The cylinder head is also equipped with inlet and exhaust valve seats, valve guide holes for installing inlet and exhaust valves, as well as intake channels and exhaust channels. 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, and the thermal conductivity of aluminum alloy is good, which 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 impact on the work of the engine, because of the different combustion methods of gasoline engines and diesel engines, the part of the cylinder head composed of the combustion chamber is different. The combustion chamber of gasoline engines is mainly on the cylinder head, while the combustion chamber of diesel engines is mainly in the pit on the top of the piston.
