Core Features and Advantages

Excellent Heat Resistance and Strength

Made from eutectic silicon aluminum alloy through forging and special heat treatment processes, significantly improving the piston's resistance to deformation and mechanical strength in high-temperature combustion environments, effectively preventing crown cracking.

Optimized Skirt Design

The piston skirt features a precision profile design (barrel-shaped and oval) combined with a low-friction coating, effectively reducing the friction coefficient between the piston and cylinder liner, lowering oil consumption, and preventing cylinder scoring.

Efficient Heat Dissipation Performance

The piston interior incorporates a unique cooling oil gallery (oscillating oil cooling) to accelerate heat transfer, ensuring piston crown temperature remains within safe limits and extending service life.

Precision Machining and Tolerance Control

Manufactured strictly according to Cummins original technical standards, with critical dimensions such as pin bore position and ring groove flatness precision-ground to ensure perfect fit with connecting rod bushings and piston rings.
