Form a sealed space with the front end face of the cylinder block to prevent oil splashing or leakage, while avoiding external water vapor from entering and causing internal corrosion.

Sealed and leak proof: Form a sealed space with the front end face of the cylinder block to prevent oil splashing or leakage, while avoiding external water vapor from entering and causing internal corrosion.

Protective isolation: Isolate dust, sand, mud and other impurities from entering the timing system, protect the timing belt/chain and tensioner from pollution and foreign object impact, and prevent gear jumping or breakage caused by pollution.

Noise reduction and shock absorption: As a timing transmission component wrapped in a thin-walled structure for high-speed operation, it effectively reduces the mechanical noise generated by chain or belt transmission and improves the smoothness of operation.

Auxiliary support: Some designs integrate engine mount holes to assist in fixing the engine position, but usually do not bear the main power load.
