Engine Cylinder Head

What is an Engine Cylinder Head?

You will find the cylinder head of your engine at the top end of the engine cylinder, which aids to cover the cylinder bore. Basically, it includes inlet and exhaust valves to add new charge (air-fuel mixture) and to exhaust burnt flue gases. In case of a diesel engine the cylinder head of an engine contains nozzle to spray the fuel into a highly atomized form. But, if your vehicle contains a petrol engine, then you will find that the cylinder head includes a spark plug as an additional part of the engine, which aids to ignite the charge.

Steel or aluminum alloys are used to cast the cylinder head, and it is casted as a single piece for a cylinder. Asbestos gasket is used in between the bolted joint of cylinder head and cylinder to make cylinder head air tight in its place.
