Cummins Westport First Off the Mark - 2010 EPA Certification for 2007 ISL G Natural Gas Engine

Tuesday, 10 July 2007

Canada, Vancouver

Cummins Westport Inc. (CWI), has received formal certification from the United States Environmental Protection Agency (US EPA) certifying their ISL G engine 2010 standards of 0.2g/bhp-hr oxides of nitrogen (NOx) and 0.01 g/bhp-hr particulate matter (PM). “The ISL G is the world’s first heavy duty engine for urban bus and truck applications to be certified to the 2010 EPA standard,” said Guan Saw, President of Cummins Westport. “With improved low end torque and maintenance-free after treatment, the ISL G will deliver diesel-like performance and reliability and the opportunity for customers to take advantage of the lower cost of natural gas.”

About the Cummins Westport ISL G
 
The ISL G surpasses EPA 2007 phase-in levels and meets 2010 emission standards of 0.2 g/bhp-hr NOx and 0.01 g/bhp-hr PM. Based on the Cummins ISL, the ISL G leverages Cummins proven Exhaust Gas Recirculation (“EGR”) with stoichiometric combustion allowing for the use of a three way catalyst, which is maintenance free and is in common use in passenger cars.  In addition to delivering ultra low emissions, the ISL G, with ratings from 250 to 320 horsepower, will deliver increased thermal efficiency and over 30% higher low-speed torque compared with today’s CWI “Plus” engines. Cummins Westport has already logged over 500 orders for the ISL G from U.S. transit properties, including Sacramento Regional Transit and the Orange County Transportation Authority (OCTA).
