Cummins Westport set to beat emissions deadline

VANCOUVER, B.C. — Cummins Westport Inc. has partnered with the South Coast Air Quality Management District to develop new engine technology for natural gas engines.

The goal is to meet U.S. Environmental Protection Agency 2010 emissions standards early.

The plan is to develop a prototype engine based on the application of cooled exhaust gas recirculation (EGR) in conjunction with a simple after-treatment system to its current line of lean-burn, spark-ignited, natural gas engines.

The $2 million project will be conducted in cooperation with the Department of Energy and the National Renewable Energy in Columbus, Ind. at the Cummins Technical Center and in Vancouver at Westport’s engine development facility.

The program could have demo engines ready by 2005. The company is hoping that by 2010, its heavy-duty engines will see reductions in nitrogen oxide emissions (NOx) to 0.2 grams per brake horsepower hour, and particulate matter to 0.01 g/bhp-hr. Both are 90 per cent less than current standards, the company says.

Cummins Westport, a joint venture of Cummins Inc. and Westport Innovations, develops and markets low-emissions, alternative fuel engines for medium and heavy-duty truck and bus applications.
