An engine cylinder head is an integral part of any internal combustion engine. One function of it is to close the top of the combustion chamber. Bolted to the engine block’s top, the cylinder head’s gasket seals off the combustion chamber. The spark plugs are usually in the cylinder head and ignite the air/fuel mixture.
The engine cylinder head has intake and exhaust runners, valves, oiling passages, and cooling passages. It also has rockers to open and close the valves, valve springs and may hold the camshaft(s). The cylinder head function allows the engine to breathe the air it needs for combustion and expel the exhaust gasses.
