Product Application
The cylinder head gasket is installed between the cylinder head and engine block. Its main functions include:
- Combustion chamber sealing – Prevents high-temperature, high-pressure combustion gas from leaking, helping maintain compression pressure and power output.
- Oil and coolant separation – Isolates cooling water passages from oil galleries to prevent oil emulsification or coolant contamination.
- External leakage prevention – Seals the joint face to prevent coolant and oil from escaping to the outside.
- Force transmission and compensation – Transmits cylinder head bolt clamping force and compensates for microscopic surface irregularities and thermal deformation.
A damaged cylinder head gasket can lead to gas leakage between cylinders, coolant system aeration, oil emulsification, reduced engine power, overheating, or even engine failure. Regular maintenance and correct oil selection are recommended to help extend service life.
