Function of Engine Cylinder Liner Kit


1] Sliding surface for the movement of piston:-

The cylinder liner acts as a reciprocating surface for the piston. The surface of the cylinder liner is smoother, therefore the piston can easily slide inside of the cylinder liner. And thus the cylinder liner requires less amount of lubrication.

Because of the highly finished surface of the liners, the rate of wear of the surfaces of piston rings due to the friction is also reduced.

2] Helps to transfer heat:-

The dry liners transfer heat directly to the engine block while the wet liners transfer heat to the coolant fluid to lower the temperature of the engine to optimum working temperature.

3] Provider better sealing:-

The smooth surfaces of the cylinder liner along with piston rings forms better sealing, thus it reduces the leakage during the compression and the leakage of exhaust gases.

4] It withstands the combustion:-

The cylinder liner withstands high temperature and pressure during the combustion process, therefore the engine block never experiences the higher stresses.

5] The cylinder liner undergoes wear and tear to protect the cylinder block from damages.

Agricultural Machine



Advantage of Engine Cylinder Liner Kit

  • Greater resistance. Making liners separately from the engine block allows the use of special higher performance materials than those used for the construction of the block itself. Liners are generally made in special cast iron alloys containing elements with natural lubricating properties, like graphite. Other components are added like chrome, vanadium, and molybdenum to help ensure resistance to corrosion and wear caused by high temperatures.


  • Easier maintenance. When liners are worn they can be replaced more easily than changing an entire cylinder block.


  • Higher thermal conductivity. At operating temperatures the liners heat up more than the cylinders and must be able to expand in both diameter and length. If they were cast together with the cylinders, the resulting thermal loading would be high enough to fracture the materials.


  • Less risk of defects. The more complex a casting, the more difficult it is to achieve perfectly even surfaces with low residual stresses.
