The main function of bimetallic cylinder liners is to improve the performance and durability of engines and other machinery.

Firstly, bimetallic cylinder liners have excellent wear resistance and corrosion resistance, which can significantly extend the service life of engines and other machinery. This is mainly due to the use of a combination of two different metals or alloys in the bimetallic cylinder liner, one of which is a metal with high elastic modulus and high strength, such as copper alloy or titanium alloy, and the other is a metal with good wear resistance, such as ferritic stainless steel. This combination enables the bimetallic cylinder liner to maintain its structural integrity and performance stability even under high pressure and high temperature.

Secondly, bimetallic cylinder liners can improve the noise reduction performance of the engine. Its double-layer structure can effectively isolate the vibration and noise of the engine, reduce noise, and improve driving comfort.

In addition, the bimetallic cylinder liner also has the characteristic of low thermal expansion coefficient, which helps to reduce the friction loss between the cylinder liner and the piston, and improve the power output efficiency of the engine. This design also helps reduce the weight of the engine, lower fuel consumption, and improve fuel economy.

In specific industrial fields such as automotive and engine manufacturing, bimetallic cylinder liners are widely used. In automotive engines, it can serve as an inner lining material for the cylinder block, improving its wear resistance and corrosion resistance. At the same time, bimetallic cylinder liners are also suitable for the inner wall materials of hydraulic cylinders and screw compressors, which can effectively prevent wear and corrosion of the inner wall surface and improve the service life of equipment.

Overall, bimetallic cylinder liners play an important role in improving engine performance, extending mechanical service life, reducing noise and fuel consumption, and are indispensable components in modern industrial fields.
