What Is A Liner In Automobiles? - SKengineers

WHAT IS A CYLINDER LINER? It is a cylinder that is fitted to the engine block to form the cylinder, and is one critical function part that forms the engine interior. In Japan they are usually called Cylinder Liners, but some countries (companies) call them Cylinder Sleeves. 3 functions of Cylinder Liners - Function 1 Form the sliding surface - Reciprocating movement/Liner/Cooling water/Sliding surface Tightly holds when the valve is seated, prevents compressed gas or combustion gas leaking into the manifold from between the valve and Valve Seat. High burn resistance Low self-friction Low friction with the piston ring Low lubricating oil consumption Function 2 Heat conduction - Combustion heat/Liner/Cooling water Reduces vale and cylinder head friction at the same time. Function 3 Keep airtightness - Explosion/Stop the gas/Gas leaks Prevent compressed gas and combustion gas leaking out. The liner should not be prone to deformation due to the high pres...
