    Regulated and unregulated emissions (individual hydrocarbons, ethanol, aldehydes and ketones, polynuclear aromatic hydrocarbons (PAH), nitro-PAH, and soluble organic fraction of particulate matter) were characterized in engines utilizing duplicate ISO 8178-C1 eight-mode tests and FTP smoke tests. Certification No. 2 diesel (400 ppm sulfur) and three ethanol/diesel blends, containing 7.7 percent, 10 percent, and 15 percent ethanol, respectively, were used. The three, Tier II, off-road engines were 6.8-L, 8.1-L, and 12.5-L in displacement and each had differing fuel injection system designs. It was found that smoke and particulate matter emissions decreased with increasing ethanol content. Changes to the emissions of carbon monoxide and oxides of nitrogen varied with engine design, with some increases and some decreases. As expected, increasing ethanol concentration led to higher emissions of acetaldehyde (increases ranging from 27 to 139 percent). Benzene emissions were reduced by up to 50 percent with the ethanol-blended fuels. Emissions of 1,3-butadiene were also substantially decreased, with reductions ranging from 24 to 82 percent. Isolated trends were noted for certain PAHs. There was a decrease in 1-nitropyrene with use of ethanol in all cases. Particulate phase 1-nitropyrene was reduced from 18 to 62 percent. There was also a general increase in the proportion of heavy PAHs in the particulate phase with ethanol use, and although less pronounced, a general decrease in light PAHs in the particulate phase.

  4. Transport and intracellular accumulation of acetaldehyde in Saccharomyces cerevisiae

    The rate of acetaldehyde efflux from yeast cells and its intracellular concentration were studied in the light of recent suggestions that acetaldehyde inhibition may be an important factor in yeast ethanol fermentations. When the medium surrounding cells containing ethanol and acetaldehyde was suddenly diluted, the rate of efflux of acetaldehyde was slow relative to the rate of ethanol efflux, suggesting that acetaldehyde, unlike ethanol, may accumulate intracellularly. Intracellular acetaldehyde concentrations were measured during high cell density fermentations, using direct injection gas chromatography to avoid the need to concentrate or disrupt the cells. Intracellular acetaldehyde concentrations substantially exceeded the extracellular concentrations throughout fermentation and were generally much higher than the acetaldehyde concentrations normally recorded in the culture broth in ethanol fermentations. The technique used was sensitive to the time taken to cool and freeze the samples. Measured intracellular acetaldehyde concentrations fell rapidly as the time taken to freeze the suspensions was extended beyond 2 s. The results add weight to recent claims that acetaldehyde toxicity is responsible for some of the effects previously ascribed to ethanol in alcohol fermentations, especially Zymomonas fermentations. Further work is required to confirm the importance of acetaldehyde toxicity under other culture conditions.

    1997-01-05

    The lag phase of Saccharomyces cerevisiae subjected to a step increase in temperature or ethanol concentration was reduced by as much as 60% when acetaldehyde was added to the medium at concentrations less than 0.1 g/L. Maximum specific growth rates were also substantially increased. Even greater proportional reductions in lag time due to acetaldehyde addition were observed for ethanol-shocked cultures of Zymomonas mobilis. Acetaldehyde had no effect on S. cerevisiae cultures started from stationary phase inocula in the absence of environmental shock and its lag-reducing effects were greater in complex medium than in a defined synthetic medium. Acetaldehyde reacted strongly with the ingredients of complex culture media. It is proposed that the effect of added acetaldehyde may be to compensate for the inability of cells to maintain transmembrane acetaldehyde gradients following an environmental shock.

    A novel theoretical framework for predicting the branching between roaming and bond fission channels in molecular dissociations is described and applied to the decomposition of acetaldehyde. This reduced dimensional trajectory (RDT) approach, which is motivated by the long-range nature of the roaming, bond fission, and abstraction dynamical bottlenecks, involves the propagation of rigid-body trajectories on an analytic potential energy surface. The analytic potential is obtained from fits to large-scale multireference ab initio electronic structure calculations. The final potential includes one-dimensional corrections from higher-level electronic structure calculations and for the effect of conserved mode variations along both the addition and abstraction paths. The corrections along the abstraction path play a significant role in the predicted branching. Master equation simulations are used to transform the microcanonical branching ratios obtained from the RDT simulations to the temperature- and pressure-dependent branching ratios observed in thermal decomposition experiments. For completeness, a transition-state theory treatment of the contributions of the tight transition states for the molecular channels is included in the theoretical analyses. The theoretically predicted branching between molecules and radicals in the thermal decomposition of acetaldehyde is in reasonable agreement with the corresponding shock tube measurement described in the companion paper. The prediction for the ratio of the tight to roaming contributions to the molecular channel also agrees well with results extracted from recent experimental and experimental/theoretical photodissociation studies.

    A highly rated turbocharged diesel engine adapted for an alternative fuel based on ethanol and hexyl nitrate has been investigated with respect to the emission of organic compounds in the exhausts. The adaption involves: ignition nozzles with larger holes, a change of injection timing and more fuel injected per stroke. Emissions were measured at four different driving modes ie, 1, 8, 10 and 12 respectively, in the California Cycle. The exhaust composition are different compared to conventional diesel emissions. The main part of the organic pollutants consists of unburned ethanol and hexyl nitrate, acetaldehyde being the most abundant aldehyde.

    We report on studies of degradation mechanisms of tetraphenyl butadiene (TPB) coatings of the type used in neutrino and dark matter liquid argon experiments. Using gas chromatography coupled to mass spectrometry we have detected the ultraviolet-blocking impurity benzophenone (BP). We monitored the drop in performance and increase of benzophenone concentration in TPB plates with exposure to ultraviolet (UV) light, and demonstrate the correlation between these two variables. Based on the presence and initially exponential increase in the concentration of benzophenone observed, we propose that TPB degradation is a free radical-mediated photooxidation reaction, which is subsequently confirmed by displaying delayed degradation using a free radical inhibitor. Finally we show that the performance of wavelength-shifting coatings of the type envisioned for the LBNE experiment can be improved by 10-20%, with significantly delayed UV degradation, by using a 20% admixture of 4-tert-Butylcatechol.

