and triazine compounds are generally insoluble in diesel fuel, microemulsion technology is used to suspend or dissolve the urea or triazine compound in the diesel fuel. A typical fuel formulation includes 5% t-butyl alcohol, 4.5% water, 0.5% urea or triazine compound, 9% oleic acid, and 1% ethanolamine. The subject invention provides improved emissions in heavy diesel engines without the need for major modifications.

Five Myths About Diesel Engines Five Myths About Diesel Engines by Louise Lerner Steve Ciatti Steve Ciatti in the Engine Research Facility Diesel engines, long confined to trucks and ships, are garnering more interest for their fuel efficiency and reduced carbon dioxide emissions relative to gasoline engines. Argonne mechanical engineer Steve Ciatti takes a crack at some of the more persistent myths surrounding the technology. Myth #1: Diesel is dirty. "We all have this image of trucks belching out dirty black smoke," Ciatti said. This smoke is particulate matter from diesel exhaust: soot and small amounts of other chemicals produced by the engine. But EPA emissions requirements have significantly tightened, and diesel engines now have to meet the same criteria as gasoline engines. They do

IMPACT OF OXYGENATED FUEL ON DIESEL ENGINE PERFORMANCE AND EMISSIONS  

SciTech Connect

As evidenced by recent lawsuits brought against operators of large diesel truck fleets [1] and by the Consent Decree brought against the heavy-duty diesel manufacturers [2], the environmental and health effects of diesel engine emissions continue to be a significant concern. Reduction of diesel engine emissions has traditionally been achieved through a combination of fuel system, combustion chamber, and engine control modifications [3]. Catalytic aftertreatment has become common on modern diesel vehicles, with the predominant device being the diesel oxidation catalytic converter [3]. To enable advanced after-treatment devices and to directly reduce emissions, significant recent interest has focused on reformulation of diesel fuel, particularly the reduction of sulfur content. The EPA has man-dated that diesel fuel will have only 15 ppm sulfur content by 2007, with current diesel specifications requiring around 300 ppm [4]. Reduction of sulfur will permit sulfur-sensitive aftertreatment devices, continuously regenerating particulate traps, NOx control catalysts, and plasma assisted catalysts to be implemented on diesel vehicles [4]. Another method of reformulating diesel fuel to reduce emissions is to incorporate oxygen in the fuel, as was done in the reformulation of gasoline. The use of methyl tertiary butyl ether (MTBE) in reformulated gasoline has resulted in contamination of water resources across the country [5]. Nonetheless, by relying on the lessons learned from MTBE, oxygenation of diesel fuel may be accomplished without compromising water quality. Oxygenation of diesel fuel offers the possibility of reducing particulate matter emissions significantly, even for the current fleet of diesel vehicles. The mechanism by which oxygen content leads to particulate matter reductions is still under debate, but recent evidence shows clearly that ''smokeless'' engine operation is possible when the oxygen content of diesel fuel reaches roughly 38% by weight [6]. The potential improvements in energy efficiency within the transportation section, particularly in sport utility vehicles and light-duty trucks, that can be provided by deployment of diesel engines in passenger cars and trucks is a strong incentive to develop cleaner burning diesel engines and cleaner burning fuels for diesel engines. Thus, serious consideration of oxygenated diesel fuels is of significant practical interest and value to society. In the present work, a diesel fuel reformulating agent, CETANERTM, has been examined in a popular light-medium duty turbodiesel engine over a range of blending ratios. This additive is a mixture of glycol ethers and can be produced from dimethyl ether, which itself can be manufactured from synthesis gas using Air Products' Liquid Phase Dimethyl Ether (LPDME TM) technology. CETANERTM is a liquid, has an oxygen content of 36 wt.%, has a cetane number over 100 and is highly miscible in diesel fuel. This combination of physical and chemical properties makes CETANERTM an attractive agent for oxygenating diesel fuel. The present study considered CETANERTM ratios from 0 to 40 wt.% in a California Air Resources Board (CARB) specification diesel fuel. Particulate matter emissions, gaseous emissions and in-cylinder pressure traces were monitored over the AVL 8-Mode engine test protocol [7]. This paper presents the results from these measurements and discusses the implications of using high cetane number oxygenates in diesel fuel reformulation.

Development of Advanced Diesel Particulate Filtration Systems Development of Advanced Diesel Particulate Filtration Systems The U.S. Environmental Protection Agency regulations require that on-highway diesel vehicles have filtration systems to reduce tail-pipe soot emissions, known as particulate matter (PM). Diesel particulate filtration (DPF) systems are currently the most efficient at directly controlling PM. Argonne researchers, working with Corning, Inc., and Caterpillar, Inc., through a cooperative research and development agreement, are exploiting previously unavailable technology and research results on diesel PM filtration and regeneration processes, aiming to the technology transfer of advanced PM emission control to industry. Argonne's Research In operation of DPF systems, the filtration and regeneration of particulate emissions are the key processes to be controlled for high efficiency. Due to difficulties in accessing the micro-scaled structures of DPF membranes and monitoring particulate filtration and high-temperature thermal processes, however, research has been limited to macroscopic observation for the product.

Diesel and biodiesel exhaust particle effects on rat alveolar macrophages with in vitro exposure  

Science Journals Connector (OSTI)

Abstract Combustion emissions from diesel engines emit particulate matter which deposits within the lungs. Alveolar macrophages (AMs) encounter the particles and attempt to engulf the particles. Emissions particles from diesel combustion engines have been found to contain diverse biologically active components including metals and polyaromatic hydrocarbons which cause adverse health effects. However little is known about AM response to particles from the incorporation of biodiesel. The objective of this study was to examine the toxicity in Wistar Kyoto rat AM of biodiesel blend (B20) and low sulfur petroleum diesel (PDEP) exhaust particles. Particles were independently suspended in media at a range of 1–500 ?g mL?1. Results indicated B20 and PDEP initiated a dose dependent increase of inflammatory signals from AM after exposure. After 24 h exposure to B20 and PDEP gene expression of cyclooxygenase-2 (COX-2) and macrophage inflammatory protein 2 (MIP-2) increased. B20 exposure resulted in elevated prostaglandin E2 (PGE2) release at lower particle concentrations compared to PDEP. B20 and PDEP demonstrated similar affinity for sequestration of PGE2 at high concentrations, suggesting detection is not impaired. Our data suggests PGE2 release from AM is dependent on the chemical composition of the particles. Particle analysis including measurements of metals and ions indicate B20 contains more of select metals than PDEP. Other particle components generally reduced by 20% with 20% incorporation of biodiesel into original diesel. This study shows AM exposure to B20 results in increased production of PGE2 in vitro relative to diesel.

Comparison of blends of conventional diesel fuel and CRBO containing high levels of FFA in a DI diesel engine  

Science Journals Connector (OSTI)

This work attempts to analyse the ability of high free fatty acid (FFA) crude rice bran oil (CRBO) in replacing diesel partially in a compression ignition (CI) engine. It was observed that the delay period and the maximum rate of pressure rise for CRBO blends are lower than diesel and is almost inversely proportional to FFA content. Maximum heat release rate for CRBO blends are lower and occur earlier than that of diesel. CRBO blends require longer duration to release 90% of heat than diesel and it decreases with increase in FFA content of CRBO. When operating with CRBO blends, all emission parameters were decreased significantly with a marginal increase in CO emission than that of diesel without affecting the brake thermal efficiency of the engine. It is concluded that higher FFA of CRBO blends does not inhibit its ability to be utilised as a fuel in CI engines.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification Task 3: SOx/NOx/Hg Removal for Low Sulfur Coal  

