Cummins receives official 2002 certification
Engine maker Cummins Inc. has announced that EPA has officially certified the company's ISX diesel engine to the 2.5-gram NOx + NMHC standard that goes into effect in October. EPA also affirmed the use of Auxiliary Emissions Control Devices (AECD) to protect the engine under certain operating conditions.
Columbus, IN-based Cummins said performance of its new 2002-compliant ISX engines will be improved in terms of engine braking capability and overall engine responsiveness. The company added that it plans to refine its 2002 ISX engine design to look for further improvements in fuel economy and reliability.
Cummins said it began field tests of the ISX engine in December 1999 and will have accumulated over 6 million miles of on-highway vehicle field-testing and 115,000 hours of laboratory tests by October.
