Many customers are still unclear about the function of diesel engine cylinder liner, so I will explain it to you today. First of all, it is necessary to understand the working principle of the cylinder. The cylinder is a cylindrical space used to guide the piston to move back and forth. It forms a common combustion chamber with the cylinder head and the piston. When working, it is easy to cause high temperature, high pressure gas and the non-stop operation of the piston. Wear on cylinder surfaces. After the wear reaches a certain level, it is easy to leak a large amount of gas into the crankcase, which will deteriorate the performance of the diesel engine and deteriorate the oil.

Therefore, the main functions of the cylinder liner are obvious, mainly including:

1. Improve the strength and wear resistance of the cylinder;

2. It is easy to maintain and reduce maintenance costs. The first thing the cylinder wears during the work is the cylinder liner. It only needs to be repaired or replaced with the cylinder liner.

3. The cylinder liner of the two-stroke diesel engine is equipped with air ports, which are opened and closed by the piston to realize gas distribution.

Commonly used diesel engine cylinder liners are made of better wear-resistant alloy cast iron, such as high phosphorus cast iron, boron-containing cast iron, ductile iron, austenitic cast iron, etc. In order to make the wear resistance of the cylinder liner better, molybdenum or carbonization treatment can also be sprayed on the surface.