SciTech Connect

The goal of this project was to develop a near-zero emissions flue gas purification technology for existing PC (pulverized coal) power plants that are retrofitted with oxycombustion technology. The objective of Task 3 of this project was to evaluate an alternative method of SOx, NOx and Hg removal from flue gas produced by burning low sulfur coal in oxy-combustion power plants. The goal of the program was to conduct an experimental investigation and to develop a novel process for simultaneously removal of SOx and NOx from power plants that would operate on low sulfur coal without the need for wet-FGD & SCRs. A novel purification process operating at high pressures and ambient temperatures was developed. Activated carbonâ??s catalytic and adsorbent capabilities are used to oxidize the sulfur and nitrous oxides to SO{sub 3} and NO{sub 2} species, which are adsorbed on the activated carbon and removed from the gas phase. Activated carbon is regenerated by water wash followed by drying. The development effort commenced with the screening of commercially available activated carbon materials for their capability to remove SO{sub 2}. A bench-unit operating in batch mode was constructed to conduct an experimental investigation of simultaneous SOx and NOx removal from a simulated oxyfuel flue gas mixture. Optimal operating conditions and the capacity of the activated carbon to remove the contaminants were identified. The process was able to achieve simultaneous SOx and NOx removal in a single step. The removal efficiencies were >99.9% for SOx and >98% for NOx. In the longevity tests performed on a batch unit, the retention capacity could be maintained at high level over 20 cycles. This process was able to effectively remove up to 4000 ppm SOx from the simulated feeds corresponding to oxyfuel flue gas from high sulfur coal plants. A dual bed continuous unit with five times the capacity of the batch unit was constructed to test continuous operation and longevity. Full-automation was implemented to enable continuous operation (24/7) with minimum operator supervision. Continuous run was carried out for 40 days. Very high SOx (>99.9%) and NOx (98%) removal efficiencies were also achieved in a continuous unit. However, the retention capacity of carbon beds for SOx and NOx was decreased from ~20 hours to ~10 hours over a 40 day period of operation, which was in contrast to the results obtained in a batch unit. These contradictory results indicate the need for optimization of adsorption-regeneration cycle to maintain long term activity of activated carbon material at a higher level and thus minimize the capital cost of the system. In summary, the activated carbon process exceeded performance targets for SOx and NOx removal efficiencies and it was found to be suitable for power plants burning both low and high sulfur coals. More efforts are needed to optimize the system performance.

Diesel Engine Alternatives  

SciTech Connect

There are basically three different modes of combustion possible for use in reciprocating engines. These include, diffusion burning, as occurs in current diesel engines, flame propagation combustion such as used in conventional SI engines, and homogeneous combustion such as is used in the SwRI HCCI engine. Diesel engines currently offer significant fuel consumption benefits relative to other powerplants for on and off road applications; however, costs and efficiency may become problems as the emissions standards become even more stringent. This presentation presents a discussion of the potentials of HCCI and flame propagation engines as alternatives to the diesel engines. It is suggested that as the emissions standards become more and more stringent, the advantages of the diesel may disappear. The potential for HCCI is limited by the availability of the appropriate fuel. The potential of flame propagation engines is limited by several factors including knock, EGR tolerance, high BMEP operation, and throttling. These limitations are discussed in the context of potential for improvement of the efficiency of the flame propagation engine.

Diesel Engine Idling Test  

SciTech Connect

In support of the Department of Energy’s FreedomCAR and Vehicle Technology Program Office goal to minimize diesel engine idling and reduce the consumption of millions of gallons of diesel fuel consumed during heavy vehicle idling periods, the Idaho National Laboratory (INL) conducted tests to characterize diesel engine wear rates caused by extended periods of idling. INL idled two fleet buses equipped with Detroit Diesel Series 50 engines, each for 1,000 hours. Engine wear metals were characterized from weekly oil analysis samples and destructive filter analyses. Full-flow and the bypass filter cartridges were removed at four stages of the testing and sent to an oil analysis laboratory for destructive analysis to ascertain the metals captured in the filters and to establish wear rate trends. Weekly samples were sent to two independent oil analysis laboratories. Concurrent with the filter analysis, a comprehensive array of other laboratory tests ascertained the condition of the oil, wear particle types, and ferrous particles. Extensive ferrogram testing physically showed the concentration of iron particles and associated debris in the oil. The tests results did not show the dramatic results anticipated but did show wear trends. New West Technologies, LLC, a DOE support company, supplied technical support and data analysis throughout the idle test.

Effect of E85 on RCCI Performance and Emissions on a Multi-Cylinder Light-Duty Diesel Engine - SAE World Congress  

SciTech Connect

This paper investigates the effect of E85 on load expansion and FTP modal point emissions indices under reactivity controlled compression ignition (RCCI) operation on a light-duty multi-cylinder diesel engine. A General Motors (GM) 1.9L four-cylinder diesel engine with the stock compression ratio of 17.5:1, common rail diesel injection system, high-pressure exhaust gas recirculation (EGR) system and variable geometry turbocharger was modified to allow for port fuel injection with gasoline or E85. Controlling the fuel reactivity in-cylinder by the adjustment of the ratio of premixed low-reactivity fuel (gasoline or E85) to direct injected high reactivity fuel (diesel fuel) has been shown to extend the operating range of high-efficiency clean combustion (HECC) compared to the use of a single fuel alone as in homogeneous charge compression ignition (HCCI) or premixed charge compression ignition (PCCI). The effect of E85 on the Ad-hoc federal test procedure (FTP) modal points is explored along with the effect of load expansion through the light-duty diesel speed operating range. The Ad-hoc FTP modal points of 1500 rpm, 1.0bar brake mean effective pressure (BMEP); 1500rpm, 2.6bar BMEP; 2000rpm, 2.0bar BMEP; 2300rpm, 4.2bar BMEP; and 2600rpm, 8.8bar BMEP were explored. Previous results with 96 RON unleaded test gasoline (UTG-96) and ultra-low sulfur diesel (ULSD) showed that with stock hardware, the 2600rpm, 8.8bar BMEP modal point was not obtainable due to excessive cylinder pressure rise rate and unstable combustion both with and without the use of EGR. Brake thermal efficiency and emissions performance of RCCI operation with E85 and ULSD is explored and compared against conventional diesel combustion (CDC) and RCCI operation with UTG 96 and ULSD.

Retail Diesel Fuel Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

Along with heating oil prices, the distillate supply squeeze has Along with heating oil prices, the distillate supply squeeze has severely impacted diesel fuel prices, especially in the Northeast. Retail diesel price data are available sooner than residential heating oil data. This graph shows that diesel prices turned the corner sometime after February 7 and are heading down. Retail diesel fuel prices nationally, along with those of most other petroleum prices, increased steadily through most of 1999. Prices jumped dramatically (by over 11 cents per gallon) in the third week of January, and rose 2 or more cents a week through February 7. The increases were much more rapid in the Northeast. From January 17 through February 7, diesel fuel prices in New England rose nearly 68 cents per gallon, or 47 percent. Prices in the Mid-Atlantic region rose about 58

Effects of diesel particle filter retrofits and accelerated fleet turnover  

NLE Websites -- All DOE Office Websites (Extended Search)

Effects of diesel particle filter retrofits and accelerated fleet turnover Effects of diesel particle filter retrofits and accelerated fleet turnover on drayage truck emissions at the port of Oakland Title Effects of diesel particle filter retrofits and accelerated fleet turnover on drayage truck emissions at the port of Oakland Publication Type Journal Article Year of Publication 2011 Authors Dallmann, Timothy R., Robert A. Harley, and Thomas W. Kirchstetter Journal Environmental Science & Technology Volume 45 Issue 24 Pagination 10773-10779 Abstract Heavy-duty diesel drayage trucks have a disproportionate impact on the air quality of communities surrounding major freight-handling facilities. In an attempt to mitigate this impact, the state of California has mandated new emission control requirements for drayage trucks accessing ports and rail yards in the state beginning in 2010. This control rule prompted an accelerated diesel particle filter (DPF) retrofit and truck replacement program at the Port of Oakland. The impact of this program was evaluated by measuring emission factor distributions for diesel trucks operating at the Port of Oakland prior to and following the implementation of the emission control rule. Emission factors for black carbon (BC) and oxides of nitrogen (NOx) were quantified in terms of grams of pollutant emitted per kilogram of fuel burned using a carbon balance method. Concentrations of these species along with carbon dioxide were measured in the exhaust plumes of individual diesel trucks as they drove by en route to the Port. A comparison of emissions measured before and after the implementation of the truck retrofit/replacement rule shows a 54 ± 11% reduction in the fleet-average BC emission factor, accompanied by a shift to a more highly skewed emission factor distribution. Although only particulate matter mass reductions were required in the first year of the program, a significant reduction in the fleet-average NOx emission factor (41 ± 5%) was observed, most likely due to the replacement of older trucks with new ones.

