Cummins High-Horsepower Engine Pistons

Product Overview

Cummins M11 series engine pistons are core combustion components developed exclusively for M11 full-electronic diesel engines (including Xi’an Cummins ISM11 and QSM11). M11 engines are widely equipped on heavy-duty trucks such as Shaanxi Delong and Auman, as well as various construction machinery.

These pistons are precision cast from eutectic aluminum alloy, featuring a unique ω-shaped combustion bowl on the crown that perfectly matches the atomization angle of fuel injectors. They deliver outstanding heat resistance, wear resistance and fatigue strength, able to withstand violent impacts from the engine’s peak firing pressure up to 15 MPa, ensuring efficient and stable power conversion.
