? ? ? The main function of a cylinder head is to seal the cylinder block from the upper side using a head gasket. So, the leakage of the air-fuel mixture and burnt exhaust gases are totally arrested.
To admit a fresh charge of the mixture inside the cylinder block, Intake Valve is mounted on a cylinder head. While exhaust valve is mounted to escapes burnt exhaust gases to the atmosphere through the silencer.
A spark plug is mounted if the engine is spark ignition type (SI Engine). While in Compression Ignition type engine (CI Engine), a fuel injector is mounted on the cylinder head.
A cylinder head is usually made by casting or forging process in one piece of cast iron. Also in some cases, it is manufactured from aluminium.