Coal-fueled diesel locomotive test  

SciTech Connect

The biggest challenges to the development of a commercially-acceptable coal-fueled diesel-electric locomotive are integrating all systems into a working unit that can be operated in railroad service. This involves mainly the following three systems: (1) the multi-cylinder coal-fueled diesel engine, (2) the locomotive and engine controls, and (3) the CWS fuel supply system. Consequently, a workable 12-cylinder coal-fueled diesel engine was considered necessary at this stage to evolve the required locomotive support systems, in addition to gaining valuable multi-cylinder engine operating experience. The CWS fuel used during this project was obtained from Otisca, Inc. (Syracuse, NY). It was prepared from micronized and deashed Kentucky Blue Gem coal to 49.0% coal loading by weight, with less than 1% ash and 5 micron mean diameter particle size. Its higher heating value was analyzed at approximately 34630 kJ/k. Anti-agglomerating additive Triton X-114 was added to the CWS at GE Transportation Systems at 2% of coal weight. The nature of the Otisca CWS fuel makes it inherently more difficult to store, pump, and inject than diesel fuel, since concepts which govern Newtonian or normally viscous liquids do not apply entirely to CWS. Otisca CWS tends to be unstable and to settle in tanks and lines after a period of time, making it necessary to provide a means of agitation during storage. To avoid long term settling problems and to minimize losses, piping velocities were designed to be in the 60-90 m/min range.

Experimental analysis of a diesel engine operating in Diesel–Ethanol Dual-Fuel mode  

Science Journals Connector (OSTI)

Abstract The use of engines is necessary to keep the world moving. Such engines are fed mainly by fossil fuels, among these, the diesel. The operation and the behavior of engines in different thermodynamic cycles, with common fossil fuels, it is still challenging but, in general, it has well known and documented data. On the other hand, for alternative fuels, there is still demand of experimental data, particularly considering that it is desirable, most of the times, the use of a system with dual mode (reversible). Such systems are called Dual-Fuel, it brings a greater degree of freedom, but imply in technological challenges. In this paper we used an engine operating with single cylinder direct injection diesel and port ethanol injection system in Dual-Fuel mode with a 100% electronically controlled calibration. The methodology applied was, once the engine calibration was given to achieve the best specific fuel consumption or the MBT (Maximum Brake Torque) in each load condition, to gradually substitute the diesel oil by ethanol in compliance with the requirements established. Comparisons were made among working conditions considering the rate of diesel substitution and the energy indicated efficiency. Initially, the flow structure in the combustion chamber was tested in both ‘quiescent’ and high “swirl” modes. Compression ratios were adjusted at 3 different levels: 14:1, 16:1 and 17:1. It was tested two injectors, the first one of 35 g/s and another of 45 g/s. Regarding pressure diesel injection, 4 levels were investigated namely 800, 1000, 1200 and 1400 bar.

Effect of hydrogen addition on criteria and greenhouse gas emissions for a marine diesel engine  

Science Journals Connector (OSTI)

Abstract Hydrogen remains an attractive alternative fuel to petroleum and a number of investigators claim that adding hydrogen to the air intake manifold of a diesel engine will reduce criteria emissions and diesel fuel consumption. Such claims are appealing when trying to simultaneously reduce petroleum consumption, greenhouse gases and criteria pollutants. The goal of this research was to measure the change in criteria emissions (CO, NOx, and PM2.5) and greenhouse gases such as carbon dioxide (CO2), using standard test methods for a wide range of hydrogen addition rates. A two-stroke Detroit Diesel Corporation 12V-71TI marine diesel engine was mounted on an engine dynamometer and tested at three out of the four loads specified in the ISO 8178-4 E3 emission test cycle and at idle. The engine operated on CARB ultra-low sulfur #2 diesel with hydrogen added at flow rates of 0, 22 and 220 SLPM. As compared with the base case without hydrogen, measurements showed that hydrogen injection at 22 and 220 SLPM had negligible influence on the overall carbon dioxide specific emission, EF CO 2 . However, in examining data at each load the data revealed that at idle EF CO 2 was reduced by 21% at 22 SLPM (6.9% of the added fuel energy was from hydrogen) and 37.3% at 220 SLPM (103.1% of the added fuel energy was from hydrogen). At all other loads, the influence of added hydrogen was insignificant. Specific emissions for nitrogen oxides, EF NO x , and fine particulate matters, EF PM 2.5 , showed a trade-off relationship at idle. At idle, EF NO x was reduced by 28% and 41% with increasing hydrogen flow rates, whilst EF PM 2.5 increased by 41% and 86% respectively. For other engine loads, EF NO x and EF PM 2.5 did not change significantly with varying hydrogen flow rates. One of the main reasons for the greater impact of hydrogen at idle is that the contribution of hydrogen to the total fuel energy is much higher at idle as compared to the other loads. The final examination in this paper was the system energy balance when hydrogen is produced by an on-board electrolysis unit. An analysis at 75% engine load showed that hydrogen production increased the overall equivalent fuel consumption by 2.6% at 22 SLPM and 17.7% at 220 SLPM.

Development of a fuel-tolerant diesel for alternative fuels  

Science Journals Connector (OSTI)

There is a growing requirement for engines operating on a wider range of fuels than when fuel supplies were more stable. The diesel engine, with its high compression ratio and absence of part-load throttling, offers high efficiency. Some widely available alternative fuels, in particular alcohol from biomass, present problems because of their low cetane number. The authors report the development of a diesel engine using a combustion system incorporating a high-energy, multi-strike spark to promote smooth combustion. Results obtained with this engine using ethanol are presented to illustrate its ability to handle fuels of very low cetane numbers.

Diesel emission control: Catalytic filters for particulate removal  

Science Journals Connector (OSTI)

The European diesel engine industry represents a vital sector across the Continent, with more than 2 million direct work positions and a turnover of over 400 billion Euro. Diesel engines provide large paybacks to society since they are extensively used to transport goods, services and people. In recent years increasing attention has been paid to the emissions from diesel engines which, like gasoline engine emissions, include carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx). Diesel engines also produce significant levels of particulate matter (PM), which consists mostly of carbonaceous soot and a soluble organic fraction (SOF) of hydrocarbons that have condensed on the soot.Meeting the emission levels imposed for NOx and PM by legislation (Euro IV in 2005 and, in the 2008 perspective, Euro V) requires the development of a number of critical technologies to fulfill these very stringent emission limits (e.g. 0.005 g/km for PM). This review is focused on these innovative technologies with special reference to catalytic traps for diesel particulate removal.

Steam bottoming cycle for an adiabatic diesel engine  

SciTech Connect

A study of steam bottoming cycles using adiabatic diesel engine exhaust heat projected substantial performance and economic benefits for long haul trucks. A parametric analysis of steam cycle and system component variables, system cost, size and performance was conducted. An 811 K/6.90 MPa state-of-the-art reciprocating expander steam system with a monotube boiler and radiator core condenser was selected for preliminary design. When applied to a NASA specified turbo-charged adiabatic diesel the bottoming system increased the diesel output by almost 18%. In a comparison of the costs of the diesel with bottoming system (TC/B) and a NASA specified turbocompound adiabatic diesel with after-cooling with the same total output, the annual fuel savings less the added maintenance cost was determined to cover the increased initial cost of the TC/B system in a payback period of 2.3 years. Also during this program steam bottoming system freeze protection strategies were developed, technological advances required for improved system reliability were considered and the cost and performance of advanced systems were evaluated.

Practical implications of marine diesel engine emission regulations  

SciTech Connect

The main pollutants from marine diesel engines are oxides of nitrogen (NOx), sulfur oxides (SOx) and particulates (soot). However, the proposed marine diesel engine emission regulations will primarily focus on the levels of NOx and SOx. In the future, once the proposed regulations are met, the limits and levels of other emissions will come under increasing scrutiny, such as particulates, hydrocarbons and carbon monoxide. Regardless of the type of pollutant, there are generally two classes of emission control: (1) techniques that reduce the amount of pollutant formed in the combustion process, or (2) prevent the pollutants from reaching the atmosphere. Unfortunately, some of these control techniques will not be able to meet the incoming regulations. Therefore, this paper identifies the diesel engine emissions of concern, the impending regulations, and the merits of current and future emission control technologies required to meet these regulations.

