Air piston cylinder

Air piston cylinder is the cavity in the cylinder block of the internal combustion engine where the piston is placed. It is the orbit of the piston movement, in which the gas burns and expands, and through the cylinder wall, it can also dissipate a part of the residual heat of the explosion transmitted by the gas, so that the engine maintains a normal working temperature.

Air pistons can generally be divided into single-acting cylinders, double-acting cylinders, diaphragm cylinders, impact cylinders and rodless cylinders.

A single cast cylinder barrel is called a cylinder liner. The cylinder liner that is in direct contact with the cooling water is called a wet cylinder liner; the one that is not in direct contact with the cooling water is called a dry cylinder liner.

In order to maintain the tightness of the contact between the cylinder and the piston and reduce the friction loss of the piston moving in it, the inner wall of the cylinder should have high machining accuracy and precise shape and size. Common air cyclinders are: DNC Series ISO6431 Standard Cylinder, SI Series ISO15552 Standard Cylinder, CQ2 Series Compact Cylinder.
