Cummins Inc has received unconditional certification for its heavy-duty ISM engine from the Environmental Protection Agency (EPA). The approval certifies that the ISM complies with new emissions standards agreed upon by the industry.

The 11-liter ISM engine, ranging from 280 to 385 horsepower, complements the firm's ISX product in meeting the needs of short-haul trucking, vocational, and bus customers. Cummins also will offer the ISM in a limited 400 and 450 hp for motorcoach, recreational vehicle, and fire truck use.

This engine is included in the Uptime Guarantee program recently announced. Under the guarantee, if any part on a customer's ISX or ISM engine fails and can't be repaired within 24 hours, Cummins will reimburse the cost of a rental vehicle. The guarantee applies to ISX and ISM engines purchased between Oct 1, 2002, and March 31, 2003, with coverage from date of purchase through Dec 31, 2003.
