The 10.8-liter PACCAR MX-11 engine is a combination of proven technologies and state-of-the-art innovations that improve fuel economy and durability. The new PACCAR MX-11 engine’s common rail system with injection pressures to 36,000 psi and dual overhead cam design help achieve a more precise combustion process. The PACCAR MX-11 engine is designed to be a high performance alternative to big block engines and still meet the demands of the weight sensitive pickup and delivery, linehaul and vocational heavy-duty truck applications. Achieving the goal of the lowest possible fuel consumption, highest durability, low emissions and noise levels is what the PACCAR MX-11 is all about.
