Paccar Inc. is expanding its range of diesels in North America with the introduction of the 10.8-liter MX-11 engine.

The new engine weighs about 400 pounds less than the larger MX-13, and the MX-11 has six ratings from 355 to 430 hp with torque of 1,250 to 1,550 lb-ft., the company said.

Paccar launched its 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 MX-11 has double overhead camshafts, a common rail fuel system with injection pressures of 36,000 psi, and a “lube module” with two replaceable filter elements.

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.

The new engine will be available in Kenworth and Peterbilt trucks and tractors in January 2016.
