Fill the microscopic pores between the cylinder block and the cylinder head to prevent the leakage of high-pressure gas in the combustion chamber, ensure the power output efficiency of the engine, maintain the normal compression ratio, and enable the engine to generate sufficient power. Prevent the leakage of coolant and lubricating oil from the joint surface between the cylinder block and the cylinder head. Prevent the coolant from entering the combustion chamber, which may lead to problems such as the engine "boiling over" and a decrease in power.
