This is an article about the introduction of auto parts engine cylinder head!!
The engine cylinder head is one of the most critical parts in the engine. It has high precision requirements and complex processing technology. The quality of the processing directly affects the overall performance and quality of the engine. Therefore, the processing of the engine cylinder head is particularly important. The machining of the conduit hole is even more important.
The cylinder head is installed on the top of the cylinder block, which seals the cylinder from the top and constitutes the combustion chamber. It is often in contact with high temperature and high pressure gas, so it bears a large thermal load and mechanical load. A cooling water jacket is made inside the cylinder head of the water-cooled engine, and the cooling water hole on the lower end face of the cylinder head communicates with the cooling water hole of the cylinder block. Use circulating water to cool high temperature parts such as the combustion chamber.
The cylinder head is also equipped with intake and exhaust valve seats, valve guide holes for installing intake and exhaust valves, as well as intake and exhaust passages. The cylinder head of a gasoline engine is machined with holes for installing spark plugs, while the cylinder head of a diesel engine is machined with holes for installing fuel injectors. The cylinder head of the overhead camshaft engine is also machined with a camshaft bearing hole for installing the camshaft.
The cylinder head is generally made of gray cast iron or alloy cast iron. The thermal conductivity of aluminum alloy is good, which is conducive to improving the compression ratio. Therefore, in recent years, aluminum alloy cylinder heads have been used more and more.
