DPF's Regeneration Procedures and Emissions with RME Blend Fuels

2012-06-18
The fatty acid methyl esters (FAME's) - in Europe mostly RME (Rapeseed methyl ester) - are used in several countries as alternative biogene Diesel fuels in various blending ratios with fossil fuels (Bxx). Questions often arise about the influences of these biocomponents on the modern exhaust aftertreatment systems and especially on the regeneration of Diesel particle filters (DPF). In the present work different regeneration procedures of DPF systems were investigated with biofuels B0, B20 & B100. The tested regeneration procedures were: passive regenerations: DOC + CSF; CSF alone, active regenerations: standstill burner; fuel injections & DOC. During each regeneration on-line measurements of regulated and unregulated emission components (nanoparticles & FTIR) were conducted. It can be stated that the increased portion of RME in fuel provokes longer time periods to charge the filter with soot.

Development, Verification, and Validation of Penn State Extended Range Electric Vehicle

2012-06-05
The Pennsylvania State University is one of 16 North American universities that participated in the EcoCAR advanced vehicle technology competition (http://www.ecocarchallenge.org/). A series-hybrid-electric vehicle based on a General Motors crossover SUV platform has been designed, built and tested for this purpose. The powertrain features a 1.3 L turbodiesel engine running on a B20 fuel system, a 75kW generator directly coupled to the engine and advanced lithium-ion batteries. In this paper, the vehicle architecture and control strategy are detailed and performance predictions (e.g., acceleration, fuel consumption and emissions) are presented. This includes discussion of the development process that led to the selected designs. The predicted performance is compared with data obtained on a chassis dynamometer and during on-road measurements over specified drive cycles. Presenter Shawn Getty

Powertrain Innovation Requires Infrastructure Innovation!

2012-04-10
Who are the people who know the most about the buses in your fleet? They are most likely the operators and the servicing technicians. They are also the key people whose knowledge, level of training and attitude can determine the success or failure of new powertrain technologies. Training and recruitment of both need to be held to a higher standard than we have seen in the past. I will argue that even the culture of those involved in fleet operations needs to be changed. The bar for technical competence and product knowledge needs to be raised for operators and technicians. In return managers should find ways to include them as stakeholders, investing them with both additional responsibility and accountability. This will require greater access to training and recognition of achievement. Where are the busses stored and serviced? Most likely in an all-purpose state/county/municipal service facility servicing a variety of equipment.

Vapor-Handling Capacity of Automobile Fuel Systems

1933-01-01
330014
THIS report covers information obtained on vapor lock, fuel-line temperatures and vapor-handling capacity as the result of road tests with 46 cars. The investigation was conducted under the auspices of the Cooperative Fuel Research Steering Committee in cooperation with the Natural Gasoline Association of America. The general procedure consisted in operating the car with samples of gasoline of increasing vapor pressure until vapor lock occurred. The development of a method for the evaluation of the vapor-handling capacity of fuel systems under various operating conditions has been of material assistance in analyzing the vapor-lock problem. The present work indicates that changes both in fuel-line temperatures and in vapor-handling capacity affect the permissible vapor pressures. It is still believed that lowering of fuel-line temperatures by changes in design of the fuel system is the most effective method of insuring freedom from vapor lock.

Further Investigation of Fuel Injection in an Engine Having Spark Ignition

1932-01-01
320026
THIS INVESTIGATION of fuel injection with spark ignition is a continuation of work previously reported,3 which was carried on in the aeronautic-engine laboratory of the Massachusetts Institute of Technology. Although a four-cycle engine was used, the fuel was injected during the compression stroke so that the results might be applicable to the two-stroke cycle without possibility of loss of fuel through the exhaust. Among the effects studied were those of stratification and of late injection or late ignition as a means of controlling detonation with high compression. Fuels used were aviation gasoline, ordinary Diesel fuel and hydrogenated fuel oil, the last seeming to offer interesting possibilities. Directed turbulence was found to be essential for good distribution of the fuel in the cylinder and satisfactory operation of the engine.

