The novel cylinder liner comprises a square alloy casing, the upper part of the square alloy casing is provided with a circular shock-absorbing rubber pad, and the circular shock-absorbing rubber pad and the square casing are bonded by super glue.
When the engine is overhauled, if there is no special tool for installing the cylinder liner, it is usually installed by placing a wooden block on the cylinder liner and hammering it down with a hammer, so that the operation may sometimes damage the cylinder liner due to uneven force.
In the new type of cylinder liner, a set of coaxial two cylinders is added at the rear end of the cylinder body, so that the central column runs through the two cylinders, the first cylinder and the cylinder at the same time. in the barrel.
Cast-in cylinder liner, mainly used in automobile engines, is characterized in that: an irregular burr-like structure is arranged on the outer surface of the cylinder liner formed by machining. It eliminates the metallurgical metallographic, dimensional and and other defects.
The high-strength cylinder liner breaks through the structural form of the traditional engine cylinder liner. Multiple closed annular supporting fins cooperate with the reinforcing connecting pieces to firstly act as a stirrup along the circumferential direction of the radiating wall layer, and strengthen the radiating wall layer. Avoid deformation of the heat dissipation wall layer.
