The Cylinder Liner is a cylindrical part that is placed in the cylinder block hole of the body and is secured by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water outside.
The functions of the cylinder liner are:
1. Together with the cylinder head and piston, it forms the cylinder working space.
2. The cylinder liner of the cylinder piston diesel engine is the lead of the reciprocating movement of the piston, which is subjected to the side thrust of the piston.
3. The heat of the piston assembly and itself is transferred to the cooling water to make the working temperature appropriate.
4. The cylinder liner of a two-stroke diesel engine is arranged with an air port, which is opened and closed by a piston to realize gas distribution.