    Tetraphenyl-butadiene (TPB) is a widely used fluorescent wavelength-shifter. A common application is in liquid-argon-based particle detectors, where scintillation light is produced in the UV at 128 nm. In liquid argon experiments, TPB is often employed to shift the scintillation light to the visible range in order to allow detection via standard photomultiplier tubes. This paper presents studies on the stability of TPB with time under exposure to light. We also examine batch-to-batch variations. We compare scintillation-grade TPB to 99% pure TPB response. In the 99% pure samples, we report a yellowing effect, and full degradation of the TPB emission-peak, upon extended exposure to light.

    In line with the study presented in the part I of this paper, the structure of a laminar rich premixed methane flame doped with 1,3-butadiene has been investigated. The flame contains 20.7% (molar) of methane, 31.4% of oxygen and 3.3% of 1,3-butadiene, corresponding to an equivalence ratio of 1.8, and a ratio C4H6 / CH4 of 16 %. The flame has been stabilized on a burner at a pressure of 6.7 kPa using argon as dilutant, with a gas velocity at the burner of 36 cm/s at 333 K. The temperature ranged from 600 K close to the burner up to 2150 K. Quantified species included usual methane C0-C2 combustion products and 1,3-butadiene, but also propyne, allene, propene, propane, 1,2-butadiene, butynes, vinylacetylene, diacetylene, 1,3-pentadiene, 2-methyl-1,3-butadiene (isoprene), 1-pentene, 3-methyl-1-butene, benzene and toluene. In order to model these new results, some improvements have been made to a mechanism previously developed in our laboratory for the reactions of C3-C4 unsaturated hydrocarbons. The main reacti...

The goal of this experiment was to investigate and demonstrate the potential of diesel engines for hybrid electric vehicles (HEVs) in a fuel economy and emissions. The test set-up consisted of a diesel engine coupled to an electric motor driving a Continuously Variable Transmission (CVT). This hybrid drive is connected to a dynamometer and a DC electrical power source creating a vehicle context by combining advanced computer models and emulation techniques. The experiment focuses on the impact of the hybrid control strategy on fuel economy and emissions-in particular, nitrogen oxides (NO{sub x}) and particulate matter (PM). The same hardware and test procedure were used throughout the entire experiment to assess the impact of different control approaches.

    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.

  16. DIESEL FUEL LUBRICATION

    SciTech Connect (OSTI)

    Qu, Jun [ORNL

    2012-01-01

    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.

    The papers in this volume deal in the main with the two most common forms of aftertreatment technology. The first is the trap oxidizer, which is a system for trapping and filtering the particulate matter from the exhaust gas and periodically removing it by thermal oxidation. This process is commonly known as regeneration. The second is the diesel oxidation catalyst. Similar in many ways to the flow through a converter in passenger cars, it oxidizes the soluble organic fraction of the diesel exhaust as well as gaseous hydrocarbons and carbon monoxide. This catalyst is being used in production volumes in heavy duty trucks in the US beginning in 1994. Several papers in this volume deal with the development experience of this converter application. There also is included a series of papers by trap and filter manufacturers dealing with improved materials, making their devices more durable. Papers have been processed separately for inclusion on the data base.

  1. Assessment of the Electrohol process to manufacture acetaldehyde from ethanol electrogeneratively. Final report

    SciTech Connect (OSTI)

    Trevino, A.A.

    1985-04-10

    Preliminary process economics data for the electrogenerative process to manufacture acetaldehyde from ethanol were generated based on patent information. The technology was assessed in four alternative processing options. The Electrohol process is viable in the US only if integrated to the production of 190 pf ethanol from corn in a large scale unit. To be competitive, the Electrohol process must show yields in excess of 93%. Its attractiveness depends on corn prices remaining under $2.90/bu and DDG selling for more than $132/T. A corn price of $2.00/bu is needed to make a farm-size corn-based processing alternative competitive. A plant based on the fermentation of molasses proved too expensive under the US economic assumptions. The Electrohol technology based on purchased ethanol cannot compete with the existing ethylene-based process under current conditions. To become attractive, the Electrohol process must have access to cheap ethanol ($1.43/gal). The zero electricity generation mode is the most attractive mode of operation for the Electrohol technology in the US. The penalty for low levels of generation (0.130 kwh/kg AcH) is, however, negligible. The optimum operating mode in W. Europe is the generation of 0.312 kwh/kg AcH. In Japan, the low generation level is perferred (0.130 kwh/kg AcH). In general, higher energy prices improve the competitiveness of the Electrohol processing alternatives.

  1. Diesel fuel from biomass

    SciTech Connect (OSTI)

    Kuester, J.L.

    1984-01-01

    A project to convert various biomass materials to diesel type transportation fuel compatible with current engine designs and the existing distribution system is described. A continuous thermochemical indirect liquefaction approach is used. The system consists of a circulating solid fluidized bed gasification system to produce a synthesis gas containing olefins, hydrogen and carbon monoxide followed by a catalytic liquefaction step to convert the synthesis gas to liquid hydrocarbon fuel. The major emphasis on the project at the present time is to maximize product yield. A level of 60 gals of diesel type fuel per ton of feedstock (dry, ash free basis) is expected. Numerous materials have been processed through the conversion system without any significant change in product quality (essentially C/sub 7/-C/sub 17/ paraffinic hydrocarbons with cetane indicies of 50+). Other tasks in progress include factor studies, process simplification, process control and scale-up to a 10 ton/day Engineering Test Facility. 18 references, 4 figures, 9 tables.

  2. Evidence of delayed light emission of TetraPhenyl Butadiene excited by liquid Argon scintillation light

    E-Print Network [OSTI]

    Ettore Segreto

    2015-03-29

    TetraPhenyl Butadiene is the wavelength shifter most widely used in combination with liquid Argon. The latter emits scintillation photons with a wavelength of 127 nm that need to be downshifted to be detected by photomultipliers with glass or quartz windows. TetraPhenyl Butadiene has been demonstrated to have an extremely high conversion efficiency, possibly higher than 100 % for 127 nm photons, while there is no precise information about the time dependence of its emission. It is usually assumed to be exponentially decaying with a characteristic time of the order of one ns, as an extrapolation from measurements with exciting radiation in the near UV. This work shows that TetraPhenyl Butadiene, when excited by 127 nm photons, reemits photons not only with a very short decay time, but also with slower ones due to triplet states de-excitations. This fact can strongly contribute to clarify the anomalies in liquid Argon scintillation light reported in literature since seventies, namely the inconsistency in the measured values of the long decay time constant and the appearance of an intermediate component. Similar effects should be also expected when the TPB is used in combination with Helium and Neon, that emit scintillation photons with wavelengths shorter than 127 nm.

