Product Parameter

The Role of the Engine Cylinder Liner

An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy.

The cylinder liner is a cylindrical part, which is placed in the cylinder block hole of the body, and is pressed and fixed by the cylinder head. The piston reciprocates in its inner hole, and is cooled by cooling water outside. Together with the cylinder head and the piston, it forms the working space of the cylinder. Its function is as follows:

1. Together with the cylinder head and the piston, it forms the working space of the cylinder.

2. The cylinder liner of the barrel piston diesel engine bears the thrust of the piston side, which becomes the lead of the reciprocating motion of the piston.

3. Transfer the heat of the piston assembly and itself to the cooling water, so that the working temperature is appropriate.

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

Product Application

Cummins engines are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
