What material is the engine cylinder head made of?
The engine cylinder head was generally made of aluminum alloy. The aluminum alloy had good thermal conductivity, which could effectively reduce the engine temperature and ensure that the engine would not be overheated during continuous high-speed operation. In addition, the aluminum alloy material could also reduce the weight of the entire engine and improve the acceleration performance of the car. The application of aluminum alloy engine cylinder head can improve the performance index of the entire engine, including improving fuel economy, engine power and response, reducing noise, vibration and impact, and improving the reliability and safety of the car.
cylinder head
The cylinder head was an important part of the engine. It was located above the cylinder block and was used to seal the cylinder and form the combustion chamber. It withstood the effect of high temperature and high pressure gas, as well as mechanical and thermal loads. The main function of the cylinder head was to maintain the shape of the cylinder and control the gas entering and leaving the cylinder and the effective use of fuel by sealing the cylinder. It also contained moving parts such as fuel sprayers and valve. The material of the cylinder head can be cast iron or aluminum alloy. According to the structure and type, the cylinder head can be divided into top type, single top type, double top type, etc. The cylinder head also had a cooling water jacket for cooling the high-temperature parts such as the combustion chamber. In short, the cylinder head plays an important role in the engine, such as sealing the cylinder, forming the combustion chamber, and supporting the valve distribution mechanism.
