The cylinder head is an important component of the engine, located at the top of the cylinder block and covering the cylinder. Here are some common information about cylinder heads:
Function: The cylinder head has multiple functions. Firstly, it seals the top of the cylinder, forming a combustion chamber that can accommodate a mixture of fuel and air. Secondly, the cylinder head carries components such as the cylinder liner, piston, connecting rod, and valve mechanism, and provides their support and guidance.
Material: The cylinder head is usually made of materials such as cast iron, aluminum alloy, or magnesium alloy. Aluminum alloy is the most common choice because it has lower weight, good thermal conductivity, and higher strength.
Heat dissipation and cooling: The cylinder head controls the temperature of the engine through heat sinks, coolant channels, and coolers. It helps transfer the heat generated by combustion to the coolant and reduces the engine's temperature by circulating the coolant, ensuring normal engine operation.
Valve mechanism: The cylinder head is equipped with valves and valve mechanisms. The valve is connected to the combustion chamber through the valve seat on the cylinder head, controlling the entry and exit of fuel and air. The valve mechanism includes components such as camshafts, rocker arms, and valve springs, used to control the opening and closing of valves.
Maintenance and repair: The cylinder head needs regular maintenance and inspection to ensure its normal operation. This includes checking valve clearance, replacing valve guides, cleaning coolant passages, etc. When maintenance is required, it may be necessary to disassemble the cylinder head for maintenance or replace components such as sealing gaskets.
Overall, the cylinder head is an important component of the engine, with functions such as sealing the combustion chamber, supporting and guiding components, heat dissipation and cooling. It is usually made of materials such as aluminum alloy and requires regular maintenance and inspection to ensure the normal operation of the engine.
