Internal combustion engine

The main components of an internal combustion engine include: cylinders, pistons, crankshafts, connecting rods, valve trains, and ignition systems. As the core of the power system, the quality of these components directly affects the engine’s performance, safety, and environmental friendliness. Therefore, strict quality control (QC) plays a critical role throughout the entire lifecycle of internal combustion engine design, manufacturing, and operation.

Pistons

The piston is the core moving component of an internal combustion engine; its dimensional accuracy, geometric tolerances, and material properties directly affect the engine’s combustion efficiency, sealing performance, durability, and vibration and noise levels.
