Products Description
The Cummins QSM11 Diesel Motor is a 12-liter six-cylinder diesel power platform designed for ship propulsion, construction machinery (such as cranes, road rollers) and large industrial generator sets. Through the integration of the fully electronically controlled high-pressure common rail system and the lightweight and high-rigidity structure, it achieves a wide range of output of 450-600 horsepower, with a torque density that is 18% higher than similar products. It also meets the IMO Tier III/EPA Tier 4 Final emission standards, taking into account both explosive power and sustainability.
