What is?
In the above cylinder head is mounted, and the upper seal cylinder defining the combustion chamber. It is often in contact with high pressure gas, thus subjected to high thermal and mechanical loads.

Characteristics
with the cylinder head intake and exhaust valve seat, valve guide holes for mounting intake and exhaust valves, and intake and exhaust passages and the like. Gasoline engine cylinder head machined with the spark plug mounting hole, and machining the cylinder head of the diesel engine injector mounting hole. The overhead camshaft engine cylinder head is also machined with camshaft bearing bore for mounting the camshaft.

Type
into gray cast iron or an alloy cast iron. The head is an integral part of the combustion chamber, combustion chamber shape greatly influence the work of the engine, due to the different combustion gasoline and diesel engines, the cylinder head portion of a larger difference in composition of the combustion chamber. Gasoline main combustion chamber in the cylinder head, a combustion chamber of the diesel engine and the main pits top of the piston.
