Advantages of engine block with cylinder liner

1. It can reduce the processing of the cylinder block, improve the yield, and use the cylinder liner to improve and ensure the accuracy;
2. The cylinder wall can be processed (boring cylinder) under certain conditions of wear, cylinder pulling, rust, etc., so as to prolong and improve the working life;

3. Optimum material, can select and optimize cylinder liner material for harsh working conditions to achieve excellent working performance.
The cylinder liner is divided into two categories: dry cylinder liner and wet cylinder liner. The cylinder liner whose back does not contact the cooling water is called the dry cylinder liner, and the cylinder liner whose back is in contact with the cooling water is the wet cylinder liner. The thickness of the dry cylinder liner is thin, the structure is simple, and the processing is convenient. The wet cylinder liner is in direct contact with the cooling water, so it is beneficial to the cooling of the engine and to the miniaturization and weight reduction of the engine.