  20. Measurements and calculations of oscillations and phase relations in the driven gas-phase combustion of acetaldehyde

    SciTech Connect (OSTI)

    Tsujimoto, K.K.; Hjelmfelt, A.; Ross, J. (Department of Chemistry, Stanford University, Stanford, California (USA))

    1991-09-01

    Oscillations in light emission and species concentrations, are measured as periodic perturbations are simultaneously applied to the input rates of acetaldehyde and oxygen in the gas-phase combustion of acetaldehyde in a continuous-flow stirred tank reactor for conditions where the autonomous reaction itself is oscillatory. The experimental results are compared with the predictions of a five-variable thermokinetic model. We measure periodic responses in the fundamental entrainment band (ratio of frequency of perturbation to frequency of response equal to unity) for four different values of phase shift between the acetaldehyde and oxygen perturbation wave forms as we vary the frequency and amplitude of the external periodic perturbations. Outside of the entrainment bands we find quasiperiodic response. We determine the phases of the light emission and six species concentrations, as measured with a mass spectrometer, with respect to the periodic perturbation, the variation of these phases across the fundamental entrainment band for different values of reactant phase shift and for different amplitudes of perturbation, and the effects of the phase shift between the two input perturbations on the light emission response of the system for different frequencies of perturbation. Both the experiments and calculations predict a widening of the entrainment band with an increase in perturbation amplitude, and the same variation in bandwidths for the four values of reactant phase shift studied. The experiments and calculations also predict the same general trends in light phase and species phases (difference between the light emission and species concentrations with respect to the perturbing wave form) as the band is traversed for different amplitudes of perturbation and for different values of reactant phase shift.

    2011-01-01

    The reactive uptake of carbonyl-containing volatile organic compounds (cVOCs) by aqueous atmospheric aerosols is a likely source of particulate organic material. The aqueous-phase secondary organic products of some cVOCs are surface-active. Therefore, cVOC uptake can lead to organic film formation at the gas-aerosol interface and changes in aerosol surface tension. We examined the chemical reactions of two abundant cVOCs, formaldehyde and acetaldehyde, in water and aqueous ammonium sulfate (AS) solutions mimicking tropospheric aerosols. Secondary organic products were identified using Aerosol Chemical Ionization Mass Spectrometry (Aerosol-CIMS), and changes in surface tension were monitored using pendant drop tensiometry. Hemiacetal oligomers and aldol condensation products were identified using Aerosol-CIMS. A hemiacetal sulfate ester was tentatively identified in the formaldehyde-AS system. Acetaldehyde depresses surface tension to 65(\\pm2) dyn/cm in pure water and 62(\\pm1) dyn/cm in AS solutions. Surface t...

    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.

  18. Clean Diesel Component Improvement Program

    SciTech Connect (OSTI)

    2005-06-30

    The research conducted in this program significantly increased the knowledge and understanding in the fields of plasma physics and chemistry in diesel exhaust, the performance and characteristics of multifunctional catalysts in diesel exhaust, and the complexities of controlling a combination of such systems to remove NOx. Initially this program was designed to use an in-line plasma system (know as a plasma assisted catalyst system or PAC) to convert NO {yields} NO{sub 2}, a more catalytically active form of nitrogen oxides, and to crack hydrocarbons (diesel fuel in particular) into active species. The NO{sub 2} and the cracked hydrocarbons were then flowed over an in-line ceramic NOx catalyst that removed NO{sub 2} from the diesel exhaust. Even though the PAC system performed well technically and was able to remove over 95% of NOx from diesel exhaust the plasma component proved not to be practical or commercially feasible. The lack of practical and commercial viability was due to high unit costs and lack of robustness. The plasma system and its function was replaced in the NOx removal process by a cracking reforming catalyst that converted diesel fuel to a highly active reductant for NOx over a downstream ceramic NOx catalyst. This system was designated the ceramic catalyst system (CCS). It was also determined that NO conversion to NO{sub 2} was not required to achieve high levels of NOx reduction over ceramic NOx catalyst if that catalyst was properly formulated and the cracking reforming produced a reductant optimized for that NOx catalyst formulation. This system has demonstrated 92% NOx reduction in a diesel exhaust slipstream and 65% NOx reduction from the full exhaust of a 165 hp diesel engine using the FTP cycle. Although this system needs additional development to be commercial, it is simple, cost effective (does not use precious metals), sulfur tolerant, operates at high space velocities, does not require a second fluid be supplied as a reductant, has low parasitic loss of 2-3% and achieves high levels of NOx reduction. This project benefits the public by providing a simple low-cost technology to remove NOx pollutants from the exhaust of almost any combustion source. The reduction of NOx emissions emitted into the troposphere provides well documented improvement in health for the majority of United States citizens. The emissions reduction produced by this technology helps remove the environmental constraints to economic growth.

    2006-11-01

    Present federal tax incentives apply to certain types of biomass-derived diesel fuels, which in energy policy and tax laws are described either as renewable diesel or biodiesel. To understand the distinctions between these diesel types it is necessary to understand the technologies used to produce them and the properties of the resulting products. This fact sheet contains definitions of renewable and biodiesel and discusses the processes used to convert biomass to diesel fuel and the properties of biodiesel and renewable diesel fuels.

  8. Physical properties of bio-diesel & Implications for use of bio-diesel in diesel engines

    In this study we identify components of a typical biodiesel fuel and estimate both their individual and mixed thermo-physical and transport properties. We then use the estimated mixture properties in computational simulations to gauge the extent to which combustion is modified when biodiesel is substituted for conventional diesel fuel. Our simulation studies included both regular diesel combustion (DI) and premixed charge compression ignition (PCCI). Preliminary results indicate that biodiesel ignition is significantly delayed due to slower liquid evaporation, with the effects being more pronounced for DI than PCCI. The lower vapor pressure and higher liquid heat capacity of biodiesel are two key contributors to this slower rate of evaporation. Other physical properties are more similar between the two fuels, and their impacts are not clearly evident in the present study. Future studies of diesel combustion sensitivity to both physical and chemical properties of biodiesel are suggested.

