The shape of cylinder sleeve is a cylindrical, placed in the cylinder block hole, and fixed by the cylinder head.
By cooling water provided outside the piston makes reciprocating motion in its inner hole,
Below are the role it plays:
1. Combined with cylinder head ,piston formed cylinder working space.
2. It bear side thrust caused by cylindrical shape piston,becomes the guide of reciprocating of piston movement.
3. Chieve appropriate operating temperature by transfter other parts heat to cooling water.
4. There're air port of the two stroke diesel engine, which is opened and closed by the piston to
realize the air distribution.
