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.

Crankshaft

The crankshaft is the most critical component in an engine. Its quality directly affects power output, vibration and noise levels, and the overall service life of the engine. The roundness, cylindricity, and surface roughness of the main and connecting rod journals ensure the formation of a stable, uniform, and appropriately thick lubricating oil film between the journals and the bearings. This is the foundation for achieving effective lubrication, minimizing friction and wear, distributing load
