Alternative-fuel engine manufacturing partnership Cummins Westport Inc. recently announced the formal certification from the United States Environmental Protection Agency (US EPA) for its ISL G engine.

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 uses Cummins' Exhaust Gas Recirculation (EGR) to delivering ultra low emissions. Also, with ratings from 250 to 320 horsepower, the ISL G will deliver increased thermal efficiency and over 30% higher low-speed torque compared with today's CWI "Plus" engines. Cummins Westport has received over 500 orders from U.S. transit properties, including Sacramento Regional Transit and the Orange County Transportation Authority (OCTA).
