Overview

The cylinder head is one of the key components of the engine and plays an important role. It is the top sealing structure of the engine combustion chamber, providing the necessary space and support for the combustion chamber.

Function

The cylinder head is one of the key components of the engine, and its functions mainly include the following aspects:

1. Close the top of the cylinder to form a combustion chamber.

2. Together with pistons, crankshafts and other components, it forms the mechanical system of the engine to complete energy conversion.

3. Withstand the working environment of high temperature and high pressure to ensure the normal operation of the engine.

Materials

The cylinder head needs to withstand high temperature and high pressure working environment, so it needs to use high-performance materials to manufacture. Common cylinder head materials are cast iron, aluminum alloy and so on. Cast iron cylinder head has good high temperature resistance, while aluminum alloy cylinder head has the advantages of light weight and good thermal conductivity. With the development of technology, some high-performance engine cylinder heads also use more advanced materials, such as high-strength alloy steel.

Production process

Cylinder head production process is more complex, including casting, machining, heat treatment and other steps. Casting is the basis of cylinder head production, and its quality directly affects the subsequent processing and engine performance. Machining is the precise processing of the cylinder head after casting to ensure its size and shape accuracy. The heat treatment is to improve the strength and corrosion resistance of the cylinder head.
