City of Los Angeles Bureau of Sanitation LNG Heavy-Duty Trucks
2/1/2004
This fact sheet describes an Advanced Vehicle Testing Activity (AVTA) field study for Dual-Fuel? liquefied natural gas (LNG) refuse trucks used by the City of Los Angeles Bureau of Sanitation. The study showed that the trucks with Dual-Fuel engines were best suited to meet the operational requirements of refuse collection. Specifically, the Dual-Fuel trucks had adequate horsepower and torque and could be operated safely over all terrains covered by the Bureau's refuse collection service.
Demonstration of a Low-NO<sub>x</sub> Heavy-Duty Natural Gas Engine
2/1/2004
This project demonstrated a heavy-duty natural gas engine emission reduction strategy resulting in oxides of nitrogen (NOx) emissions of 0.54 g/bhp-h and particulate matter (PM) emissions of 0.004 g/bhp-h. Reducing NOx and PM emissions is crucial for meeting increasingly strict regulations (Figure 1). By 2010, the U.S. Environmental Protection Agency (EPA) will require NOx emissions of 0.2 g/bhp-h or less and PM emissions of 0.01 g/bhp-h or less. The technology demonstrated in this project may help natural gas engines meet the 2010 requirements. It is anticipated that this would lead to more extensive use of natural gas vehicles, resulting in reduced petroleum consumption.
Clean Cities Alternative Fuel Price Report - December 30, 2003
12/30/2003
This is the tenth issue of the Clean Cities Alternative Fuel Price Report, a quarterly newsletter keeping you up to date on the price of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue discusses prices that were gathered from Clean Cities coordinators and stakeholders during the weeks of December 1, and December 8, 2003, with comparisons to the prices in the previous Price Report, which were collected in February 2003.

Travel Matters: Mitigating Climate Change with Sustainable Surface Transportation
11/7/2003
TRB's Transit Cooperative Research Program (TCRP) Report 93: Travel Matters - Mitigating Climate Change with Sustainable Surface Transportation presents information on climate change and examines how greenhouse gas emissions from transportation may be reduced. The report also looks at the capacity of public transportation to mitigate greenhouse gas emissions.

The Next Generation Natural Gas Vehicle Activity
9/1/2003
The Next Generation Natural Gas Vehicle (NGNGV) R&D activity is leading important advances in natural gas vehicle (NGV) technology. NGNGV Phase I engine research projects demonstrated NOx emissions well below EPA 2007 levels, and tow projects met EPA 2010 levels in medium-duty engines. NGNGV Phase II engine and vehicle projects covering a range of power and torque ratings are targeted to achieve EPA 2007/2010 emission levels in 2005. In addition, gaseous fuel expertise gained through the NGNGV activity and other government and industry NGV and infrastructure efforts is aiding the transition to a future transportation scenario based on hydrogen.
On-Road Development of the C-Gas Plus Engine in Heavy-Duty Vehicles
6/1/2003
To advance NGV technology, DOE's National Renewable Energy Laboratory (NREL) supported on-road protoype development of the C-Gas Plus engine, beginning in November 2000. The goal of the project was to advance laboratory-developed technologies, on road and in service, for a natural gas truck and bus engine with significant improvements over the previous C8.3G natural gas engine. This goal was achieved. The C-Gas Plus was launched into production in July 2001 with increased engine ratings, reduced emissions, and lower cost compared with the C8.3G engine.
An Emission and Performance Comparison of the Natural Gas C-Gas Plus Engine in Heavy-Duty Trucks: Final Report
4/1/2003
To advance NGV technology, DOE's National Renewable Energy Laboratory (NREL) supported on-road prototype development of the Cummins Westport Inc. (CWI) C8.3G Plus (C-Gas Plus) compressed natural gas engine, beginning in November 2000. The goal of the project was to advance laboratory-developed technologies, on road and in service, for a natural gas truck and bus engine with significant improvements over the previous C8.3G natural gas engine. This report summarizes on-road prototype development of the C-Gas Plus engine.
