188F cylinder head, GX390 cylinder head, GX420 cylinder head, GX460 cylinder head
The 188F series cylinder heads match GX390 engines, GX420 engines and GX460 engines. The essential difference is capacity. The cylinder head is made of gray cast iron or alloy cast iron, but in recent years, because aluminum alloy has good thermal conductivity and can improve the compression ratio, the use of aluminum alloy cylinder head is more and more widespread. As a part of the combustion chamber, the shape of the cylinder head has an important impact on the work of the engine. Because of the different combustion modes of gasoline engine and diesel engine, the parts of the combustion chamber on the cylinder head are also very different.
