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_x 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.

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 NO_x 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.

The Energy Smart Guide to Campus Cost Savings

7/1/2003

With 4,000-plus accredited, degree-granting institutions of postsecondary education in the U.S. and its outlying areas, energy efficiency improvements are impacting millions of students, faculty and staff. NACUBO and APPA are proud to have worked with the United States Department of Energy to bring you this resource guide, which is intended to give our members realworld input on a number of critical energy efficiency issues facing us today. It's also meant to alert our members to new opportunities to save both money and energy, while strengthening your institutions' contributions to environmental responsibility. And as such, it is part of our continuing services to our members. Our goal, as always, is to bring you up-to-date information you can use to make the difficult and important decisions that you face every day.

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.
