Cummins Westport Receives US$350,000 for Engine Demonstration

VANCOUVER, British Columbia--Feb. 6, 2006--Cummins Westport Inc. (CWI) today announced it will receive US$350,000 in funding from Utilization Technology Development (UTD) for engine development demonstration. UTD is an Illinois not-for-profit company that funds technology development and demonstration activities.

The funding will be applied to the customer demonstration for the next generation ISL G natural gas engine. The ISL G is commencing pre-commercial field trials in southern California and will be commercially available in 2007.

The Cummins Westport ISL G engine will surpass U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) 2007 levels and meet 2010 emissions standards of 0.2 g/bhp-hr oxides of nitrogen (NOx) and 0.01 g/bhp-hr particulate matter (PM) at launch in 2007, using cooled exhaust gas recirculation (EGR) and a passive three-way catalyst. Greenhouse gas emissions are expected to be 17% lower than the cleanest diesel engine available. The advanced engine is also expected to have improved thermal efficiency and power density relative to current natural gas engines.

"We feel this technology holds promise for increased efficiency as well as reduced emissions, and we're glad to support the advancement of technology that benefits all stakeholders," said Ron Snedic, UTD Program Administrator.

"We are very pleased to receive this financial support from Utilization Technology Development," said Guan Saw, President of Cummins Westport Inc. "The new ISL G engine has received tremendous support for its goals, meeting U.S. federal and local emissions regulations ahead of schedule, and providing customers with a real and economic transportation solution."

In May 20, 200604, Cummins Westport introduced the L Gas Plus, which is the platform for Cummins Westport's next generation natural gas engines, including the ISL G. The current L Gas Plus is rated at 320 horsepower and 1,000 lb-ft torque and is capable of meeting 2007 EPA standards for NOx and PM.
