About the product

The tightening requirements for cylinder head bolts are

The tightening requirements for cylinder head bolts mainly include accurate torque, appropriate material selection, correct installation position and quantity, and correct tightening sequence.

Torque requirement: The tightening torque of the cylinder head bolts must be accurate. Excessive torque may cause bolt deformation, while insufficient torque may cause bolt loosening, affecting the normal operation of the engine. The specific torque value depends on the size of the bolt and the type of engine, usually ranging from 7-10 N · m to 170-190 N · m.

Material selection: The material selection of cylinder head bolts is also crucial. Different materials have different properties, and suitable materials need to be selected according to specific situations. For example, cylinder head bolts made of cast iron usually have high strength and wear resistance, while cylinder head bolts made of aluminum alloy require more attention to their deformation and damage issues.

Installation position and quantity: Insufficient bolt quantity can lead to a decrease in the sealing performance of the cylinder head, while excessive bolt quantity can affect the performance of the engine. Therefore, the control of installation location and quantity is also part of the tight requirements.

Tightening sequence: The correct tightening sequence can avoid damage and deformation of bolts, ensuring the sealing between the cylinder head and cylinder bore. Generally speaking, tightening should be done in a diagonal pattern, starting with the bolt in the upper left corner, followed by the bolts in the lower right corner, lower left corner, and upper right corner. This process should be repeated alternately until all bolts reach the specified torque or angle.
