Abstract

The invention discloses a high occlusion cylinder liner. The high occlusion cylinder liner comprises a cylinder liner body, wherein the inner surface of the cylinder liner body is coated with an innercoating; the inner coating is 80-120 [mu]m in surface roughness and 0.2-0.4 mm in thickness; an annular groove body is formed in each of the two ends of the outer surface of the cylinder liner body;the annular groove bodies are 0.1-0.4 mm in depth; and burrs, which are 0.1-0.5 mm in height, are arranged in the middle area on the outer surface of the cylinder liner body. The invention further discloses a preparation method of the high occlusion cylinder liner. The high occlusion cylinder liner and the preparation method thereof have the technical effects that the occlusion force is great, andthe service life is long.

Description

technical field [0001] The invention relates to the field of cylinder liner production, in particular to a high-occlusion type cylinder liner and a preparation method thereof. Background technique [0002] Automobile engine is a machine that can convert other forms of energy into mechanical energy. It is the heart of the automobile and affects the power, economy and environmental protection of the automobile. As one of the main accessories of the engine, the cylinder liner is a key component of the A-level engine, and its performance directly affects the technical requirements of the engine's power, reliability, economy, emission, and noise. [0003] At present, the production cost of the traditional cylinder liner is high, the running-in time is long, the bite force is poor, the service life is short, and it is difficult to meet the requirements of the high-performance energy-saving and environmentally friendly engine for the strength, wear resistance and cost of the cylind...