The Gum Stability of Gasolines

1932-01-01
320008
AN investigation of the accelerated oxidation method for predicting the gum stability of gasolines was made to determine the effects of oxygen pressure and of temperature on the observed induction periods. The data obtained on the effect of pressure indicated that there was a definite relation between the induction period at any pressure and the induction period at an air pressure of 1 atmosphere. The data obtained on the effect of temperature showed that the induction periods of different gasolines changed to a different extent with temperature, so that gasolines with the same induction period at any one temperature might have very different periods of stability at storage temperatures. Since temperature has a marked effect on the observed induction period and since the gasoline is at a lower temperature than that of the bath for a considerable period of time at the beginning of the experiment, a correction factor was applied to obtain true induction periods at the bath temperature.

Automobile Fuel-System Design and Vapor Lock

1932-01-01
320039
TEMPERATURE rise in the gasoline as it passes through the fuel system is the important factor in vapor lock that is within the control of the car designer. Gravity and vacuum-tank feed systems are considered briefly, including tests showing that weathering of the gasoline in the vacuum tank consists largely in removal of propane. Vapor lock in a pump system is most liable to occur on the suction side, because of the difference in pressure. Increasing the capacity of the pump for handling vapor offers little relief. Evidence is presented to show the gain made by locating the fuel line where it is protected from the heat. One example is cited to show the advantages of keeping a large flow of hot engine oil away from the pump. It is advantageous also to locate the pump where it will be cooled by the air entering the engine compartment of the car.

Fuel Injection with Spark Ignition in an Otto-Cycle Engine

1931-01-01
310005
THIS investigation was carried out in the aeronautical-engine laboratory at the Massachusetts Institute of Technology to determine the practical value of the use of a fuel-injection system in place of a carbureter on an Otto-cycle engine using spark ignition. Gasoline was used for most of the investigation, but comparative tests were also made using fuel oil. The equipment used was a single-cylinder laboratory-test engine and such other apparatus as was necessary for a complete performance test. A Diesel-engine injection-pump was used. A Diesel-type injection valve was used for injection into the inlet manifold, and a valve of special design, giving fine spray and little penetration, was used for the tests in which the injection was into the cylinder.

Fuel-Line Temperatures in Cars of 19311

1931-01-01
310018
THE PRESENT PAPER covers the results obtained in a second survey of fuel-line temperatures. Road tests were made on a large number of 1931 cars operated under various specified conditions, and fuel temperatures were measured in each case at several points in the fuel-feed system. On the average, no material improvement over the 1930 models was found. Individual models had been improved considerably, while others had become worse. This unchanged situation may be due, in part, to the fact that the results of the 1930 survey were not available in time so that full advantage could be taken of the conclusions in designing the 1931 models. Reasonable protection for most of the 1931 cars as regards fuel cannot be obtained in hot weather if they are run on gasolines having a Reid vapor pressure higher than 7 lb. per sq. in.

A Survey of Current Automobile and Bus Fuel-Line Temperatures1

1931-01-01
310017
PREVIOUS work on vapor lock at the Bureau of Standards under the auspices of the Cooperative Fuel Research Steering Committee has resulted in considerable information regarding the relation between the properties of gasolines and vapor lock and between fuel-line design and vapor lock. Satisfactory means have been developed for predicting the conditions under which vapor lock would occur with a given fuel, but no extensive information has been available on the gasoline temperatures existing in the fuel feed lines of automotive equipment. This has made it very difficult for the refiner to supply satisfactory fuels for current automotive equipment. The present report includes temperature data obtained at several points in the fuel feed systems of 27 automobiles and 8 buses under various operating conditions.

RECENT DIESEL-ENGINE DEVELOPMENTS

1925-01-01
250038
What the Diesel engine has done, its possibilities of development and future application to automotive service are major topics of the paper. When modified for automotive use, the author asserts that the Diesel engine would not only allow the burning of cheaper fuel and provide greater fuel economy, but give immediate opportunity to use the two-stroke cycle; that is, it would generate about twice the power for an equal weight of mechanism, compared with present power attainment. In addition, the two-stroke cycle makes possible partial or entire elimination of exhaust-valves, exhaust through ports being better in every respect, and the Diesel-engine principle affords the possibility of a two-stroke-cycle double-acting engine in which, theoretically, four times the power of the present gasoline engine would be available.
