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.

Fuel injector

The fuel injector is a core component of the engine’s fuel system; its dimensional accuracy directly affects fuel atomization quality, injection patterns, and combustion efficiency. The inspection of nozzle orifice roundness is a critical step in fuel injector quality control, and its importance stems from its direct impact on fuel atomization, injection accuracy, and engine performance.
