Overview
The cylinder liner, also known as the cylinder sleeve, is one of the core components of an internal combustion engine. It is a cylindrical part that is fitted into the cylinder block itself. Together with the piston and cylinder head, it forms the combustion chamber. The cylinder liner provides guidance for the reciprocating motion of the piston and is responsible for transferring the heat generated during combustion to the cooling medium.
Main features
-
Excellent wear resistance: The inner wall of the cylinder liner is in direct friction with the piston rings that move at high speeds; therefore, materials such as phosphorus- and boron-containing wear-resistant alloy cast irons (e.g., HT25-47) are commonly used for their manufacture. For some products, the inner surface undergoes special treatments such as chrome plating or nitriding to further enhance their wear resistance.
-
Excellent thermal management performance: As a key pathway for heat conduction, the cylinder liner can promptly dissipate the high temperatures generated by the piston assembly. Its structural design directly influences the engine’s thermal management efficiency.
-
Sufficient mechanical strength and precision: The cylinder liner must withstand the high pressure generated during combustion, the lateral thrust from the piston, and thermal stresses; therefore, it must possess adequate strength and rigidity. At the same time, its inner bore must exhibit high roundness, cylindricity, and an appropriate surface roughness to ensure sealing performance and the formation of a good oil film.
Application areas
Cylinder liners are widely used in various types of power machinery whose operation hinges on pistons, and they are critical components that determine the machinery's performance and service life.
-
Transportation sector: Includes engines for automobiles (gasoline and diesel engines), ships, locomotives (internal combustion locomotives), and construction machinery.
-
Industrial and agricultural sectors: various generator sets, agricultural diesel engines, air compressors, and certain petrochemical machinery.

Engine valves are the core components of the valve train system. They are manufactured from high-temperature-resistant alloy materials and come in two types: intake valves and exhaust valves. These valves are suitable for gasoline and diesel engines with different numbers of cylinders, serving as critical components for controlling engine intake and exhaust.
These are engine crankshaft bearings (bearing shells), which are the core wear-resistant components for the crankshaft area of an engine.
The engine connecting rod is one of the key components of the engine's transmission system.
