COLUMBUS — PACCAR announced that the Environmental Protection Agency (EPA) has certified the PACCAR MX 12.9-liter diesel engine to the 2010 emission standards. The PACCAR MX engine certification and compliance with EPA 2010 emission regulations allows the PACCAR MX engine to be installed in Kenworth and Peterbilt vehicles in North America, effective immediately.
“The EPA certification is an important milestone in establishing the PACCAR MX engine in North America,” said Jim Cardillo, PACCAR president. “Over 1,500 Kenworth and Peterbilt vehicles with MX engines have been ordered.”
MX engine production in North America begins this summer at PACCAR’s new engine facility in Columbus. The PACCAR MX engine has completed over 50 million miles in an extensive testing program. In addition, the MX engines have successfully completed evaluation in hot and cold temperature extremes, high altitudes and difficult vocational applications.
PACCAR previously announced the use of selective catalytic reduction (SCR) with its MX engines to meet the oxides-of-nitrogen (NOx) requirements for the 2010 EPA diesel engine emissions regulations.
