Description

TECHNICAL FIELD

[0002] The engine cylinder needs to be cleaned during production to remove fine debris, dust and oil stains on the surface of the engine cylinder, and the engine cylinder needs to be dehydrated and dried. Before cleaning, the burrs in the main oil passage hole need to be treated. If the burrs remain in the main oil passage hole, the burrs will block the hydraulic tappet along with the engine oil entering the HVA hole, causing the camshaft to seize and the OCV valve to fail. If the burrs fall on the cylinder head gasket during assembly, it will cause engine gas leakage, oil and water leakage, oil and water mixing and other problems, thereby causing the engine power to decrease, the emission to exceed the standard, and even the engine to fail, etc. Therefore, the burrs on the engine cylinder directly affect the overall quality of the parts.
