Cummins Inc. announced Aug. 23 it submitted its third engine for certification under the Environmental Protection Agency's (EPA) strict new diesel emission standards, which take effect Oct. 1.

The heavy-duty, 11-liter ISM engine will be certified to EPA standards that were agreed to by engine manufacturers in 1998.

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

On April 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 Aug. 15.
