What are the characteristics of a good quality? How to judge the quality of cylinder liner?

We all know that cylinder liner is a very important part of diesel engine. Good quality cylinder liner will be more wear-resistant, long service life, and not easy to produce noise. Poor quality cylinder liner is not durable, and may have problems soon after replacement. There may also be noise or oil channeling due to imprecision and large fit clearance. There may also be insufficient cylinder pressure due to poor sealing, which will affect the power Fuel consumption and other aspects of performance. In terms of structure, there are several types of cylinder liners as follows:

So how to judge the quality of cylinder liner? How to choose a good quality cylinder liner?

Good quality cylinder liners have fine workmanship and sufficient materials, while ordinary quality cylinder liners look rough. If you want to directly distinguish the true from the false by naked eyes, it's really difficult. You can try these methods:

1. Whether the external packaging is simple or well packed?(good quality cylinder liner should have proper protection, moisture resistance, manufacturer name, address, contact number, etc.). Generally, good manufacturers will not use inferior materials and turn out substandard goods.

2. Open the package to see if there is anti rust package on the outside of the cylinder liner (otherwise it is easy to rust).

3. Check the package directly to see if there is burr, sharp edge or rust on the outside surface of the cylinder liner.

4. Check whether the angle of the inner surface of the cylinder liner hole is the same as that of the original parts (this pattern is honed by a special honing machine, Fake products may have inconsistent angles).