  10. The effect of diesel injection timing on a turbocharged diesel engine fumigated with ethanol

    1988-01-01

    A study has been done to determine the effect of changes in diesel injection timing on engine performance using a multicylinder, turbocharged diesel engine fumigated with ethanol. Tests at half load with engine speeds of 2000 and 2400 rpm indicated that a 4% increase in thermal efficiency could be obtained by advancing the diesel injection timing from 18 to 29/sup 0/BTDC. The effect of changes in diesel timing was much more pronounced at 2400 rpm. Advancing the diesel timing decreased CO and unburned HC levels significantly. The increase in NO levels due to advances in diesel timing was offset by the decrease in NO due to ethanol addition.

    A large number of current and future experiments in neutrino and dark matter detection use the scintillation light from noble elements as a mechanism for measuring energy deposition. The scintillation light from these elements is produced in the extreme ultraviolet (EUV) range, from 60 - 200 nm. Currently, the most practical technique for observing light at these wavelengths is to surround the scintillation volume with a thin film of Tetraphenyl Butadiene (TPB) to act as a fluor. The TPB film absorbs EUV photons and reemits visible photons, detectable with a variety of commercial photosensors. Here we present a measurement of the re-emission spectrum of TPB films when illuminated with 128, 160, 175, and 250 nm light. We also measure the fluorescence efficiency as a function of incident wavelength from 120 to 250 nm.

    2013-01-01

    Time-resolved coincidence imaging of photoelectrons and photoions represents the most complete experimental measurement of ultrafast excited state dynamics, a multi-dimensional measurement for a multi-dimensional problem. Here we present the experimental data from recent coincidence imaging experiments, undertaken with the aim of gaining insight into the complex ultrafast excited-state dynamics of 1,3-butadiene initiated by absorption of 200 nm light. We discuss photoion and photoelectron mappings of increasing dimensionality, and focus particularly on the time-resolved photoelectron angular distributions (TRPADs), expected to be a sensitive probe of the electronic evolution of the excited state and to provide significant information beyond the time-resolved photoelectron spectrum (TRPES). Complex temporal behaviour is observed in the TRPADs, revealing their sensitivity to the dynamics while also emphasising the difficulty of interpretation of these complex observables. From the experimental data some details...

    Baker, Quentin A. (San Antonio, TX)

    1985-01-01

    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.

  15. Selective hydrogenation of 1,3-butadiene on platinum–copper alloys at the single-atom limit

    SciTech Connect (OSTI)

    Lucci, Felicia R.; Liu, Jilei; Marcinkowski, Matthew D.; Yang, Ming; Allard, Lawrence F.; Flytzani-Stephanopoulos, Maria; Sykes, E. Charles H.

    Platinum is ubiquitous in the production sectors of chemicals and fuels; however, its scarcity in nature and high price will limit future proliferation of platinum-catalysed reactions. One definite approach to conserve platinum involves understanding the smallest number of platinum atoms needed to catalyse a reaction, then designing catalysts with the minimal platinum ensembles. Here we design and test a new generation of platinum–copper nanoparticle catalysts for the selective hydrogenation of 1,3-butadiene,, an industrially important reaction. Isolated platinum atom geometries enable hydrogen activation and spillover but are incapable of C–C bond scission that leads to loss of selectivity and catalyst deactivation. ?-Alumina-supported single-atom alloy nanoparticle catalysts with <1 platinum atom per 100 copper atoms are found to exhibit high activity and selectivity for butadiene hydrogenation to butenes under mild conditions, demonstrating transferability from the model study to the catalytic reaction under practical conditions.

    2006-01-01

    The structure of a laminar rich premixed 1,3-C4H6/CH4/O2/Ar flame have been investigated. 1,3-Butadiene, methane, oxygen and argon mole fractions are 0.033; 0.2073; 0.3315, and 0.4280, respectively, for an equivalent ratio of 1.80. The flame has been stabilized on a burner at a pressure of 6.7 kPa (50 Torr). The concentration profiles of stable species were measured by gas chromatography after sampling with a quartz probe. Quantified species included carbon monoxide and dioxide, methane, oxygen, hydrogen, ethane, ethylene, acetylene, propyne, allene, propene, cyclopropane, 1,3-butadiene, butenes, 1-butyne, vinylacetylene, diacetylene, C5 compounds, benzene, and toluene. The temperature was measured thanks to a thermocouple in PtRh (6%)-PtRh (30%) settled inside the enclosure and ranged from 900 K close to the burner up to 2100 K.

    An improved method is provided for separating acrylonitrile butadiene styrene (ABS) and high impact polystyrene (HIPS) plastics from each other. The ABS and HIPS plastics are shredded to provide a selected particle size. The shredded particles of the ABS and HIPS plastics are applied to a solution having a solution density in a predefined range between 1.055 gm/cm.sup.3 and 1.07 gm/cm.sup.3, a predefined surface tension in a range between 22 dynes/cm to 40 dynes/cm and a pH in the range of 1.77 and 2.05. In accordance with a feature of the invention, the novel method is provided for separating ABS and HIPS, two solid thermoplastics which have similar densities by selectively modifying the effective density of the HIPS using a binary solution with the appropriate properties, such as pH, density and surface tension, such as a solution of acetic acid and water or a quaternary solution having the appropriate density, surface tension, and pH.

  12. Diesel lube oils; Fourth dimension of diesel particulate control

    SciTech Connect (OSTI)

    Springer, K.J. (Southwest Research Institute, San Antonio, TX (US))

    1989-07-01

    Particulate emission control, for the HD diesel engine, has previously been considered a three-dimensional problem involving: combustion of the fuel by the engine, fuel modification, and exhaust aftertreatment. The lube oil contribution may be considered a fourth dimension of the problem. Historically, the heavy-duty engine manufacturer has met emission standards for smoke (1968 to present), CO, HC, and NOx (1974 to present) and particulates (1988 to present) through changes in engine design. This paper used the allocation method to estimate the reduction in lube oil consumption needed to meet 1991 and 1994 U.S. particulate emission standards. This analysis places the contribution of lube oil as a source of exhaust particulates into prospective with the contributions from fuel sulfur and fuel combustion. An emissions control strategy to meet future regulations is offered in which reductions from fuel modification, combustion improvement, reduced lube oil consumption, and exhaust particulate trap-catalysts are all involved.

