Cylinder liner for Perkins engines

The cylinder liner, part number 14-020870-00, acts as the internal wall of the engine block where the piston travels. It creates a controlled environment for the combustion process, housing the piston and rings to maintain proper compression within the cylinder. By providing a defined surface for the piston to slide against, the liner manages the heat transfer from the combustion chamber to the cooling system of the engine block.

This component is manufactured by Perkins for specific engine configurations. It is designed to fit precisely into the engine block to ensure proper alignment and sealing. The liner serves as a protective barrier, preventing direct contact between the moving piston and the engine block casting. Proper installation of this liner is necessary to maintain engine efficiency and prevent issues such as oil consumption or loss of power.

In heavy machinery and industrial engines, cylinder liners are used to allow for the maintenance of the cylinder bore without replacing the entire engine block. They are engineered to withstand the thermal and mechanical stresses inherent in internal combustion, facilitating the transfer of heat to the engine coolant while maintaining a consistent geometry for the piston assembly.