Effects of Fuel Physical Properties on Diesel Engine Combustion Using Diesel and Bio-Diesel Fuels  

SciTech Connect

A computational study is performed to investigate the effects of physical property on diesel engine combustion characteristics using bio-diesel fuels. Properties of typical bio-diesel fuels that were either calculated or measured are used in the study and the simulation results are compared with those of conventional diesel fuels. Sensitivity of the computational results to individual physical properties is also investigated, and the results can provide information for desirable characteristics of the blended fuels. The properties considered in this study include liquid density, vapor pressure, surface tension, liquid viscosity, liquid thermal conductivity, liquid specific heat, latent heat, vapor specific heat, vapor diffusion coefficient, vapor viscosity and vapor thermal conductivity. The results show significant effects of the fuel physical properties on ignition delay and burning rates at various engine operating conditions. It is seen that there is no single physical property that dominates differences of ignition delay between diesel and bio-diesel fuels. However, among the 11 properties considered in the study, the simulation results were found to be most sensitive to the liquid fuel density, vapor pressure and surface tension through their effects on the mixture preparation processes.

Precise instrumentation of a diesel single-cylinder research engine  

Science Journals Connector (OSTI)

The accuracy of any empirical result is a direct consequence of the quality of experimental setup and the strict control over testing conditions. For internal combustion engines, a large number of parameters that also exhibit complex interdependence may significantly affect the engine performance. Therefore, this work describes the essentials required to establish a high-quality diesel engine research laboratory. A single-cylinder diesel engine is taken as the fundamental building block and the requirements for all essential sub-systems including fuel, intake, exhaust, coolant and exhaust gas recirculation (EGR) are laid out. The measurement and analysis of cylinder pressure, and exhaust gas sampling/conditioning requirements for emission measurement are discussed in detail. The independent control of EGR and intake boost is also highlighted. The measurement and analysis techniques are supported with empirical data from a single-cylinder diesel engine setup. The emphasis is on providing the necessary guidelines for setting up a fully-instrumented diesel engine test laboratory.

Ethanol fuel for diesel tractors  

SciTech Connect

The use of ethanol fuel in turbocharged diesel tractors is considered. The investigation was performed to evaluate the conversion of a diesel tractor for dual-fueling with ethanol by attaching a carburetor to the inlet air system or with the use of an alcohol spray-injection kit. In this system the mixture of water and alcohol is injected into the air stream by means of pressure from the turbocharger. The carburetor was attached to a by-pass apparatus which allowed the engine to start and shut off on diesel alone. Approximately 46% of the energy for the turbocharged 65 kW diesel tractor could be supplied by carbureted ethanol, and about 30% by the spray-injection approach. Knock limited the extent of substitution of ethanol for diesel fuel. The dual-fueling with ethanol caused a slight increase in brake thermal efficiency. Exhaust temperatures were much lower for equivalent high torque levels. Maximum power was increased by 36% with the spray-injection approach and about 59% with carburetion.

A Clean Coal Diesel project was undertaken to demonstrate a new Clean Coal Technology that offers technical, economic and environmental advantages over conventional power generating methods. This innovative technology (developed to the prototype stage in an earlier DOE project completed in 1992) enables utilization of pre-processed clean coal fuel in large-bore, medium-speed, diesel engines. The diesel engines are conventional modern engines in many respects, except they are specially fitted with hardened parts to be compatible with the traces of abrasive ash in the coal-slurry fuel. Industrial and Municipal power generating applications in the 10 to 100 megawatt size range are the target applications. There are hundreds of such reciprocating engine power-plants operating throughout the world today on natural gas and/or heavy fuel oil.

Coal-fired diesel generator  

SciTech Connect

The objective of the proposed project is to test the technical, environmental, and economic viability of a coal-fired diesel generator for producing electric power in small power generating markets. Coal for the diesel generator would be provided from existing supplies transported for use in the University`s power plant. A cleanup system would be installed for limiting gaseous and particulate emissions. Electricity and steam produced by the diesel generator would be used to supply the needs of the University. The proposed diesel generator and supporting facilities would occupy approximately 2 acres of land adjacent to existing coal- and oil-fired power plant and research laboratory buildings at the University of Alaska, Fairbanks. The environmental analysis identified that the most notable changes to result from the proposed project would occur in the following areas: power plant configuration at the University of Alaska, Fairbanks; air emissions, water use and discharge, and the quantity of solid waste for disposal; noise levels at the power plant site; and transportation of coal to the power plant. No substantive adverse impacts or environmental concerns were identified in analyzing the effects of these changes.

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.

Unlike many multivariable controllers published in the literature, it requires neither an internal model nor identification algorithms. It has been designed considering the instrumentation set usually embedded in a mass-produced passenger car. Its rule-based structure has led to an algorithm, which is easy to implement. In comparison to controllers embedded at present in standard Engine Control Units (ECUs), it improves the trajectory tracking of desired outputs as noted during simulation of EURO cycles. In terms of robustness, this controller is little sensitive to the parameter disparity generally encountered in mass-produced engines.

Gasoline and Diesel Fuel Update  

Gasoline and Diesel Fuel Update (EIA)

Sampling Methodology Sampling Methodology The sample design for the weekly diesel price survey was a two-phase design. The first phase constituted construction of a frame of 2,207 company-State units (CSUs) from the combination of two sample cycles of the EIA-782A and EIA-782B surveys that collected monthly petroleum products' sales at the State level. For sampling purposes, any combination of State and company where diesel was sold through retail outlets as reported on the EIA-782 surveys defined a CSU, the sampling unit. For the second phase, a sub-sample of the 2,207 CSUs from phase 1 was selected using probability proportional to size (PPS). The measure of size for each of the two sample cycles separately was normalized using the annual State sales' volumes from the monthly survey divided by the unit's

Gasoline and Diesel Fuel Update  

Gasoline and Diesel Fuel Update (EIA)

Sampling Methodology Sampling Methodology The respondents reporting to the weekly diesel price survey represent a stratified probability proportional to size (PPS) sample selected from a frame list of retail outlets. The outlet sampling frame was constructed using commercially available lists from several sources in order to provide comprehensive coverage of truck stops and service stations that sell on-highway diesel fuel in the United States. The frame includes about 62,000 service stations and 4,000 truck stops. Due to statistical and operational considerations, outlets in the States of Alaska and Hawaii are excluded from the target population. The primary publication cells of the survey include Petroleum Administration for Defense Districts (PADDs) 2-4, three sub-PADDs within

Staged direct injection diesel engine  

DOE Patents (OSTI)

A diesel engine having staged injection for using lower cetane number fuels than No. 2 diesel fuel. The engine includes a main fuel injector and a pilot fuel injector. Pilot and main fuel may be the same fuel. The pilot injector injects from five to fifteen percent of the total fuel at timings from 20.degree. to 180.degree. BTDC depending upon the quantity of pilot fuel injected, the fuel cetane number and speed and load. The pilot fuel injector is directed toward the centerline of the diesel cylinder and at an angle toward the top of the piston, avoiding the walls of the cylinder. Stratification of the early injected pilot fuel is needed to reduce the fuel-air mixing rate, prevent loss of pilot fuel to quench zones, and keep the fuel-air mixture from becoming too fuel lean to become effective. In one embodiment, the pilot fuel injector includes a single hole for injection of the fuel and is directed at approximately 48.degree. below the head of the cylinder.

Coal-liquid fuel/diesel engine operating compatibility. Final report  

SciTech Connect

This work is intended to assess the possibilities of using coal-derived liquids (CDL) represented by a specific type (SRC II) and shale-derived distillate fuel in blends of petroleum-derived fuels in medium-speed, high-output, heavy-duty diesel engines. Conclusions are as follows: (1) Blends of solvent refined coal and diesel fuel may be handled safely by experienced diesel engine mechanics. (2) A serious corrosion problem was found in the fuel pump parts when operating with solvent refined coal blended with petroleum. It is expected that a metallurgy change can overcome this problem. (3) Proper selection of materials for the fuel system is required to permit handling coal-derived liquid fuels. (4) A medium speed, high horsepower, 4-cycle diesel engine can be operated on blends of solvent refined coal and petroleum without serious consequences save the fuel system corrosion previously mentioned. This is based on a single, short durability test. (5) As represented by the product evaluated, 100% shale-derived distillate fuel may be used in a medium speed, high horsepower, 4-cycle diesel engine without significant consequences. (6) The shale product evaluated may be blended with petroleum distillate or petroleum residual materials and used as a fuel for medium speed, high horsepower, 4-cycle diesel engines. 7 references, 24 figures, 20 tables.

