Large displacement: While meeting the power requirements of heavy trucks, it ensures higher reliability, durability and safety of the engine.
High power: The maximum power reaches 420 horsepower, which meets the requirements of modern logistics for fast, efficient and safe.
Large torque: The maximum torque is 1650N.m, and the power is strong, which can meet the requirements of starting heavy trucks with heavy loads and going up long slopes.
Cummins PT fuel system, ultra-high injection pressure, ensures good atomization and complete combustion of the engine.
The high-efficiency Holset exhaust gas turbocharger can ensure more sufficient air intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.
The air-to-air cooling technology ensures more sufficient air intake and better fuel economy, STC separate timing system ensures better combustion under high and low load conditions.
It is easy to replace the wet cylinder liner and has good heat dissipation effect. The components of all models are highly versatile, highly serialized, and easy to maintain. The cylinder block and cylinder head adopt built-in pressure lubricating oil passages, which are compact in structure and low in failure rate. As a Cummins One of the main models of the family, the M11 engine has won high recognition from customers in various fields for its strong power, ultra-low fuel consumption, high reliability and low maintenance cost.
