Paccar MX 12.9l Engine Gets EPA Certification

Engine manufacturer Paccar announced yesterday it has received the Environmental Protection Agency's (EPA) certification for the Paccar MX 12.9l diesel engine, an unit which will be fitted into future Kenworth and Peterbilt trucks.

“The EPA certification is an important milestone in establishing the PACCAR MX engine in North America,” Jim Cardillo, Paccar president said in a statement. “The proven performance of the Paccar MX engine will deliver outstanding reliability and durability, as well as excellent fuel efficiency and lower operating costs to our customers. Over 1,500 Kenworth and Peterbilt vehicles with MX engines have been ordered.”

The MX unit will be made available with power outputs ranging between 380 to 485 and torque levels reaching 1,750 lb-ft. According to the engine maker, the unit has been subjected to tests equivalent to traveling 50 million miles on the roads, including through hot and cold temperature extremes, high altitudes and difficult vocational applications.

According to the EPA findings, the MX engine meets oxides-of-nitrogen (NOx) requirements for the 2010 EPA diesel engine emissions regulations: 0.2 grams per brake horsepower hour of NOx and 0.01 grams per brake horsepower hour of particulate matter.

“Paccar customers have benefited from the superior performance of the Paccar MX engine in DAF vehicles for years,” Mark Pigott, Paccar CEO added. “Kenworth and Peterbilt customers will now be able to enjoy the industry-leading reliability, fuel economy and resale value of world-class vehicles with PACCAR MX engines.”