An overview of utilizing water-in-diesel emulsion fuel in diesel engine and its potential research study  

Science Journals Connector (OSTI)

Abstract The need for more efficient energy usage and a less polluted environment are the prominent research areas that are currently being investigated by many researchers worldwide. Water-in-diesel emulsion fuel (W/D) is a promising alternative fuel that could fulfills such requests in that it can improve the combustion efficiency of a diesel engine and reduce harmful exhaust emission, especially nitrogen oxides (NOx) and particulate matter (PM). To date, there have been many W/D emulsion fuel studies, especially regarding performance, emissions and micro-explosion phenomena. This review paper gathers and discusses the recent advances in emulsion fuel studies in respect of the impact of W/D emulsion fuel on the performance and emission of diesel engines, micro-explosion phenomena especially the factors that affecting the onset and strength of micro-explosion process, and proposed potential research area in W/D emulsion fuel study. There is an inconsistency in the results reported from previous studies especially for the thermal efficiency, brake power, torque and specific fuel consumption. However, it is agreed by most of the studies that W/D does result in an improvement in these measurements when the total amount of diesel fuel in the emulsion is compared with that of the neat diesel fuel. \\{NOx\\} and PM exhaust gas emissions are greatly reduced by using the W/D emulsion fuel. Unburnt hydrocarbon (UHC) and carbon monoxide (CO) exhaust emissions are found to be increased by using the W/D emulsion fuel. The inconsistency of the experimental result can be related to the effects of the onset and the strength of the micro-explosion process. The factors that affect these measurements consist of the size of the dispersed water particle, droplet size of the emulsion, water-content in the emulsion, ambient temperature, ambient pressure, type and percentage of surfactant, type of diesel engine and engine operating conditions. Durability testing and developing the fuel production device that requires no/less surfactant are the potential research area that can be explored in future.

Pollution duality in turbocharged heavy duty diesel engine  

Science Journals Connector (OSTI)

Diesel engine designers are faced with increasingly stringent social demands to reduce emissions while maintaining high performance. Several strategies are considered, such as the advanced fuel system, the cooled exhaust gas recirculation (EGR), the particulate filter, the NOx after-treatment, the oxidation catalyst, the advanced control techniques and the alternative combustion. These strategies have been tuned to achieve the lowest engine exhaust gas emissions. The major problem of diesel engine pollution is the NOx and soot formation. Their antagonistic evolution according to the air/fuel ratio is well-known, and requires a good compromise. In this article, a numerical investigation was carried out using the KIVA-3v code. The aim deals with the influence of some engine parameters on the performances and the pollutant (NOx-soot) formation of a turbocharged heavy duty direct injection diesel engine. The numerical simulations were achieved to capture independently the effects of engine operating parameters such as the fuel injection timing, the fuel injection duration, the piston bowl diameter and the EGR rate. The obtained results are discussed and some conclusions are developed.

Fuel effects on flame lift-off under diesel conditions  

SciTech Connect

An apparent relation between the lift-off length under diesel conditions and the ignition quality of a fuel has previously been reported. To cast light on the underlying mechanism, the current study aims to separate flame lift-off effects of the chemical ignition delay from those of other fuel properties under diesel conditions. Flame lift-off was measured in an optical diesel engine by high-speed video imaging of OH-chemiluminescence. Fuel and ambient-gas properties were varied during the experiment. Only a weak correlation was found between ignition delay and lift-off length. The data indicate that this correlation is due to a common, stronger correlation with the ambient oxygen concentration. The chemical ignition delay and the fuel type had similar, weak effects on the lift-off length. A recently proposed mechanism for lift-off stabilization was used to interpret the results. It assumes that reactants approaching the lift-off position of the jet are mixed with high-temperature products found along the edges of the flame, which trigger autoignition. In this picture, the fuel effect is most likely due to differences in the amount of mixing with high-temperature products that is required for autoignition. In the current experiment, all lift-off effects seem to arise from variations in the reactant and product temperatures, induced by fuel and ambient properties. (author)

14 - Biodiesel and renewable diesel production methods  

Science Journals Connector (OSTI)

Abstract: Vegetable oils and animal fats have come to be recognized as important sources of renewable fuels. Fatty acid methyl esters are known as biodiesel, and are the leading source for non-petroleum diesel fuel. With hydrogenation and isomerization, oils and fats can be converted to renewable diesel and jet fuel that are drop-in replacements for petroleum diesel fuel and jet fuel. This chapter reviews the processes used to produce these fuels and the feedstocks that will provide the supplies of oils and fats needed to meet a growing world demand.

Conversion of a diesel engine to a spark ignition natural gas engine  

SciTech Connect

Requirements for alternatives to diesel-fueled vehicles are developing, particularly in urban centers not in compliance with mandated air quality standards. An operator of fleets of diesel- powered vehicles may be forced to either purchase new vehicles or equip some of the existing fleets with engines designed or modified to run on alternative fuels. In converting existing vehicles, the operator can either replace the existing engine or modify it to burn an alternative fuel. Work described in this report addresses the problem of modifying an existing diesel engine to operate on natural gas. Tecogen has developed a technique for converting turbocharged automotive diesel engines to operate as dedicated spark-ignition engines with natural gas fuel. The engine cycle is converted to a more-complete-expansion cycle in which the expansion ratio of the original engine is unchanged while the effective compression ratio is lowered, so that engine detonation is avoided. The converted natural gas engine, with an expansion ratio higher than in conventional spark- ignition natural gas engines, offers thermal efficiency at wide-open- throttle conditions comparable to its diesel counterpart. This allows field conversion of existing engines. Low exhaust emissions can be achieved when the engine is operated with precise control of the fuel air mixture at stoichiometry with a 3-way catalyst. A Navistar DTA- 466 diesel engine with an expansion ratio of 16.5 to 1 was converted in this way, modifying the cam profiles, increasing the turbocharger boost pressure, incorporating an aftercooler if not already present, and adding a spark-ignition system, natural gas fuel management system, throttle body for load control, and an electronic engine control system. The proof-of-concept engine achieved a power level comparable to that of the diesel engine without detonation. A conversion system was developed for the Navistar DT 466 engine. NOx emissions of 1.5 g/bhp-h have been obtained.

Flammability of diesel fuels with various compositions  

SciTech Connect

This paper reports on a study of the flammability of a number of fuels and blends, in relation to their physicochemical properties, particularly the volatility; these studies were performed in a specially designed simulator. The following fuels were used in the studies: a hydrotreated straight-run diesel fuel L; a catalytic gas oil; diesel fuel A; blends of diesel fuels L and A with cetaine, alpha-methylnaphthalene, undecane, and docosane; and a blend of fuel L, A-72 gasoline, and the additive TsGN. The physicochemical properties of the test fuels are shown. It is shown that the flammability of fuels with various compositions in a diesel engine is more correctly evaluated on the basis of the ignition delay period, which can be calculated from the cetane number and other physicochemical property indexes of fuels for a particular set of engine operating conditions.

Thermal barrier coatings application in diesel engines  

SciTech Connect

Commercial use of thermal barrier coatings in diesel engines began in the mid 70`s by Dr. Ingard Kvernes at the Central Institute for Industrial Research in Oslo, Norway. Dr. Kvernes attributed attack on diesel engine valves and piston crowns encountered in marine diesel engines in Norwegian ships as hot-corrosion attributed to a reduced quality of residual fuel. His solution was to coat these components to reduce metal temperature below the threshold of aggressive hot-corrosion and also provide protection. Roy Kamo introduced thermal barrier coatings in his `Adiabatic Diesel Engine` in the late 70`s. Kamo`s concept was to eliminate the engine block water cooling system and reduce heat losses. Roy reported significant performance improvements in his thermally insulated engine at the SAE Congress in 1982. Kamo`s work stimulates major programs with insulated engines, particularly in Europe. Most of the major diesel engine manufacturers conducted some level of test with insulated combustion chamber components. They initially ran into increased fuel consumption. The German engine consortium had Prof. Woschni of the Technical Institute in Munich. Woschni conducted testing with pistons with air gaps to provide the insulation effects. Woschni indicated the hot walls of the insulated engine created a major increase in heat transfer he refers to as `convection vive.` Woschni`s work was a major factor in the abrupt curtailment of insulated diesel engine work in continental Europe. Ricardo in the UK suggested that combustion should be reoptimized for the hot-wall effects of the insulated combustion chamber and showed under a narrow range of conditions fuel economy could be improved. The Department of Energy has supported thermal barrier coating development for diesel engine applications. In the Clean Diesel - 50 Percent Efficient (CD-50) engine for the year 2000, thermal barrier coatings will be used on piston crowns and possibly other components.