  13. Dual-fueling diesel/NGV technology

    SciTech Connect (OSTI)

    Heenan, J.; Gettel, L

    1988-01-01

    The use of natural gas as a transportation fuel reduces operating costs and emissions and contributes to security of supply. Natural gas for vehicles (NGV) can be used in rail, road, marine and off-road applications as a replacement for diesel fuel either stored as liquefied natural gas (LNG) or compressed natural gas (CNG). These applications have large energy consumptions per engine which makes them attractive target markets. When NGV replaces diesel as a fuel, either engines are converted to spark ignition (Otto Cycle) or a small amount of diesel fuel is used as for pilot ignition (Dual fuel).

The power plants were audited, including INDE's largest isolated diesel station, and two, much smaller municipal and privately owned stations. I returned to Oak Ridge on February 22, 1990.

  4. Recent Developments in BMW's Diesel Technology

    SciTech Connect (OSTI)

    Steinparzer, F

    2003-08-24

    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.

    Diesel engines are the dominant propulsion engine of choice for most of the commercial surface transportation applications in the world. Consider agricultural uses: Diesel engine power is used to prepare the soil, transport the bulk seed or seedlings, pump irrigation water, and spray fertilizers, mechanically harvest some crops and distribute the produce to market. Diesel engines power virtually all of the off-highway construction equipment. Deep water commercial freighters or containerships are almost all diesel engine powered. The passenger ships are primarily either diesel or a combination of diesel and gas turbine, referred to as CODAG or CODOG.

  7. Alternatives to conventional diesel fuel-some potential implications of California's TAC decision on diesel particulate.

    Eberhardt, J. J.; Rote, D. M.; Saricks, C. L.; Stodolsky, F.

    1999-08-10

    Limitations on the use of petroleum-based diesel fuel in California could occur pursuant to the 1998 declaration by California's Air Resources Board (CARB) that the particulate matter component of diesel exhaust is a carcinogen, therefore a toxic air contaminant (TAC) subject to provisions of the state's Proposition 65. It is the declared intention of CARB not to ban or restrict diesel fuel, per se, at this time. Assuming no total ban, Argonne National Laboratory (ANL) explored two feasible ''mid-course'' strategies. (1) Increased penetration of natural gas and greater gasoline use in the transportation fuels market, to the extent that some compression-ignition (CI) applications revert to spark-ignition (SI) engines. (2) New specifications requiring diesel fuel reformulation based on exhaust products of individual diesel fuel constituents. Each of these alternatives results in some degree of (conventional) diesel displacement. In the first case, diesel fuel is assumed admissible for ignition assistance as a pilot fuel in natural gas (NG)-powered heavy-duty vehicles, and gasoline demand in California increases by 32.2 million liters per day overall, about 21 percent above projected 2010 baseline demand. Natural gas demand increases by 13.6 million diesel liter equivalents per day, about 7 percent above projected (total) consumption level. In the second case, compression-ignition engines utilize substitutes for petroleum-based diesel having similar ignition and performance properties. For each case we estimated localized air emission plus generalized greenhouse gas and energy changes. Economic implications of vehicle and engine replacement were not evaluated.

    Three alternative diesel fuels were screened by analysis of fuel injector tip deposits. The test engines were operated on the Peterson (torque) test cycle; the average carbon deposit volume on an injector tip was measured by a computer vision method. Relative coke deposit quantity was obtained by area analysis of injector tip images. Repetitive image areas varied less than 1%. Coke deposit areas for repetitive fuel tests also varied less than 1%. Injector coking tendencies of tested fuels decreased in the following order: peanut oil, no. 2 diesel, tricaprylin, and tributyrin/no. 2 diesel blend. The observed dependence of the relative coke quantity on fuel type was consistent with the results from a photographic technique used previously for fuel screening. 10 refs., 2 figs., 2 tabs.

    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.

    New 6 cylinder direct injection 11 liter diesel engines which have naturally aspirated, turbocharged, and turbocharged-aftercooled versions have been developed and moved in production at the end of 1983. The highest output of the turbocharged-aftercooled version is 276 kW (375 ps) at 2200 RPM. Based on Komatsu new technologies 125 mm bore diesel has been designed to meet the users' demands, such as compact in size, light in weight, extremely high performance, high reliability and durability. The turbocharged and turbocharged-aftercooled engines are characterized by the adoption of the ductile cast iron piston which is the first application into the high speed, four cycle diesels in production in the world, and which was enabled by Komatsu design and precision casting technologies. This paper also covers the other design aspects and performance characteristics.

    Fleisch, T.H.; Meurer, P.C.

    1996-07-01

    Engine tests demonstrate that dimethyl ether (DME, CH{sub 3}OCH{sub 3}) can provide an alternative approach toward efficient, ultra-clean and quiet compression ignition (CI) engines. From a combustion point of view, DME is an attractive alternative fuel for CI engines, primarily for commercial applications in urban areas, where ultra-low emissions will be required in the future. DME can resolve the classical diesel emission problem of smoke emissions, which are completely eliminated. With a properly developed DME injection and combustion system, NO{sub x} emissions can be reduced to 40% of Euro II or U.S. 1998 limits, and can meet the future ULEV standards of California. Simultaneously, the combustion noise is reduced by as much as 15 dB(A) below diesel levels. In addition, the classical diesel advantages such as high thermal efficiency, compression ignition, engine robustness, etc., are retained.

    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.

    Platinum is ubiquitous in the production sectors of chemicals and fuels; however, its scarcity in nature and high price will limit future proliferation of platinum-catalysed reactions. One definite approach to conserve platinum involves understanding the smallest number of platinum atoms needed to catalyse a reaction, then designing catalysts with the minimal platinum ensembles. Here we design and test a new generation of platinum–copper nanoparticle catalysts for the selective hydrogenation of 1,3-butadiene,, an industrially important reaction. Isolated platinum atom geometries enable hydrogen activation and spillover but are incapable of C–C bond scission that leads to loss of selectivity and catalyst deactivation.more »?-Alumina-supported single-atom alloy nanoparticle catalysts with « less

    Candido, S.S.; Crisostomo, E.V.

