PACCAR is expanding its range of diesels in North America with the introduction of the 10.8-liter MX-11, based on a successful European engine.
The new engine weighs some 400 lb less than the larger MX-13, and has six ratings from 355 to 430 hp with torque ranging from 1250 to 1550 lb ft.
PACCAR launched the MX-11 in Europe in 2013, installing over 10,000 of them in DAF trucks in the last two years. Field testing has covered 2 million miles.
The engine combines what the maker calls “state-of-the-art innovations and proven technologies” that reduce weight and deliver features needed for a wide variety of over-the-road and vocational applications. It has double overhead camshafts and a common-rail fuel system with injection pressures of 36,000 psi.
It uses compacted graphite iron in its cylinder block and head, and claims a B10 life of 1 million miles for highway applications and 750,000 for vocational use. That means 90% of the engines will still be running at those points without overhaul.
The new engine will be available in Kenworth and Peterbilt trucks and tractors in January.
