Ceramic liners
How to choose ceramic cylinder liner
As known,a good ceramic cylinder liner is very important for the whole engine, what should we pay attention to when we buy it?
 
1, When buying new parts: to check the standard cylinder liner and piston size grouping code, installed cylinder liner and piston must make the standard piston size grouping code and standard cylinder liner size grouping code the same, only in this way to ensure that there is a standard fit gap.Multi-cylinder diesel engines, each cylinder must be installed with the same grouping code cylinder liner and piston.
 
2, Should pay attention to the inspection of the cylinder plug gap before loading, sometimes the size of the cylinder liner and piston grouping code is the same, in order to ensure the assembly standard, before loading should also be a test, in order to prevent fake and inferior products to cheat.Multi-cylinder high-speed diesel engine, but also pay attention to the weight of the cylinder piston group should be within the prescribed range.

Bimetal Liners
The b-metal liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, it adapts the technology of centrigugal forging;  the inner sleeve is high chromium iron with wear&corrosion resistance, after heat treatment, the hardness of it can reach to a lever of 62 RC.
The bimetal liners produced by us strictly control the tolerance, assure the easy installation, inner sleeve is highly polished with abrasion&corrosive resistance, can used in various bad working environment with longer service life. 
Liner Outer Sleeve: 45#forged steel, tensile strength is σb>610MPa, yield strength is σs>450MPa, ,elongation hardness is §>17%,hardness is HRC180-200
Liner Inner Sleeve: high chromium cast iron (centrifugal forged). Annealing hardness is HRC≤40. Quenching hardness is HRC59-67
Chemical Composition:C 2.8%-3.1%  Cr 26%-28%  Si 0.6%-0.9%  Mn 0.5%-1% Mo 0.5%-0.8% S , P <0.05%;
