Fuel Cell Hybrid Bus Lands at Hickam AFB
9/13/2004
A fuel cell hybrid electric bus was unveiled at Honolulu's Hickam Air Force Base in February 2004, becoming the first fuel cell vehicle in Hawaii and the first in the U.S. Air Force. The 30-foot flight crew shuttle bus will undergo 1 year of in-service data collection and evaluation, then will continue in routine service at the base.

Biodiesel Analytical Methods
7/31/2004
Biodiesel is an alternative fuel for diesel engines that is receiving great attention world wide. Although it attracts the most attention because it is renewable, it can be used either pure or in blends with diesel fuel in unmodified diesel engines, and it reduces some exhaust pollutants. It is also attractive because it can be produced easily from common feedstocks. However, the relative simplicity of biodiesel production can disguise the importance of maintaining high quality standards for any fuel supplied to a modern diesel engine. It is essential to the growth of the biodiesel industry that all fuel produced and sold meet these quality standards.

Biodiesel Production Technology
7/31/2004
Biodiesel is an alternative fuel for diesel engines that is gaining attention in the United States after reaching a considerable level of success in Europe. Its primary advantages are that it is one of the most renewable fuels currently available and it is also non-toxic and biodegradable. It can also be used directly in most diesel engines without requiring extensive engine modifications. The purpose of this book is to describe and explain the processes and issues involved in producing this new fuel.

Evaluation of Biodiesel Fuel in an EMD GP38-2 Locomotive
5/30/2004
This report documents results of fuel consumption and exhaust emission tests performed on a 2,000 hp EMD GP38-2 locomotive operating on four different fuels. No operational problems were observed by SwRI on any of the test fuels, and the locomotive engine was able to produce within 1% to 2% of full rated power while operating on the biodiesel blends. Locomotive tests were performed at the SwRI Locomotive Exhaust Emissions Test Center in October, 2000.

Development of the High-Pressure Direct-Injected, Ultra Low-NO<sub>x</sub> Natural Gas Engine: Final Report
5/1/2004
This project targeted development of a high-efficiency, low-emission natural gas engine for heavy-duty trucks. Specifically, it targeted the demonstration of a Cummins ISX engine using HPDI natural gas fueling and exhaust gas recirculation (EGR) meeting the following specifications:
- Peak torque of 1,650 ft-lb (2,236 N-m)
- Rated power of 450 hp (335 kW)
- Peak thermal efficiency of 40% with typical diesel part-load efficiency
- NOx emissions of 0.5 g/bhp-hr
- PM emissions of 0.1 g/bhp-hr
- Substitution of diesel with natural gas greater than 90% over the certification cycle
Testing and modeling of an otherwise unmodified Cummins ISX engine with EGR and HPDI fueling indicated that the program goals could not be met with the standard production hardware. Therefore, a turbocharger using a smaller trim compressor and a second EGR cooler were fitted to the engine along with an oxidation catalyst.
