A micro-oscillating internal combustion engine with a sealed structure

Abstract

The invention provides a miniature oscillating internal combustion engine with a sealed structure. An oil storage groove is formed in an end, which faces the inner wall of a cylinder, of a rotor oscillating arm of the miniature oscillating internal combustion engine; ends, which face the inner wall of the cylinder, of end arms on two sides of the oil storage groove are provided with labyrinth structures; an oil storage groove is formed in an end, which faces a rotor oscillating arm shaft, of a cylinder support; and ends, which face a shaft, of end arms of two sides of the oil storage groove are provided with labyrinth structures, sealing and lubricating effects are achieved, contact area between moving and fixed components is reduced, improvement of stability of the engine is facilitated, the oscillating arm is prevented from being jammed, and power density and energy density of the oscillating arm can be improved further.

Description

technical field [0001] The invention relates to a miniature oscillating internal combustion engine, in particular to a micro oscillating internal combustion engine with a sealing structure. Background technique [0002] The development of micro devices and portable devices is very rapid, and the market demand is strong, but the energy supply system has become the main bottleneck in the development of such devices, and there is an urgent need for energy supply units with small size, light weight and long energy supply time. The micro energy power system based on fuel combustion has obvious advantages in both energy density and power density. Among them, the micro-oscillating internal combustion engine has the advantages of compact structure, easy processing and low cost, and is one of the most promising micro-energy power system solutions. The miniature oscillating internal combustion engine mainly includes components such as a cylinder block, a swing arm, a rotating shaft, ...

AI Technical Summary

Problems solved by technology

[0004] Although reducing the distance between the swing arm and the cylinder can effectively reduce the flow area of ​​the gap, thereby reducing the leakage flow, but this method requires higher processing accuracy, which will greatly increase the processing cost, and the reduction of the gap will also increase Possibility of swing arm jamming, reducing engine stability
