Cummins announced it has received certification for its medium-duty ISB engine from the Environmental Protection Agency for meeting the Oct. 1 emissions regulations.

Cummins, which had its ISX engine certified several months ago, says it is on schedule to have a full product line available for customers by the deadline.
Addressing concerns in the marketplace about October ’02 engines, Cummins officials say the new 5.9-liter ISB engine will allow customers to maintain their maintenance intervals, get better performance and enjoy the same or better fuel economy.
The new ISB was introduced in Europe more than a year ago. To meet the EPA emissions standard, a cooled exhaust gas recirculation (EGR) subsystem was added. In addition to the base engine experience in Europe, the new ISB with the cooled EGR subsystemwill have more than one million field test miles by the time of production.
Limited production of the 2.5 gram compliant ISB has already started and will follow a managed ramp up to full production by October.
