What Is The Difference Between A Cast Iron Liner Engine And A Coated Engine Without A Liner?

2022-03-31


1. The heat dissipation capacity is different; the coating cylinder block has good heat dissipation, and the material is low alloy steel, which is sprayed to the inner wall of the aluminum alloy cylinder hole by plasma spraying or other spraying processes. Suitable for high-strengthened and high-heat-load engines;

2. The lubricating ability is different; the surface morphology and performance of the coated cylinder block are different from those of cast iron, and the performance of the cylinder block can be changed by changing the coating material;

3. The design of the cylinder block is different; the cylinder center distance of the engine with a cylinder liner cannot be designed to be small, because it is limited by the thickness of the cylinder liner;

4. The cost is different; the coating cylinder is more expensive and the process is complicated;
