Development Status of the Detroit Diesel Corporation Methanol Engine

1990-09-01
901564
The development of the DDC methanol engine has been an evolutionary process, with each subsequent configuration showing significant durability and/or emission improvement over its predecessor. Sixty demonstration engines are now in service in the field, including fifty-four (54) urban bus engines, five (5) truck engines, and one (1) generator set engine. While nitrogen oxide (NOx) and particulate emissions from the methanol engine are inherently low, a durable solution to the effective control of hydrocarbon (HC) emissions has been an especially challenging area. The 1991 Federal urban bus transient emission standards (including 0.10 gm/bhp-hr particulate) have been met with several combinations of compression ratio, intake port height, exhaust valve cam profile, injector tip design, and electronic control strategies, and without exhaust aftertreatment devices or fuel ignition improvers.

Methanol Use in School Transportation, an Expedition Through the Mind Set of America

1995-08-01
951966
This paper is based on the procurement and operational experiences of a neat methanol powered school bus for use by a public school district in the southeastern portion of Pennsylvania. It will address the initial steps taken to secure state, federal and corporate funding for the project, and the obstacles that must be overcome when introducing an alternative fueled vehicle into a suburban school district. The intent of this paper is to inform individuals in similar positions of the benefits of switching from the conventional fuels to those that will meet the requirements of the Clean Air Act Amendments of 1990 (CAAA).

The Hybrid Electric Vehicle Team of Virginia Tech (HEVT) is participating in the 2009 - 2011 EcoCAR: The NeXt Challenge Advanced Vehicle Technology Competition series organized by Argonne National Lab (ANL), and sponsored by General Motors Corporation (GM), and the U.S. Department of Energy (DOE). Following GM's Vehicle Development Process (VDP), HEVT established team goals that meet or exceed the competition requirements for EcoCAR in the design of a plug-in extended range hybrid electric vehicle. ...Using E85 fuel (corn-based in North America for the 2015 timeframe), the well-to-wheels petroleum energy use and greenhouse gas emissions are reduced by 91% and 18% respectively when compared to the stock 4-cylinder gasoline-fueled vehicle.

American and European technology is being used to demonstrate the suitability of neat methanol as a fuel for transit buses. ...Project management and bus testing are performed by Acurex Corporation. Test data are being obtained on performance, fuel consumption, exhaust emissions, noise levels, and operational suitability. ...One of the coaches was obtained from General Motors Corporation and the other from M.A.N. in Germany. The GM coach employs a Detroit Diesel Allison 6V-92TA two-stroke-cycle engine, which burns methanol by compression ignition.

Aqueous Ethanol Fueled Catalytic Ignition Engine

1999-09-28
1999-01-3267
A naturally aspirated, three-cylinder, direct-injection diesel engine manufactured by Yanmar has been modified to operate as a homogeneous-charge, compression-ignition engine. This involved removing the fuel injectors, replacing them with catalytic elements located inside a small pre-chamber, and installing a pulse width modulated fuel injection system.

On-Road CO2 and NOx Emissions for a Heavy-Duty Truck with Hydrogen-Diesel Co-Combustion

2023-01-0281
Heavy-duty diesel trucking is responsible for 25%-30% of the road transportation CO2 emissions in North America. Retrofitting class-8 trucks with a complementary hydrogen fuelling system makes it possible to co-combust hydrogen and diesel in the existing internal combustion engine (ICE), thus minimizing the costs associated with switching to non-ICE platforms and reducing the barrier for the implementation of low-carbon gaseous fuels such as hydrogen.

The use of renewable fuels, such as biodiesel, in motor vehicle fuels is expected to grow rapidly in North America as a result of government mandates, both federal and state/provincial. Biodiesel is a fuel component made from plant or animal feedstocks through a trans-esterification process. ...In North America where a large geographic area experiences a cold climate, the poor low temperature properties of FAME and blends containing same (wax, gelling, and phase separation above the Cloud Point) could result in operability issues such as those experienced in Minnesota and Sweden. ...The low temperature operability was compared to laboratory tests: cloud point and Low Temperature Flow Test (LTFT) known as the best predictor of low temperature operability of North American diesel fuels for heavy duty diesel trucks. These results will provide guidance for blending biodiesel fuels to meet low temperature operability requirements in cold climates.
