Cummins Westport Natural Gas Engine Gets OK from EPA

July 16, 2007

VANCOUVER, BRITISH COLUMBIA, Canada --- Cummins Westport Inc., a provider of alternative-fuel engines for the global market, announced its ISL G engine for buses and trucks running on natural gas has met U.S. EPA standards. The engine received formal certification from the U.S. Environmental Protection Agency for 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 aftertreatment, 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." 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.
