Description

Technical Field

[0002] The engine block is one of the basic components of the engine. It is a structure made of cast iron or aluminum alloy, which contains multiple cylinders. Usually, the piston pin seat hole, connecting rod bearing hole, cylinder bore (i.e. cylinder surface) and oil cooling passages are cast in the cylinder block. The cylinder liner, also known as the cylinder liner, is a metal kit built into the cylinder bore of the cylinder block, and the liner is under the piston. One of its main functions is to protect the inside of the cylinder block from piston wear, and it also serves as a seal and cooling function. When the engine is running, the piston moves up and down in the cylinder and comes into contact with the cylinder liner; over time, the cylinder liner may need to be replaced due to wear or excessive wear to maintain engine performance.

[0003] When removing and replacing the existing cylinder liner, a hammer and special tools (such as a socket or a wrench) are generally used to carefully knock along the diameter direction of the cylinder liner, and the cylinder liner is usually pushed out along the shape of the cylinder barrel. The existing removal tools are numerous and complex, and the cylinder body is easily damaged during removal, and generally requires professional operation. Utility Model Content
