PACCAR has unveiled MX engine which is to be installed in Kenworth and Peterbilt trucks this summer. The engine is available with a horsepower range of 380hp-485hp and torque outputs up to 1,750 lb-ft.
The company claims that this power range, combined with fuel efficiency, reliability, durability, lightweight design and low cost of ownership, makes it suitable for both over-the-road line-haul and vocational applications.
Jim Cardillo, president of PACCAR, said: “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. Over 125,000 PACCAR MX engines are successfully operating in DAF trucks globally.
“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 new engine uses Selective Catalytic Reduction (SCR) in combination with exhaust gas recirculation (EGR) to meet the EPA 2010 diesel engine emissions regulations.
Craig Brewster, assistant vice president of PACCAR, said: “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.”