    1997-01-27

    In anticipation of tightening sulfur specifications on diesel fuel, Petron Corp. built a new 18,000 b/sd gas oil desulfurization unit (GODU) at its refinery in Bataan, Philippines. The GODU gives Petron sufficient diesel oil desulfurization capacity to meet demand for lower-sulfur diesel in the country. The project places the refinery in a pacesetter position to comply with the Philippine government`s moves to reduce air pollution, especially in urban centers, by reducing the sulfur specification for diesel to 0.5 wt% in 1996 from 0.7 wt% at the start of the project. Performance tests and initial operations of the unit have revealed a desulfurization efficiency of 91% vs. a guaranteed efficiency of 90%. A feed sulfur content of 1.33 wt% is reduced to 0.12 wt% at normal operating conditions. Operating difficulties during start-up were minimized through use of a detailed prestartup check conducted during the early stages of construction work.

    1999-04-26

    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.

    1999-04-26

    The DOE Office of Heavy Vehicle Technologies (OHVT) and its predecessor organizations have maintained aggressive projects in diesel exhaust aftertreatment since 1993. The Energy Policy Act of 1992, Section 2027, specifically authorized DOE to help accelerate the ability of U. S. diesel engine manufacturers to meet emissions regulations while maintaining the compression ignition engines inherently high efficiency. A variety of concepts and devices have been evaluated for NOx and Particulate matter (PM) control. Additionally, supporting technology in diagnostics for catalysis, PM measurement, and catalyst/reductant systems are being developed. This paper provides a summary of technologies that have been investigated and provides recent results from ongoing DOE-sponsored R and D. NOx control has been explored via active NOx catalysis, several plasma-assisted systems, electrochemical cells, and fuel additives. Both catalytic and non-catalytic filter technologies have been investigated for PM control.

    The University of Minnesota Center for Diesel Research along with a research team including Caterpillar, Cummins, Carnegie Mellon University, West Virginia University (WVU), Paul Scherrer Institute in Switzerland, and Tampere University in Finland have performed measurements of Diesel exhaust particle size distributions under real-world dilution conditions. A mobile aerosol emission laboratory (MEL) equipped to measure particle size distributions, number concentrations, surface area concentrations, particle bound PAHs, as well as CO 2 and NO x concentrations in real time was built and will be described. The MEL was used to follow two different Cummins powered tractors, one with an older engine (L10) and one with a state-of-the-art engine (ISM), on rural highways and measure particles in their exhaust plumes. This paper will describe the goals and objectives of the study and will describe representative particle size distributions observed in roadway experiments with the truck powered by the ISM engine.

    M and W Gear Co. of Gibson City, IL, are marketing a new alcohol- injection system that permits turbocharged diesel engines to burn alcohol and claims to cut diesel consumption by 30% and more. The alcohol fuel, a blend of alcohol and water, does not meet the diesel fuel until the alcohol has been atomized and sprayed through the intake manifold into the cylinders. It permits farmers to use home- still-produced ethanol without the added expense of refining to anhydrous composition.

    An exhaust system that processes exhaust generated by an engine includes a diesel particulate filter (DPF) that is disposed downstream of the engine and that filters particulates from the exhaust. An electrical heater is disposed upstream of the DPF and selectively heats the exhaust to initiate combustion of the particulates within the exhaust as it passes therethrough. Heat generated by combustion of the particulates induces combustion of particulates within the DPF.

    SciTech Connect (OSTI)

    Baring-Gould, I.; Corbus, D.

    2007-12-01

    The rising cost of diesel fuel and the environmental regulation for its transportation, use, and storage, combined with the clear impacts of increased arctic temperatures, is driving remote communities to examine alternative methods of providing power. Over the past few years, wind energy has been increasingly used to reduce diesel fuel consumption, providing economic, environmental, and security benefits to the energy supply of communities from Alaska to Antarctica. This summary paper describes the current state of wind-diesel systems, reviews the operation of wind-diesel plants in cold climates, discusses current research activities pertaining to these systems, and addresses their technical and commercial challenges. System architectures, dispatch strategies, and operating experience from a variety of wind-diesel systems in Alaska will be reviewed. Specific focus will also be given to the control of power systems with large amounts of wind generation and the complexities of replacing diesel engine waste heat with excess wind energy, a key factor in assessing power plants for retrofit. A brief overview of steps for assessing the viability of retrofitting diesel power systems with wind technologies will also be provided. Because of the large number of isolated diesel minigrids, the market for adding wind to these systems is substantial, specifically in arctic climates and on islands that rely on diesel-only power generation.

  3. Progress in diesel engine emissions control

    SciTech Connect (OSTI)

    Khair, M.K. (Southwest Research Inst., San Antonio, TX (United States))

    1992-07-01

    A considerable amount of work was carried out in the mid-1980s to develop heavy-duty diesel engines that could meet limits on particulate emissions. These limits, although high by today's standards, were considered very restrictive. Some manufacturers struggled to achieve the 0.6 g/bhp-h particulate matter limit with enough margin for production variabilities and to account for the deterioration factor. Significant progress was achieved in diesel emissions control through engine and fuel system design changes. This eventually made it possible to meet a particulate level of 0.25 g/bhp-h for 1991. The next target level for particulate emissions is 0.1 g/bhp-h for the 1994 heavy-duty engine. To meet the challenge, engine developers are not only considering engine and injection system design changes but also fuel improvements and exhaust aftertreatment. This paper includes a review of past and current strategies used to control emissions in the modern diesel engine.

    The objectives of this research program are to develop information on lubricity and viscosity improvers and their impact on the wear mechanisms in fuel injectors operating on blends of dimethyl ether (DME) and diesel fuel. This project complements another ongoing project titled ''Development of a Dimethyl Ether (DME)-Fueled Shuttle Bus Demonstration Project''. The objectives of that research and demonstration program are to convert a campus shuttle bus to operation on dimethyl ether, a potential ultra-clean alternative diesel fuel. To accomplish this objective, this project includes laboratory evaluation of a fuel conversion strategy, as well as, field demonstration of the DME-fueled shuttle bus. Since DME is a fuel with no lubricity (i.e., it does not possess the lubricating quality of diesel fuel), conventional fuel delivery and fuel injection systems are not compatible with dimethyl ether. Therefore, to operate a diesel engine on DME one must develop a fuel-tolerant injection system, or find a way to provide the necessary lubricity to the DME. In the shuttle bus project, they have chosen the latter strategy in order to achieve the objective with minimal need to modify the engine. The strategy is to blend DME with diesel fuel, to obtain the necessary lubricity to protect the fuel injection system and to achieve low emissions. In this project, they have sought to develop methods for extending the permissible DME content in the DME-diesel blends without experiencing rapid injector failure due to wear. To date, the activities have covered two areas: development of a high-pressure lubricity test apparatus for studies of lubricity and viscosity improvers and development of an injector durability stand for evaluation of wear rates in fuel injectors. This report provides summaries of the progress toward completion of both experimental systems and a summary of the plan for completion of the project objectives.

