The cylinder head is one of the important parts of the engine. It is located above the automobile engine block and is used to close the top of the cylinder and is sealed with the cylinder block. The following are the structural features of the cylinder head .
1. Material: The cylinder head is usually made of aluminum alloy, because aluminum alloy has good thermal conductivity and lightweight characteristics, which can effectively dissipate heat and reduce the overall weight of the engine.
2. Heat sink: There are usually many heat sinks on the cylinder head to increase the heat dissipation surface area and improve the heat dissipation effect. The existence of the heat sink can dissipate the generated heat faster and maintain the normal operating temperature of the engine.
3. Valve and valve seat: There are multiple valves and corresponding valve seats on the cylinder head. The valve is a key component that controls the intake and exhaust of the cylinder, and the valve seat is used to support and fix the valve.
4. Combustion chamber: Part of the cylinder head is the combustion chamber, which is used to accommodate the high-temperature and high-pressure gas generated during the combustion process. The shape and design of the combustion chamber will directly affect combustion efficiency and power performance.
5. Throttle valve hole: Some engines have a throttle hole on the cylinder head to control the amount of air intake. By adjusting the opening and closing of the throttle valve, the power output of the engine can be controlled.
In general, the structural features of the cylinder head include lightweight materials, heat sink design, valve and valve seat arrangement, combustion chamber shape, and throttle hole setting. These features are all designed to improve the engine’s heat dissipation capacity, combustion efficiency and power performance.
