Cummins Westport granted $760,000 to apply near-zero PM technology to natural gas engines

VANCOUVER, Feb. 7 -- Cummins Westport Inc., a joint venture of Cummins Inc. and Westport Innovations Inc. (TSX:WPT), announced today that it has been awarded $760,000 (US$500,000) to test, optimize and demonstrate catalyzed particulate controls on low-emissions natural gas transit bus engines, with the goal of reducing particulate matter (PM) to non- detectable levels.

The funding, which is subject to contractual agreements, will be administered by California's South Coast Air Quality Management District (SCAQMD). Cummins Westport will lead the program with support from well-known experts in exhaust emission analysis from the University of Minnesota, the University of Wisconsin and the University of West Virginia. Results are anticipated to be available in 2004.

"The addition of catalyzed particulate controls will reduce PM emissions to virtually zero," said Hugh Foden, President of Cummins Westport. "We look forward to working with South Coast and our other partners to keep natural gas vehicles at the forefront of California's clean air initiatives."

Cummins Inc. is a global power leader in engines, electrical power generation systems and related technologies. Westport Innovations is the leading developer of natural gas fuel systems for diesel engines. Cummins Westport Inc., formed in 2001, develops and markets low-emissions alternative fuel vehicle engines manufactured by Cummins.
