Scavenging system of constant-pressure air source type free piston internal combustion generator

Abstract

The invention relates to a scavenging system of a constant-pressure air source type free piston internal combustion generator, and belongs to the technical field of power machinery. The scavenging system comprises a scavenging box, an air cylinder and a constant-pressure air source, wherein the air cylinder comprises an air cylinder sleeve, a cylinder body and an air cylinder cover; the air cylinder sleeve is fixedly connected with the cylinder body; one end of the cylinder body is tightly and fixedly connected with the air cylinder cover, and the other end of the cylinder body is fixedly connected with the scavenging box; a sealing material such as a pad is clamped between contact faces at two ends, so that a sealing effect is achieved; a first main scavenging port, a second main scavenging port and an auxiliary scavenging port of the scavenging box are correspondingly connected with a first main scavenging port, a second main scavenging port and an auxiliary scavenging port formed in the air cylinder sleeve respectively through a first main scavenging pipeline, a second main scavenging pipeline and an auxiliary scavenging pipeline of the cylinder body; an air blower of the constant-pressure air source is connected with an air inlet of an air storage tank; and an air outlet is connected with an air inlet of the scavenging box. When the constant-pressure air source is used, the air inlet pressure intensity is higher than that of external atmosphere pressure; a pressurization effect is achieved; and the scavenging system adopts special design, so that the scavenging efficiency is obviously improved.

Description

technical field [0001] The invention relates to a constant pressure air source type free piston internal combustion generator scavenging system, which belongs to the technical field of power machinery. Background technique [0002] Energy and environmental issues are one of the keys restricting the sustainable development of society. In order to achieve the goal of creating an energy-saving and environment-friendly society, people regard green, energy saving, environmental protection and high efficiency as the theme of the times, and have been improving and inventing various power mechanical devices for energy conversion, among which the free piston internal combustion generator is kind of. It directly connects the free piston with the linear motor mover to form the only moving part - the piston assembly. When the system is running, the gas in the cylinder burns and expands to do work, pushes the piston and drives the mover to move, and then generates electrical energy, an...
