Product Description
The function of the cylinder head
The cylinder head is installed atop the cylinder block, sealing the cylinders from above and forming the combustion chamber. It frequently comes into contact with high-temperature, high-pressure gases, thus enduring significant thermal and mechanical loads. In water-cooled engines, the cylinder head contains cooling water passages, with coolant holes at the lower end of the cylinder head connecting to those in the cylinder block. This facilitates the use of circulating water to cool the combustion chamber and other high-temperature components.
Cylinder heads are typically made of gray cast iron or alloy cast iron. Aluminum alloy exhibits excellent thermal conductivity, aiding in the enhancement of compression ratios. Consequently, in recent years, aluminum alloy cylinder heads have been increasingly utilized.
The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and withstand the action of high temperature and high-pressure gas. The cylinder head bears the mechanical load caused by the gas force and the tightening of the cylinder bolts, and at the same time bears a high thermal load due to contact with the high-temperature gas. To ensure a good seal of the cylinder, the cylinder head must neither be damaged nor deformed. For this reason, the cylinder head should have sufficient strength and rigidity.