Dual-channel filter photometer system for biocomponent content determination in diesel oil  

Science Journals Connector (OSTI)

Currently, infrared spectrometry is the most often used method of determination of the biocomponent content in diesel oil, but this is also an expensive and time-consuming process. In this study, a portable, low-cost dual-channel filter photometer system is presented which meets the requirements of the European standard for biocomponent concentration measurements in diesel fuel. The results obtained using this novel system are reported and compared to the measurements made using a standard infrared spectrometer for biodiesel concentration between 0% and 20% by weight. The advantages of the new system, such as its adaptability to the different environmental conditions of analysis, are also discussed.

METC research on coal-fired diesels  

SciTech Connect

The METC in-house Coal-Fueled Diesel Research project is part of the overall DOE effort to develop a technology base for diesel engines capable of operating on coal, shale oil or low-cost coal-derived fuels. The in-house effort started in 1985 as a test-bed for coal-derived liquid fuels and will end this fiscal year with the successful completion of METC`s diesel R&D program. Currently METC in-house research and development efforts focus on pilot chamber combustion in METC`s coal-water slurry (CWS) fueled diesel engine. A novel pilot chamber for a direct-injected, coal-fueled diesel engine has been designed and is being tested in METC`s single cylinder research diesel engine. The pilot chamber configuration allows for operation at extended load and speed conditions using 100 percent CWS and no other pilot fuel. The concept involves the use of a small volume chamber exterior to the main cylinder in which approximately 5 percent of the total fuel energy at full load conditions is injected. Lower NO{sub X} levels may be obtained due to leaner burning as well as broader stable performance using only CWS fuel.

Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil  

Science Journals Connector (OSTI)

The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been carried out to examine properties, performance and emissions of different blends (B00, B20, B40, B60, B80 and B100) of PME comparison to diesel. A computer assisted single cylinder constant speed water cooled four stroke direct diesel engine (5 HP), which is commonly used in the agricultural sector for driving the pumps and small electrical generators is selected for the experimental investigation. The performance, emissions and combustion characteristics are analysed. The combustion parameters considered for this analysis are cylinder pressure and rate of heat release. The brake thermal efficiency is slightly reduced and hydrocarbon, carbon monoxide and smoke emissions in the exhaust are reduced when fuelled with methyl esters compared to diesel. But the NOx emissions are high when fuelled with methyl esters compared to diesel. [Received: December 11, 2009; Accepted: March 21, 2010

Recent Developments in BMW's Diesel Technology  

SciTech Connect

The image of BMW is very strongly associated to high power, sports biased, luxury cars in the premium car segment, however, particularly in the United States and some parts of Asia, the combination of a car in this segment with a diesel engine was up until now almost unthinkable. I feel sure that many people in the USA are not even aware that BMW produces diesel-powered cars. In Europe there is a completely contrary situation which, driven by the relative high fuel price, and the noticeable difference between gasoline and diesel prices, there has been a continuous growth in the diesel market since the early eighties. During this time BMW has accumulated more then 20 years experience in developing and producing powerful diesel engines for sports and luxury cars. BMW started the production of its 1st generation diesel engine in 1983 with a 2,4 l, turbocharged IDI engine in the 5 series model range. With a specific power of 35 kW/l, this was the most powerful diesel engine on the market at this time. In 1991 BMW introduced the 2nd generation diesel engine, beginning with a 2,5 l inline six, followed in 1994 by a 1,7 l inline four. All engines of this 2nd BMW diesel engine family were turbocharged and utilized an indirect injection combustion system. With the availability of high-pressure injection systems such as the common rail system, BMW developed its 3rd diesel engine family which consists of four different engines. The first was the 4-cylinder for the 3 series car in the spring of 1998, followed by the 6-cylinder in the fall of 1998 and then in mid 1999 by the worlds first V8 passenger car diesel with direct injection. Beginning in the fall of 2001 with the 4-cylinder, BMW reworked this DI engine family fundamentally. Key elements are an improved core engine design, the use of the common rail system of the 2nd generation and a new engine control unit with even better performance. Step by step, these technological improvements were introduce d to production for all members of this engine family and in all the different vehicle applications. In the next slide you can see the production volume of diesel engines by BMW. From the 1st family we produced {approx} 260,000 units over eight years and from the 2nd family {approx} 630,000 units were produced also during an eight year period. How successful the actual engine family with direct injection is can be seen in the increase of the production volume to 330,000 units for the year 2002 alone. The reason for this is that, in addition to the very low fuel consumption, this new engines provide excellent driving characteristics and a significant improvement in the level of noise and vibration. Page 2 of 5 In 2002, 26% of all BMW cars worldwide, and nearly 40% in Europe, were produced with a diesel engine under the hood. In the X5 we can see the biggest diesel success rate. Of all the X5 vehicles produced, 35% Worldwide and 68% in Europe are powered by a diesel engine.

The taxation of diesel cars in Belgium – revisited  

Science Journals Connector (OSTI)

This paper compares the current taxation of diesel and gasoline cars in Belgium with the guidelines for optimal taxation. We find that diesel cars are still taxed much less than gasoline cars, resulting in a dominant market share for diesel cars in the car stock. If the fuel tax is the main instrument to control for externalities and generate revenues, the diesel excise should be much higher than the excise on gasoline for two reasons: diesel is more polluting than gasoline and more importantly, through the better fuel efficiency, diesel cars contribute less fiscal revenues per mile.

Diesel Fuel Price Pass-through Diesel Fuel Price Pass-through EIA Home > Petroleum > Petroleum Feature Articles Diesel Fuel Price Pass-through Printer-Friendly PDF Diesel Fuel Price Pass-through by Michael Burdette and John Zyren* Over the past several years, the Energy Information Administration (EIA) has extensively studied the relationships between wholesale and retail markets for petroleum products. Beginning with gasoline, we looked at the two ends of the pricing structure in the U.S. market: daily spot prices, which capture sales of large quantities of product between refiners, importers/exporters, and traders; and weekly retail prices, measured at local gasoline outlets nationwide. In the course of this analysis, EIA has found that the relationships between spot and retail prices are consistent and predictable, to the extent that changes in spot prices can be used to forecast subsequent changes in retail prices for the appropriate regions. This article represents the extension of this type of analysis and modeling into the diesel fuel markets.

As the coatings result in higher available energy in the exhaust gas, efficiency gains are achieved through use of this energy by turbochargers, turbocompounding or thermoelectric generators.

Simulating Study of Premixed Charge Compression Ignition on Light-Duty Diesel Fuel Economy and Emissions Control  

SciTech Connect

We utilize the Powertrain Systems Analysis Toolkit (PSAT) combined with transient engine and aftertreatment component models to simulate the impact of premixed charge compression ignition (PCCI) on the fuel economy and emissions of light-duty (LD) diesel-powered conventional and hybrid electric vehicles (HEVs). Our simulated aftertreatment train consists of a diesel oxidation catalyst (DOC), lean NOx trap (LNT), and catalyzed diesel particulate filter (DPF). The results indicate that utilizing PCCI combustion significantly reduces fuel consumption and tailpipe emissions for the conventional diesel-powered vehicle with NOx and particulate emissions controls. These benefits result from a favorable engine speed-load distribution over the cycle combined with a corresponding reduction in the need to regenerate the LNT and DPF. However, the current PCCI technology appears to offer less potential benefit for diesel HEVs equipped with similar emissions controls. This is because PCCI can only be activated over a relatively small part of the drive cycle. Thus we conclude that future utilization of PCCI in diesel HEVs will require significant extension of the available speed-load range for PCCI and revision of current HEV engine management strategies before significant benefits can be realized.