  18. Vibrational quasi-degenerate perturbation theory with optimized coordinates: Applications to ethylene and trans-1,3-butadiene

    A perturbative extension to optimized coordinate vibrational self-consistent field (oc-VSCF) is proposed based on the quasi-degenerate perturbation theory (QDPT). A scheme to construct the degenerate space (P space) is developed, which incorporates degenerate configurations and alleviates the divergence of perturbative expansion due to localized coordinates in oc-VSCF (e.g., local O–H stretching modes of water). An efficient configuration selection scheme is also implemented, which screens out the Hamiltonian matrix element between the P space configuration (p) and the complementary Q space configuration (q) based on a difference in their quantum numbers (?{sub pq} = ?{sub s}|p{sub s} ? q{sub s}|). It is demonstrated that the second-order vibrational QDPT based on optimized coordinates (oc-VQDPT2) smoothly converges with respect to the order of the mode coupling, and outperforms the conventional one based on normal coordinates. Furthermore, an improved, fast algorithm is developed for optimizing the coordinates. First, the minimization of the VSCF energy is conducted in a restricted parameter space, in which only a portion of pairs of coordinates is selectively transformed. A rational index is devised for this purpose, which identifies the important coordinate pairs to mix from others that may remain unchanged based on the magnitude of harmonic coupling induced by the transformation. Second, a cubic force field (CFF) is employed in place of a quartic force field, which bypasses intensive procedures that arise due to the presence of the fourth-order force constants. It is found that oc-VSCF based on CFF together with the pair selection scheme yields the coordinates similar in character to the conventional ones such that the final vibrational energy is affected very little while gaining an order of magnitude acceleration. The proposed method is applied to ethylene and trans-1,3-butadiene. An accurate, multi-resolution potential, which combines the MP2 and coupled-cluster with singles, doubles, and perturbative triples level of electronic structure theory, is generated and employed in the oc-VQDPT2 calculation to obtain the fundamental tones as well as selected overtones/combination tones coupled to the fundamentals through the Fermi resonance. The calculated frequencies of ethylene and trans-1,3-butadiene are found to be in excellent agreement with the experimental values with a mean absolute error of 8 and 9 cm{sup ?1}, respectively.

Our strategy is to blend DME with diesel fuel, to obtain the necessary lubricity to protect the fuel injection system and to achieve low emissions. In this project, we have sought to develop methods for extending the permissible DME content in the DME-diesel blends without experiencing rapid injector failure due to wear. Our activities have covered three areas: examination of the impact of lubricity additives on the viscosity of DME, development of a high-pressure lubricity test apparatus for studies of lubricity and viscosity improvers and development of an injector durability stand for evaluation of wear rates in fuel injectors. The first two of these areas have resulted in valuable information about the limitations of lubricity and viscosity additives that are presently available in terms of their impact on the viscosity of DME and on wear rates on injector hardware. The third area, that of development of an injector durability test stand, has not resulted in a functioning experiment. Some information is provided in this report to identify the remaining tasks that need to be performed to make the injector stand operational. The key observations from the work are that when blended at 25 wt.% in either diesel fuel or Biodiesel fuel, DME requires more than 5 wt.% additive of all viscosity and lubricity additives tested here to even approach the lower limit of the ASTM diesel fuel viscosity requirement. To treat neat DME sufficiently to make DME comply with the ASTM diesel fuel viscosity requirement would require a viscosity additive with 10{sup 45} cSt viscosity, which is not possible with current additive technologies.

    The detection of VUV scintillation light, e.g. in (liquid) argon detectors, commonly includes a reflector with a fluorescent coating, converting UV photons to visible light. The light yield of these detectors depends directly on the conversion efficiency. Several coating/reflector combinations were produced using VM2000, a specular reflecting multi layer polymer, and Tetratex, a diffuse reflecting PTFE fabric, as reflector foils. The efficiency of these coatings was optimised and has been measured in a dedicated liquid argon setup built at the University of Zurich. It employs a small, 1.3 kg LAr cell viewed by a 3-inch, low radioactivity PMT of type R11065-10 from Hamamatsu. The cryogenic stability of these coatings was additionally studied. The optimum reflector/coating combination was found to be Tetratex dip coated with Tetraphenyl-butadiene with a thickness of 0.9 mg/cm$^2$ resulting in a 3.6 times higher light yield compared to uncoated VM2000. Its performance was stable in long term measurements, ran up...

    P-terphenyl (PT) and tetraphenyl-butadiene (TPB) in form of thin films have been investigated as possible wavelength shifting material for application in Ring Imaging Cherenkov (RICH) detectors. Films of dierent thickness were evaporated onto borosilicate windows of photomultiplier tubes (PMT) and the quantum eciency of the modified PMTs was determined as a function of wavelength. Gain factors for the number of measured photoelectrons in dependence on the cuto wavelength (energy) for application in Cherenkov counters were established. Using PT, a strong increase in quantum eciency between 200 nm and 300 nm was observed leading to gain factors as high as 1.71 ± 0.11 for a cutoff energy of 6.2 eV. Due to strong absorption in the wavelength range between 300 nm and 400 nm, TPB shows inferior results. No significant thickness dependence was observed for films thicker than 600 nm. Film morphology and wavelength dependent fluorescence was measured to back the results. Simulations encourage the use on flat panel mu...

