What is the function of a cylinder liner?

- Apr 13, 2020-

A cylinder liner is the central working part of a reciprocating engine or pump, the space in which a piston travels.

Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work. Cylinders may be sleeved (lined with a harder metal) or sleeveless. A sleeveless engine may also be referred to as a "parent-bore engine".

The main function of Cylinder liners are:

  1. Formation of sliding surface

  2. Heat transfer

  3. Compression gas sealing

Formation of sliding surface:

The cylinder liner, serving as the inner wall of a cylinder, forms a sliding surface for the piston rings while retaining the lubricant within. The most important function of cylinder liners is the excellent characteristic as sliding surface and these four necessary points.

  1. High anti-galling properties

  2. Less wear on the cylinder liner itself

  3. Less wear on the partner piston ring

  4. Less consumption of lubricant

Heat transfer

The cylinder liner receives combustion heat through the piston and piston rings and transmits the heat to the coolant.

Compression gas sealing

The cylinder liner prevents the compressed gas and combustion gas from escaping outside.
It is necessary that a cylinder liner which is hard to transform by high pressure and high temperature in the cylinder.
