The cylinder gasket is installed between the cylinder head and the cylinder block. Its function is to ensure the sealing of the contact surface between the cylinder head and the cylinder block to prevent air leakage, water leakage and oil leakage.
The material of the cylinder gasket should have a certain elasticity and be able to compensate for the unevenness of the joint surface to ensure sealing. At the same time, it should have good heat resistance and pressure resistance, and will not burn or deform under high temperature and high pressure. The most commonly used cylinder gasket is the copper-cotton structure. Since the copper-cotton cylinder gasket has three layers of copper at the flange, it is less likely to deform when pressed than asbestos. Some engines also use a cylinder gasket with a woven wire mesh or a perforated steel plate as the skeleton in the center of the asbestos, and asbestos and rubber adhesive pressed on both sides.
Cylinder gasket When installing the cylinder gasket, first check the quality and integrity of the cylinder gasket, and align all the holes on the cylinder gasket with the holes on the cylinder block. Secondly, tighten the cylinder head bolts strictly according to the requirements in the manual. When tightening the cylinder head bolts, it must be done 2 to 3 times in a symmetrical sequence extending from the center to the surrounding areas, and the last tightening should be done to the specified torque.
