What is the Function of a Cylinder Head?

[LeLillian]

Here is a relevant introduction to the cylinder head: The main function of the cylinder head is to seal the cylinder, forming a closed space, which allows the piston to properly compress fuel and the air-fuel mixture to generate power. The structure of the cylinder head is relatively complex, generally including intake valve seat holes, exhaust valve seat holes, valve guide holes, spark plug mounting holes, intake passages, exhaust passages, camshaft bearing holes, etc. Cylinder heads are typically made of gray cast iron, alloy cast iron, or aluminum alloy, and they are complex box-shaped components. Depending on their structural type, cylinder heads can be classified into integral, block, and monobloc types. Requirements for cylinder heads: 1. High stiffness and strength, resistant to deformation, ensuring sealing effectiveness. 2. Reasonable layout to ensure the normal operation of the engine. 3. Manufacturing processes must meet standards to prevent friction with other components. Symptoms caused by a damaged cylinder head: 1. Abnormal engine vibration. 2. Reduced vehicle power, unresponsiveness to throttle input, or even loss of power. 3. Engine knocking. Things to note during routine vehicle maintenance: 1. Perform maintenance as scheduled. 2. It is advisable to use high-quality fuel. 3. Replace consumable items such as engine oil and oil filters in a timely manner.
