Abstract

The invention discloses a Cr plating hanger of inner holes of cylinder sleeve, composed of anode, cathode guide rod, anode insulating sleeve, primary guide ring, and clamp ring and screw of cylinder sleeve, where the anode insulating sleeve is set with top power line shield cap, the bottom end of the anode is set with bottom power line shield disc, the anode is set with holes, the outer diameter at the bottom end of the anode is less than that on the top, there is an anode positive sleeve fixed with the cathode outside the top of the anode, there is a gas roundabout cavity formed between the top power line shield cap and the primary guide ring. It has the characters of fixed position of cathode and anode, high plating efficiency, accurate positioning cylinder sleeve, a little deformation, etc.

Description

technical field [0001] The present invention relates to a piston ring for a cylinder of an internal combustion engine, and further refers to an open end structure of the piston ring. Background technique [0002] In the prior art, the piston ring placed in the piston ring groove has always had three air leakage problems, that is, air leakage from the opening end of the ring in the shape of a straight cut, air leakage from the wall gap between the piston ring and the cylinder wall, and air leakage in the piston ring groove. The upper and lower side gaps leak air. These leaks have resulted in insufficient fuel combustion of the engine, reduced output, and shortened engine life. Contents of the invention [0003] The technical problem to be solved by the present invention is to design a piston ring that automatically closes and adjusts the gap in view of the defects in the prior art. Two identical piston rings are stacked and placed in the same ring groove of the piston, whi...
