COLUMBUS, Ind. — Cummins has submitted its third engine for certification under the Environmental Protection Agency’s (EPA) strict new diesel emission standards.

Set to take effect on Oct. 1, the new standards were agreed to by engine manufacturers in 1998. Cummins is hoping its heavy-duty, 11-liter ISM engine will be certified to EPA standards in time for this deadline.

“We are committed to having our line of EPA compliant engines ready for our customers in October,” says Cummins executive director of marketing Thomas Kieffer. “We are on track to accomplish this.”

On Apr. 2, Cummins announced 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 on Aug. 15. The ISM engine, with ratings between 280hp to 385hp, complements the Cummins ISX product in meeting the needs of short-haul trucking, vocational, construction and bus customers.

“The ISM is a proven engine in the industry,” adds Kieffer. “We have simply added the same cooled exhaust gas recirculation subsystem that is used on the Cummins ISX and ISB engines. This approach provides customers with the most reliable and best performing engines in their class.”
