In a diesel engine, the liner (cylinder liner) is a critical component of the cylinder assembly, serving the following important functions:
1. Forms the Working Surface
- The cylinder liner provides the precise sliding channel needed for the piston’s reciprocating motion.
- It must have high strength and wear resistance to withstand high temperatures, high pressure, and friction with the piston rings.
2. Sealing Function
- Together with the piston rings, the liner helps form a sealed combustion chamber, preventing gas leakage and ensuring combustion efficiency.
- Its sealing capability directly affects the engine's compression ratio and power output.
3. Heat Transfer
- The liner transfers the heat generated during combustion to the cooling system (e.g., water cooling or air cooling), preventing the engine from overheating.
- It requires excellent thermal conductivity to maintain a stable working temperature.
4. Reduces Wear
- The liner protects the engine block, reducing wear caused by direct contact between the piston and the cylinder block.
- When the liner is severely worn, it can be replaced without the need to replace the entire engine block, thereby lowering maintenance costs.
5. Corrosion Resistance
- The inner wall of the liner must resist corrosion from combustion gases, while the outer wall must resist corrosion from the cooling fluid. Therefore, materials are often made of special alloys or treated with surface coatings.
6. Supports Assembly Flexibility
- In some diesel engines, wet or dry cylinder liner designs are used for easy maintenance and replacement:
- Wet cylinder liners: Directly contact the coolant, providing better heat dissipation.
- Dry cylinder liners: Do not contact the coolant directly, resulting in a more compact structure.
The cylinder liner is essential for the reliable operation of a diesel engine over time, and its design and manufacturing quality directly impact the engine’s performance and lifespan.
