Cummins Westport Certified To 2010

Posted on July 12, 2007

Cummins Westport Inc. has received 2010 certification for its ISL G natural gas engine from the U.S. Environmental Protection Agency.

The ISL G engine which is based on Cummins Inc.’s ISL diesel platform meets the 2010 emissions requirements of 0.2g/bhp-hr NOx and 0.01 g/bhp-hr for PM. It combines Cummins EGR with stoichiometric combustion allowing for the use of a three way catalyst, which Cummins Westport said is maintenance free and commonly used in passenger cars. The ISL G has rating from 250 to 320 hp, increased thermal efficiency and over 30% higher low-speed torque compared with the company’s CWI “Plus” engines, the company said.

Cummins Westport has had over 500 orders for the ISL G from U.S. transit properties, including Sacramento Regional Transit and the Orange County Transportation Authority.
