Cummins submits third engine for EPA nod

Cummins Inc has submitted its third engine for certification under the Environmental Protection Agency's (EPA) new diesel emissions standards, which took effect October 1. The heavy-duty 11-liter ISM engine will be certified to EPA standards agreed to by engine manufacturers in 1998.

Cummins announced April 2 that its ISX engine became the first engine certified to the new EPA 2.5-gram NOx+NMHC standard. Its medium-duty ISB engine received EPA certification August 15. The ISM engine, ranging from 280 to 385 horsepower, complements the Cummins ISX product.

The company also will offer a restricted 400- and 450-hp rating for the ISM for motorcoach, recreational vehicle, and fire applications.
