Curved surface rolling bearing type piston for internal combustion engine

Abstract

The invention discloses a combustion engine camber drum shaft gas piston for improving the power mechanical efficiency, which is composed of piston skirt, packing ring and piston pin hole wall, wherein there is a open on the lateral surface of the piston skirt; the camber antifriction bearing is installed in the piston skirt; the camber antifriction bearing is fixed on the inner wall of the gas piston; The invention reduces the mechanical frictional loss and wasted power, which improves the power mechanical efficiency.

Description

technical field [0001] The invention relates to a piston of an internal combustion engine, in particular to a curved surface rolling bearing type piston of an internal combustion engine capable of improving power mechanical efficiency. Background technique [0002] As we all know, there is friction between the piston skirt of the traditional internal combustion engine and the inner wall of the cylinder, which causes a serious loss of mechanical efficiency. In 2000, the book "Internal Combustion Engine Performance Improvement Technology" published by People's Communications Publishing House introduced that 8% of the loss of the entire engine is caused by mechanical Caused by friction, while the gasoline internal combustion engine piston assembly accounts for about 44% of the entire mechanical friction loss. This loss accounts for about 4% of the total output power. Among them, the friction loss of the piston skirt accounts for 90% of the friction loss of the piston assembly,...
