Internal combustion-linear generating integrated power system

Abstract

The invention discloses an integrated power system of internal combustion-linear power generation. The power system comprises a combustion chamber of an internal combustion engine with four strokes, which comprises a cylinder, a piston arranged inside the cylinder as well as an ignition device and a valve mechanism arranged on the cylinder. A linear motor with work modes of power generation and electro-motion comprises a linear motor rotor and a linear motor stator; wherein, the linear motor rotor is provided with a detecting component of piston movement positions and is connected with a piston inside the combustion chamber of the internal combustion engine with four strokes; the linear motor stator is connected with a reversible storage device of electricity through an electronic controlling unit connected with the ignition device, the valve mechanism, the electronic controlling unit, the reversible storage device of electricity and the detecting device of piston movement position respectively. The invention has high specific power and can realize the traveling of low compression ratio and high expansion ratio of the internal combustion engine and guarantee the separate working modes of traveling in different cylinders and groups with high load rate so as to improver the system efficiency.

Description

a technical field [0001] The invention belongs to an integrated power system that outputs electric energy after energy conversion and transmission after inputting fuel, and can be applied to automobile power and other occasions that require mobile power sources and portable power sources, especially an internal combustion-linear power generation integrated power system . Two background technology [0002] The free-piston engine has a long research history. In the 1950s, there was research on combining it with a single-stage turbine as a gas generator. A technical scheme of a typical two-cylinder opposed two-stroke linear generator is shown in figure 1 (Ehab F. Shoukry. Numerical Simulation for Parametric Study of a Two-Stroke Compression Ignition Direct Injection Linear engine. Doctoral Dissertation, West Virginia University, 2003). [0003] This type of free-piston linear generator currently studied mainly applies the working principle of a two-stroke internal combustion ...

[0005] In the domestic utility model patent "Linear internal combustion type power generation device (200420097646.8)" and the invention patent "Internal combustion type mechanical and electric dual energy output method and its device (200410036181.x)", the device still retains the crank connecting rod mechanism of the engine , only a linear power generation part (called "engine internal shunt" in the patent) is added between the piston and the crank connecting rod mechanism. The piston movement is the same as that of a conventional engine and cannot be freely controlled