    A heat release correlation for oxygen-enriched diesel combustion is being developed through heat release analysis of cylinder pressure data from a single-cylinder diesel engine operating under various levels of oxygen enrichment. Results show that standard combustion correlations available in the literature do not accurately describe oxygen-enriched diesel combustion. A novel functional form is therefore proposed, which is shown to reproduce measured heat release profiles closely, under different operating conditions and levels of oxygen enrichment. The mathematical complexity of the associated curve-fitting problem is maintained at the same level of difficulty as for standard correlations. When the novel correlation is incorporated into a computer simulation of diesel engine operation with oxygen enrichment, the latter predicts pressure traces in excellent agreement with measured pressure data. This demonstrates the potential of the proposed combustion simulation to guide the application of oxygen-enriched technology successfully to a variety of multicylinder diesel systems.

    The single stage rotary Wankel engine is difficult to convert into a diesel version having an adequate compression ratio and a compatible combustion chamber configuration. Past efforts in designing a rotary-type Wankel diesel engine resorted to a two-stage design. Complexity, size, weight, cost and performance penalties were some of the drawbacks of the two-stage Wankel-type diesel designs. This paper presents an approach to a single stage low compression ratio Wankel-type rotary engine. Cold starting of a low compression ratio single stage diesel Wankel becomes the key problem. It was demonstrated that the low compression single stage diesel Wankel type rotary engine can satisfactorily be cold started with a properly designed combustion chamber in the rotor and a variable heat input combustion aid.

    Advanced combustion regimes such as homogeneous charge compression ignition (HCCI) and premixed charge compression ignition (PCCI) offer benefits of reduced nitrogen oxides (NOx) and particulate matter (PM) emissions. However, these combustion strategies often generate higher carbon monoxide (CO) and hydrocarbon (HC) emissions. In addition, aldehydes and ketone emissions can increase in these modes. In this study, the engine-out emissions of a compression-ignition engine operating in a fuel reactivity- controlled PCCI combustion mode using in-cylinder blending of gasoline and diesel fuel have been characterized. The work was performed on a 1.9-liter, 4-cylinder diesel engine outfitted with a port fuel injection system to deliver gasoline to the engine. The engine was operated at 2300 rpm and 4.2 bar brake mean effective pressure (BMEP) with the ratio of gasoline to diesel fuel that gave the highest engine efficiency and lowest emissions. Engine-out emissions for aldehydes, ketones and PM were compared with emissions from conventional diesel combustion. Sampling and analysis was carried out following micro-tunnel dilution of the exhaust. Particle geometric mean diameter, number-size distribution, and total number concentration were measured by a scanning mobility particle sizer (SMPS). For the particle mass measurements, samples were collected on Teflon-coated quartz-fiber filters and analyzed gravimetrically. Gaseous aldehydes and ketones were sampled using dinitrophenylhydrazine-coated solid phase extraction cartridges and the extracts were analyzed by liquid chromatography/mass spectrometry (LC/MS). In addition, emissions after a diesel oxidation catalyst (DOC) were also measured to investigate the destruction of CO, HC and formaldehydes by the catalyst.

    The presence of nitro-polycyclic aromatic hydrocarbons (NPAHs) in diesel fuel emissions has been studied for a number of years predominantly because of their contribution to the overall health and environmental risks associated with these emissions. Electron monochromator-mass spectrometry (EM-MS) is a highly selective and sensitive method for detection of NPAHs in complex matrixes, such as diesel emissions. Here, EM-MS was used to compare the levels of NPAHs in fuel emissions from conventional (petroleum) diesel, ultra-low sulfur/low-aromatic content diesel, Fischer-Tropsch synthetic diesel, and conventional diesel/synthetic diesel blend. The largest quantities of NPAHs were detected in the conventional diesel fuel emissions, while the ultra-low sulfur diesel and synthetic diesel fuel demonstrated a more than 50% reduction of NPAH quantities when compared to the conventional diesel fuel emissions. The emissions from the blend of conventional diesel with 30% synthetic diesel fuel also demonstrated a more than 30% reduction of the NPAH content when compared to the conventional diesel fuel emissions. In addition, a correlation was made between the aromatic content of the different fuel types and NPAH quantities and between the nitrogen oxides emissions from the different fuel types and NPAH quantities. The EM-MS system demonstrated high selectivity and sensitivity for detection of the NPAHs in the emissions with minimal sample cleanup required.

  9. Understanding diesel engine lubrication at low temperature

    This paper reports on oil pumpability in passenger car gasoline engines that was well-characterized by an ASTM program and by individual researchers in the 1970's and early 1980's. oil pumpability in diesel engines however, was not investigated to any significant extent until the mid-1980's. This study was initiated to define the performance of several commercial viscosity modifiers in different formulations containing 3 detergent-inhibitor (DI) additive packages and 4 basestock types. The test oils were run at {minus}18{degrees} C (0{degrees} F) in a Cummins NTC-400 diesel engine. The results, when statistically analyzed, indicated that a new, second generation olefin copolymer (OCP) viscosity modifier has better performance that a first generation OCP and, furthermore, had performance equal to a polymethacrylate (PMA) viscosity modifier. The analysis also showed that one DI/base stock combination had a significant effect on performance. The apparent shear rate of the oil in the pump inlet tube was calculated from the oil pump flow rate measured at idle speed at low temperature and the pump inlet tube diameter. The shear rate and oil viscosity were used to estimate the shear stress in the pump inlet tube. The shear stress level of the engine is 56% higher than the Mini-Rotary Viscometer (MRV). Hence, the current MRV procedure is rheologically unsuitable to predict pumpability in a large diesel engine. A new device was developed for measuring the oil film thickness in the turbocharge bearing and noting the time when a full oil film is formed. Results indicate that a full oil film occurs almost immediately, well before any oil pressure is observed at the turbocharge inlet. Residual oil remaining in the bearing after shutdown may account of this observation. The oil film maintained its thickness both before, and after the first indication of oil pressure. More work is needed to study this effect.

  10. Straight Vegetable Oil as a Diesel Fuel?

    2014-01-01

    Biodiesel, a renewable fuel produced from animal fats or vegetable oils, is popular among many vehicle owners and fleet managers seeking to reduce emissions and support U.S. energy security. Questions sometimes arise about the viability of fueling vehicles with straight vegetable oil (SVO), or waste oils from cooking and other processes, without intermediate processing. But SVO and waste oils differ from biodiesel (and conventional diesel) in some important ways and are generally not considered acceptable vehicle fuels for large-scale or long-term use.
