The function of the cylinder head

The cylinder head is also equipped with an intake and exhaust valve seat, valve conduit holes for installation of intake and exhaust valves, as well as intake and exhaust channels, etc. The cylinder head of a gasoline engine is machined with a hole for installing the spark plug, while the cylinder head of a diesel engine is machined with a hole for installing the fuel injector. The cylinder head of the overhead camshaft engine is also machined with a camshaft bearing hole for mounting the camshaft.
The cylinder head is generally cast with gray cast iron or alloy cast iron. The good thermal conductivity of aluminum alloy is conducive to improving the compression ratio.
The cylinder head is a component of the combustion chamber. The shape of the combustion chamber has a great influence on the work of the engine. Because of the different combustion modes of the gasoline engine and the diesel engine, the parts of the cylinder head composed of the combustion chamber differ greatly. The combustion chamber of a gasoline engine is mainly in the cylinder head, while the combustion chamber of a diesel engine is mainly in the pit on the top of the piston.
