Construction of Cylinder Head
It is cast separated from the cylinder block to eliminate it for cleaning carbon and grinding valve. To maintain compression within the cylinder, a flat piece of gasket is arranged between the cylinder head and the cylinder block.
Function of Cylinder Head
The cylinder head plays an important role in a motor vehicle. The structure of the cylinder head is complex and consists of many ports. One of these ports is designed to work, and their common roles explain the value of this engine part.