Dual-fueling turbocharged diesels with ethanol  

SciTech Connect

Spray addition and carburetion methods were tested for dual-fueling a turbocharged, 65 kW diesel tractor. Approximately 30 percent of the fuel energy for the tractor was supplied by spraying ethanol into the intake air and about 46 percent by carburetion with little affect on the engine thermal efficiency. Further substitution of diesel fuel with ethanol was limited by knock. As the amount of ethanol fed into the engine was increased, ignition apparently changed from the steady burning process which normally occurs in a diesel engine to a rapid explosion which caused knock. The best fuel for the spray approach was a 50 percent ethanol/water solution and with the carburetor it was an 80 percent ethanol/water solution. (Refs. 6).

Effect of two-stage injection on combustion and emissions under high EGR rate on a diesel engine by fueling blends of diesel/gasoline, diesel/n-butanol, diesel/gasoline/n-butanol and pure diesel  

Science Journals Connector (OSTI)

Abstract The effect of two-stage injection on combustion and emission characteristics under high EGR (46%) condition were experimentally investigated. Four different fuels including pure diesel and blended fuels of diesel/gasoline, diesel/n-butanol, diesel/gasoline/n-butanol were tested. Results show that blending gasoline or/and n-butanol in diesel improves smoke emissions while induces increase in maximum pressure rise rate (MPRR). Adopting pilot injection close to main injection can effectively reduce the peak of premixed heat release rate and MPRR. However, for fuels blends with high percentage of low cetane number fuel, the effect of pilot fuel on ignition can be neglected and the improvement of MPRR is not that obvious. Pilot-main interval presents more obvious effect on smoke than pilot injection rate does, and the smoke emissions decrease with increasing pilot-main interval. A longer main-post interval results in a lower post heat release rate and prolonged combustion duration. While post injection rate has little effect on the start of ignition for post injection. The variation in fuel properties caused by blending gasoline or/and n-butanol into diesel does not impose obvious influence on post combustion. The smoke emission increases first and then declines with retard of post injection timing. Compared to diesel, the smoke emissions of blended fuels are more sensitive to the variation of post injection strategy.

The Chemistry of the Thermal DeNOx Process: A Review of the Technology's Possible Application to control of NOx from Diesel Engines  

SciTech Connect

This paper presents a review of the Thermal DeNOx process with respect to its application to control of NOx emissions from diesel engines. The chemistry of the process is discussed first in empirical and then theoretical terms. Based on this discussion the possibilities of applying the process to controlling NOx emissions from diesel engines is considered. Two options are examined, modifying the requirements of the chemistry of the Thermal DeNOx process to suit the conditions provided by diesel engines and modifying the engines to provide the conditions required by the process chemistry. While the former examination did not reveal any promising opportunities, the latter did. Turbocharged diesel engine systems in which the turbocharger is a net producer of power seem capable of providing the conditions necessary for NOx reduction via the Thermal DeNOx reaction.

Exhaust gas recirculation for advanced diesel combustion cycles  

Science Journals Connector (OSTI)

Abstract Modern diesel engines tend to utilize significantly large quantities of exhaust gas recirculation (EGR) and high intake pressures across the engine load range to meet \\{NOx\\} targets. At such high EGR rates, the combustion process and exhaust emissions tend to exhibit a marked sensitivity to small changes in the EGR quantity, resulting in unintended deviations from the desired engine performance characteristics (energy efficiency, emissions, stability). An accurate estimation of EGR and its effect on the intake dilution are, therefore, necessary to enable its application during transient engine operation or unstable combustion regimes. In this research, a detailed analysis that includes estimation of the transient (cycle-by-cycle) build-up of EGR and the time (engine cycles) required to reach the steady-state EGR operation has been carried out. One-step global equations to calculate the transient and steady-state gas concentrations in the intake and exhaust are proposed. The effects of engine load and intake pressure on EGR have been examined and explained in terms of intake charge dilution and in-cylinder excess-air ratio. The EGR analysis is validated against a wide range of empirical data that include low temperature combustion cycles, intake pressure and load sweeps. This research intends to not only formulate a clear understanding of EGR application for advanced diesel combustion but also to set forth guidelines for transient analysis of EGR.

The influence of propylene glycol ethers on base diesel properties and emissions from a diesel engine  

Science Journals Connector (OSTI)

Abstract The oxygenated additives propylene glycol methyl ether (PGME), propylene glycol ethyl ether (PGEE), dipropylene glycol methyl ether (DPGME) were studied to determine their influence on both the base diesel fuel properties and the exhaust emissions from a diesel engine (CO, NOx, unburnt hydrocarbons and smoke). For diesel blends with low oxygen content (?4.0 wt.%), the addition of these compounds to base diesel fuel decreases aromatic content, kinematic viscosity, cold filter plugging point and Conradson carbon residue. Also, each compound modifies the distillation curve at temperatures below the corresponding oxygenated compound boiling point, the distillate percentage being increased. The blend cetane number depends on the type of propylene glycol ether added, its molecular weight, and the oxygen content of the fuel. The addition of PGME decreased slightly diesel fuel cetane number, while PGEE and DPGME increased it. Base diesel fuel-propylene glycol ether blends with 1.0 and 2.5 wt.% oxygen contents were used in order to determine the performance of the diesel engine and its emissions at both full and medium loads and different engine speeds (1000, 2500 and 4000 rpm). In general, at full load and in comparison with base diesel fuel, the blends show a slight reduction of oxygen-free specific fuel consumption. CO emissions are reduced appreciably for 2.5 wt.% of oxygen blends, mainly for PGEE and DPGME. \\{NOx\\} emissions are reduced slightly, but not the smoke. Unburnt hydrocarbon emissions decrease at 1000 and 2500 rpm, but not at 4000 rpm. At medium load, the effect of the additives is much less significant, due to the fact that the ratio oxygen from additive/oxygen from air is much lower.

Utilization of alternative fuels in diesel engines  

SciTech Connect

The important findings for a 41-month research grant entitled The Utilization of Alternate Fuels in Diesel Engines are summarized. The procedure followed was to collect performance and emission data for various candidate alternate fuels and compare these data to that for a certified petroleum-based number two Diesel fuel oil. The method of test-fuel introduction was either via fumigation or to use the engine stock injection system. Results for methanol, ethanol, four vegetable oils, two shale-derived oils, and two coal-derived oils are reported. Based upon this study, alcohol fumigation does not appear to be a practical method for utilizing low combustion quality fuels in a Diesel engine. The reasons being, the need for a complex fuel management system and a narrow operating range bounded by wet misfire on the low load end and by severe knock at medium to high loads. Also, it was misfire on the low load end and by severe knock at medium to high loads. Also, it was found that alcohol fumigation enhances the bioactivity of the emitted exhaust particles. Finally, this study showed that while it is possible to inject many synthetic fuels using the engine stock injection system, wholly acceptable performance is only obtained from a fuel whose specifications closely approach those of a finished petroleum-based Diesel oil.

Caterpillar Light Truck Clean Diesel Program  

SciTech Connect

In 1998, light trucks accounted for over 48% of new vehicle sales in the U.S. and well over half the new Light Duty vehicle fuel consumption. The Light Truck Clean Diesel (LTCD) program seeks to introduce large numbers of advanced technology diesel engines in light-duty trucks that would improve their fuel economy (mpg) by at least 50% and reduce our nation's dependence on foreign oil. Incorporating diesel engines in this application represents a high-risk technical and economic challenge. To meet the challenge, a government-industry partnership (Department of Energy, diesel engine manufacturers, and the automotive original equipment manufacturers) is applying joint resources to meet specific goals that will provide benefits to the nation. [1] Caterpillar initially teamed with Ford Motor Company on a 5 year program (1997-2002) to develop prototype vehicles that demonstrate a 50% fuel economy improvement over the current 1997 gasoline powered light truck vehicle in this class while complying with EPA's Tier II emissions regulations. The light truck vehicle selected for the demonstration is a 1999 Ford F150 SuperCab. To meet the goals of the program, the 4.6 L V-8 gasoline engine in this vehicle will be replaced by an advanced compression ignition direct injection (CIDI) engine. Key elements of the Caterpillar LTCD program plan to develop the advanced CIDI engine are presented in this paper.

