Paccar said the new MX engine is designed to deliver industry leading performance, reliability, and fuel efficiency to Kenworth and Peterbilt customers worldwide.

The Paccar MX engine uses selective catalytic reduction (SCR) in combination with exhaust gas recirculation (EGR) to meet the EPA 2010 diesel engine emissions regulations. ''The combination of SCR and EGR provides Kenworth and Peterbilt customers with a highly efficient solution to meet the EPA's 2010 requirements. Paccar's world-class vehicles have successfully operated Euro 4 and Euro 5 certified SCR emission systems for several years,'' noted Dan Sobic, PACCAR executive vice president.

''Paccar's 50 years of engine development and manufacturing expertise have established the company as one of the leading diesel engine manufacturers in the world,'' said Jim Cardillo, Paccar president.

''Over 125,000 PACCAR MX engines are successfully operating in DAF trucks globally.'' Cardillo added, ''The Paccar MX is designed to meet the Environmental Protection Agency's (EPA) 2010 emissions regulations and has accumulated over 50 million test miles in rigorous and severe conditions in North America. PACCAR is pleased to be launching this proven, industry-leading engine in Kenworth and Peterbilt trucks.''

The Paccar MX engine is available with a horsepower range of 380hp-485hp and torque outputs up to 1,750 lb-ft. This power range, combined with excellent fuel efficiency, high reliability, durability, lightweight design and low cost of ownership makes it an ideal choice for both over-the-road line-haul and vocational applications, Paccar said.

''We look forward to delivering our integrated and optimised best-in-class drivetrain to our customers,'' said Craig Brewster, Paccar assistant vice president. ''The Paccar MX engine generates up to 485hp with excellent performance across a wide range of engine speeds. In addition to performance excellence, Paccar pioneered the design and manufacture of high-strength compacted graphite iron (CGI) used in the MX engine block and cylinder head.

"This premium material is more durable and lighter than conventional grey iron resulting in superior power-to-weight performance,'' added Brewster. ''The electronically controlled high pressure fuel injection system delivers excellent fuel economy and assists in achieving the low emissions required by the EPA. The engine's block design and rear gear train contributes to significantly lower in-cab noise levels resulting in a more comfortable driver environment. The integral engine brake provides powerful performance across a broad range of engine RPM's.''
