Cummins Inc. has submitted its third engine for certification under the Environmental Protection Agency's (EPA) strict new diesel emissions standards, which take effect on October 1.
The heavy-duty 11-liter ISM engine will be certified to EPA standards that were agreed to by engine manufacturers in 1998.
The ISM engine, with horsepower (hp) ranging from 280-hp to 385-hp, will meet the needs of short-haul trucking, vocational, construction and bus customers.
"We have simply added the same cooled exhaust gas recirculation subsystem that is used on the Cummins ISX and ISB engines," said Thomas Kieffer, executive director of marketing.
Cummins will also offer a restricted 400-hp and 450-hp rating for the ISM, for motorcoach, recreational vehicle and fire applications.
