Abstract

A cylinder sleeve inner wall oil circuit structure comprises helical lines and micro-pits. Each helical line is 1-150 micrometers in depth, 1-100 micrometers in width, 10-100 in thread number and 1-20 micrometers in pitch. Each micro-pit is 3-100 micrometers in depth. A production method of the cylinder sleeve inner wall oil circuit structure includes: laser transmitted by a laser device passes through optical fibers to form laser beams, the laser beams are projected to a reflector and reflected to a cylinder sleeve inner wall through the reflector for itching the micro-pits and the helical lines. Spot and linear lubricant oil way structures in regular distribution are disposed on the surface of the cylinder sleeve inner wall. Wear resistance is doubled or tripled compared with the prior art, fuel consumption is reduced by 20-25%, cylinder abrasion is reduced from 5 micrometers to 2.5 micrometers, emission of hydrocarbon particles is reduced by 20-25%, and the service life of the cylinder sleeve is prolonged by 1.4 folds.

Description

technical field [0001] The invention relates to a cylinder liner, in particular to an oil passage structure on the inner wall of the cylinder liner. The invention also relates to a preparation method of the cylinder liner oil passage. Background technique [0002] The inner wall of the cylinder liner is the guiding surface for the reciprocating motion of the piston. During operation, the friction pair of the cylinder liner and the piston is under high temperature, high pressure, and working conditions with particles and corrosive media. Transitional wear will cause oil leakage, steam leakage and power loss. Decrease, which requires good lubrication on the inner wall of the cylinder liner. On the basis of using lubricating oil, it is also necessary to reasonably prepare an oil storage structure on the inner wall surface of the cylinder liner. The oil storage structure is mainly composed of micro-dotted lines. [0003] The traditional processing technology of the inner wall o...
