Cylinder Head Cover

1.Overview of Cylinder Head Cover

There are  three types of cylinder heads include flathead, overhead valve and overhead camshaft cylinder heads, each of which can be made of cast-iron or aluminum material, depending upon the specific system in which they are being used in. Our Cylinder Head Cover is made of aluminum alloy. In general, aluminum alloy is lighter and has stronger heat dissipation potential than any other material. Meanwhile, Why choose aluminum alloy to be the material of cylinder head cover? Not only aluminum cylinder head cover can reduce the weight of the car, but also improve the heat dissipation effect of the engine.Cylinder head covers serve to seal off the cylinder head space from the outside of the engine. As a result of operation of the internal combustion engine, blow-by gases from the combustion process and oil droplets from the lubricant system of the engine are present inside the cylinder head.

A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber.

2.Advantages of Cylinder Head Cover

It conveys air and gasoline to the combustion chamber and serves as a cover for the cylinders. The main advantage of the cylinder head is to help the head gasket seal the cylinders properly so that they are able to build enough compression for engine operation.
