Diesel engine cylinder liner is an important part of the engine, installed in the cylinder body, with the piston, piston ring and other components together to form the combustion chamber of the engine. The role of the cylinder liner mainly includes the following aspects:

1. Provide a work surface
• The cylinder liner provides a smooth and wear-resistant working surface for the reciprocating movement of the piston, reducing friction and wear and ensuring smooth operation of the piston.

2. Seal the combustion chamber
• The cylinder liner and piston ring work together to form a sealed space that prevents high-temperature and high-pressure gas from leaking into the crankcase in the combustion chamber, thus ensuring the compression ratio and combustion efficiency of the engine.

3. Conduct heat
• The cylinder liner transfers the high temperature generated during the combustion process to the coolant or cylinder block through itself, thereby effectively reducing the temperature of the combustion chamber and preventing overheating from damaging the engine.

4. Support and guide
• The cylinder liner provides guidance to the piston and piston ring, keeping the direction of movement of the piston stable and ensuring that its reciprocating movement in the cylinder is coordinated with the rotation of the crankshaft.

5. Wear resistance and protection
• The cylinder liner, through its material and surface treatment technology, withstands high temperatures, high pressures and frequent friction and wear, while protecting the cylinder body from direct wear and extending engine life.

6. Easy to repair and replace
• The replaceable cylinder liner (wet or dry) used in some diesel engines can be replaced directly when the cylinder liner is worn or damaged, without replacing the entire cylinder block, reducing maintenance costs.

Classification of cylinder liner

According to the design and installation method, the cylinder liner is divided into the following two categories:
1. Wet cylinder liner
• Direct contact with coolant, good heat dissipation effect, but higher sealing requirements.
2. Dry cylinder liner
• Not in contact with the coolant, easier to install, but the heat dissipation performance is slightly worse than the wet cylinder liner.