Assessment of the use of oxygenated fuels on emissions and performance of a diesel engine  

Science Journals Connector (OSTI)

Abstract Requirements as torque, power, specific fuel consumption and emitted compounds are highly influenced by the chemical composition of the fuel being burned. Thus, the aim of this study was to assess the use of oxygenated fuels on emissions of NOx, CO, HC, CO2 and particle number and size distribution (11.5 diesel engine coupled to a dynamometer bench was used, where three types of fuels were employed, B5 (diesel with 5% of biodiesel); B5E6 (ternary composition containing 89% diesel, 5% of biodiesel and 6% of ethanol); and B100 (100% of biodiesel). The performance of a diesel engine was also evaluated to see the impact of the oxygenated fuels in this kind of engine. The use of ethanol with high latent heat of vaporization and low cetane number added to the binary blend (B5) shown an increase in the HC emissions and a reduction in \\{NOx\\} emissions when compared to B5. The use of pure biodiesel (B100) with high oxygen content showed a reduction in the HC emissions, but presented the highest emissions for both \\{NOx\\} and particle number of smaller diameter among the studied fuels. The use of more oxygenated fuels reduced the power output and increased the fuel consumption, but the exergy analysis showed that the energy efficiency of these fuels could be considered similar to the B5 fuel.

Novel injector techniques for coal-fueled diesel engines. Final report  

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.

The effect of porosity on the mechanical properties of cordierite diesel particulate filter substrates  

SciTech Connect

Diesel particulate filter (DPF) technology depends on porous ceramic structures that trap the particulate matter in the diesel engine exhaust gas stream. The design of DPFs requires balancing the functional requirement of soot filtration with the mechanical properties and both are influenced by the porosity of the substrate. In addition, increasing the porosity of the substrate can assist with the catalytic washcoating, engine back pressure and engine efficiency. The effect of porosity on the elastic and fracture mechanical properties of cordierite based ceramic particulate filters was examined and will be described. Elastic modulus of DPF substrates was determined using resonant ultrasound spectroscopy while fracture toughness was characterized using the double-torsion test method. The interrelationships among specimen thickness, wall orientation, porosity and mechanical properties of the filter substrates will be discussed. A materials selection procedure to obtain filters with high thermal shock resistance and optimal mechanical properties will be described.

Therefore diesel engines entered vehicle segments where the expectations on the sound quality are exceptionally high. Sound quality and fuel efficiency are often conflicting goals during the development of a diesel engine. The typical sound character of diesel engines the so called Dieselness is an indicator for the overall sound quality of the vehicle noise. Hence it is desirable to rate the Dieselness of engine sounds. Sounds emitted by gasoline- and diesel-powered vehicles in idle condition were rated in psychoacoustic experiments using different methods. First the method of line length was used as direct scaling procedure to get ratio ratings of the relative Dieselness of the vehicle noises. Second a direct ranking of the noises has been done with the Random Access method where subjects had to rank the sounds according to their Dieselness. Third in a paired-comparison test the participants had to judge which of two sounds had more Dieselness resulting in an indirect scaling. These methods are compared regarding the time the experiments took and the resulting ranking respectively scaling. In addition a semantic differential test with general adjective pairs was conducted.

A Waste Heat Recovery System for Light Duty Diesel Engines  

SciTech Connect

In order to achieve proposed fuel economy requirements, engines must make better use of the available fuel energy. Regardless of how efficient the engine is, there will still be a significant fraction of the fuel energy that is rejected in the exhaust and coolant streams. One viable technology for recovering this waste heat is an Organic Rankine Cycle. This cycle heats a working fluid using these heat streams and expands the fluid through a turbine to produce shaft power. The present work was the development of such a system applied to a light duty diesel engine. This lab demonstration was designed to maximize the peak brake thermal efficiency of the engine, and the combined system achieved an efficiency of 44.4%. The design of the system is discussed, as are the experimental performance results. The system potential at typical operating conditions was evaluated to determine the practicality of installing such a system in a vehicle.

Surfactant screening of diesel-contaminated soil  

SciTech Connect

At one installation, approximately 60,000 gal of No. 2 diesel fuel leaked into the subsurface environment, with contamination at depths of 6 to 34 m below the surface. Argonne National Laboratory was contracted to perform treatability studies for site remediation. The treatability studies focused on four separate phases: (1) leachability studies on the various contaminated soil borings, (2) air stripping studies, (3) bioremediation studies, and (4) surfactant screening/surfactant flooding studies. This paper summarizes the fourth phase of the research program in which twenty-one surfactants were screened for possible use to mobilize the organics from the contaminated soil prior to bioremediation. Anionic surfactants resulted in the greatest degree of diesel mobilization. The most promising surfactants will be employed on actual contaminated soil samples obtained from the site. 18 refs., 16 figs., 1 tab.

Integrated design of diesel hydrotreating processes  

Science Journals Connector (OSTI)

This work presents an integrated approach for the design of diesel hydrotreating processes employing a simulated annealing optimisation algorithm. The modelling of reactor, separation and heat recovery system for diesel hydrotreating processes is discussed, and a novel optimisation framework is developed for the design of complex refinery processes. A comparison with conventional approach to process design, i.e. sequential evolution of design, is given to illustrate the ability of proposed approach to obtain overall hydrotreating process designs with minimum total annualised costs. The proposed integrated approach takes into account the trade-offs between capital and operating costs, as well as interactions between the hydrotreater, distillation column, and the associated heat exchanger network.

Utiization of alternate fuels in diesel engines  

SciTech Connect

Accomplishments during three years entitled The Utilization of Alternate Fuels in Diesel Engines are summarized. Experiments were designed and test equipment set-up for the purpose of evaluating the use of methanol as a fumigant for light-duty Diesel engine service. The major experimental results were obtained from a multicylinder automotive Diesel engine. However, fundamental studies employing a GC/micro-reactor and a constant volume combustion bomb were also started. The purpose of this work was to measure some of the chemical and physical properties of methanol and methanol-air mixtures. The laminar flame velocity for various mixtures has been measured in the combustion bomb and thermal degradation studies have begun in the GC/micro-reactor. An Oldsmobile 5.7 liter V/8 Diesel engine was fumigated with methanol in amounts up to 40% of the fuel energy. The primary objectives of the study were to determine the effect of methanol fumigation on fuel efficiency, smoke, nitric oxide emission, and the occurrence of severe knock. An assessment of the biological activity for samples of the raw exhaust particulate and its soluble organic extract was also made using boh the Ames Salmonella typhimurium test and the B. subtilis Comptest. Generally, methanol fumigation was found to decrease NO emission for all conditions, to have a slight effect on smoke opacity, and to have a beneficial effect on fuel efficiency at higher loads. Also at higher loads, the methanol was found to induce what was defined as knock limited operation. The biological activity of the raw particulate matter was fond to be less than that of its soluble organic extract. However, for both the fumigation of methanol did enhance the biological activity.

Effect of palm methyl ester-diesel blends performance and emission of a single-cylinder direct-injection diesel engine  

Science Journals Connector (OSTI)

The purpose of this study is to investigate engine performance and exhaust emission when using several blends of neat palm oil methyl ester (POME) with conventional diesel (D2) in a small direct injection diesel engine and to compare the outcomes to that of the D2 fuel. Engine performances exhaust emissions and some other important parameters were observed as a function of engine load and speed. In addition the effect of modifying compression ratio was also carried out in this study. From the engine experimental work neat and blended fuels behaved comparably to diesel (D2) in terms of fuel consumption thermal efficiency and rate of heat released. Smoke density showed better results than that emitted by D2 operating under similar conditions due to the presence of inherited oxygen and lower sulphur content in the biofuel and its blends. The emissions of CO CO2 and HC were also lower using blended mixtures and in its neat form. However NOx concentrations were found to be slight higher for POME and its blends and this was largely due to higher viscosity of POME and possibly the presence of nitrogen in the palm methyl ester. General observation indicates that biofuel blends can be use without many difficulties in this type of engine but for optimized operation minor modifications to the engine and its auxiliaries are required.

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.
