A six-cylinder opposed free-piston internal combustion generator

Abstract

The present invention proposes a six-cylinder opposed free-piston internal-combustion generator, which includes two free-piston internal-combustion units, a set of opposed-piston internal-combustion units and two linear generator sets. The low-pressure cylinder group in the group and the opposed-piston internal combustion unit performs the first-stage compression, and then performs the second-stage compression in the high-pressure cylinder group. The combustion medium first undergoes the first-stage expansion in the high-pressure cylinder group, and then in The second stage of expansion takes place in the low-pressure cylinder bank. Solved the technical problem of how to improve the power generation efficiency of the opposed free-piston generator and the reliability of the device, and proposed a six-cylinder opposed free-piston internal combustion generator, using the back-mounted free-piston generator instead of the opposed free-piston generator The recovery device in the device improves the reliability and power generation efficiency of the device.

Description

technical field [0001] The invention relates to a six-cylinder opposed free-piston internal combustion generator, which belongs to the technical field of power devices. Background technique [0002] With the continuous development of society, people's demand for energy is increasing day by day, and the energy problem has become the main problem restricting the further development of all walks of life. Among various forms of energy, electric energy is one of the most widely used energy sources, and electric energy is mainly provided by diesel engines in industries such as vehicles and ships. [0003] In the traditional diesel engine power generation process, the form of energy transmission is firstly converted from the chemical energy of the fuel through the combustion of the diesel engine into the mechanical energy output by the crankshaft, and then this part of the mechanical energy drives the motor to generate electricity and converts it into electrical energy. The entire...

AI Technical Summary

Problems solved by technology

The entire energy conversion process has gone through many steps, and at the same time, a large part of the complex mechanical structure of the diesel engine is lost, so the overall power generation efficiency is low

[0004] The free piston generator couples the working characteristics of the free piston generator and the linear motor, and can directly convert the chemical energy of the fuel into the form of electrical energy. Compared with the traditional internal combustion engine power generation process, it has higher power generation efficiency and economic performance, but currently The back-mounted free-piston generator needs two pairs of cylinders to drive a group of generator excitation coils, and the power density is small

Although the power density of the opposed free piston generator is high, the recovery device reduces the reliability of the device and increases the failure rate of the internal combustion generator, so it is difficult to popularize
