Integrated testing and control system of internal combustion type free piston linear power generator with piston travel-controllable effect

Abstract

The invention relates to an integrated testing and control system of an internal combustion type free piston linear power generator with piston travel-controllable effect, and belongs to the field ofenergy power machinery. The integrated testing and control system is characterized in that a single piston, a free piston air cylinder with double functions, and a permanent magnet type linear power generator are coupled; the piston is pushed to do reciprocating movement by the energy released by combustion of combustible mixed gas at the left side of an air cylinder, and the high-pressure mixed gas inputted at the right side of the air cylinder, a rotor of the linear power generator is driven to repeatedly cut magnetic induction lines, and then the energy carried by the combustible mixed gasis converted into electric energy to be outputted; under different running working conditions, the air intake time t at the side A of the air cylinder, and the special displacement points A1 and B1 and preset combustion ratio displacement point X at both ends can be freely changed by a collection control system, so as to change the air intake amount, piston travel and compression ratio of the device, thereby meeting the requirements under different working conditions.

Description

technical field [0001] The invention relates to an integrated measurement and control system for an internal combustion free piston linear generator with a controllable piston stroke, belonging to the field of energy power machinery. Background technique [0002] Energy and environmental issues are the key to restricting the sustainable development of society. With the aggravation of air pollutants and the depletion of fossil energy, improving the efficiency of energy utilization has become an unavoidable and important topic in the field of energy and power. In order to achieve the goal of creating an energy-saving and environment-friendly society, my country takes green, energy-saving, environmental protection and high efficiency as the theme of the times, and has been improving and inventing various power mechanical devices for energy conversion, internal combustion free piston linear generators is one of them. Internal combustion free-piston linear generator is a new type...

Problems solved by technology

However, there is no relatively mature method to realize the precise control of the top and bottom dead centers of the free-piston linear generator. However, the top and bottom dead centers directly determine the compression ratio of the engine, and the compression ratio is a very critical parameter of the engine. It seriously affects the performance parameters of the engine, so the control of the upper and lower dead center positions directly affects the working performance of the entire free piston linear generator
