Problems solved by technology

Most of the existing power generation systems adopt the method of separating the prime mover and the generator. This method has many disadvantages, such as large volume, complex structure, low electromagnetic conversion efficiency, and large energy consumption.
[0003] Among the various miniature free-piston generator technologies currently disclosed, such as patent application No. CN201310199467.9 and patent application No. CN20142007671.6, the intake air of the generator is preheated to increase the initial temperature of the mixture, thereby improving the generator efficiency, but did not consider the means of pressurizing the initial intake air or combining pressurization with preheating, etc., there is a large end-of-expansion velocity of the micro-free piston generator that cannot be fully utilized, thereby forming a waste of energy

Abstract

The invention provides an HCCI micro free piston electric generator. The HCCI micro free piston electric generator comprises a stator and micro free piston power devices. The stator is provided with amain air inlet, the stator is divided into stator work units through the main air inlet, the stator work units are symmetrically distributed and are of the same structure, fixed dividing rings are arranged in the stator work units, the micro free piston power devices are arranged in the stator work units, a work chamber comprises a combustion chamber and a pressure chamber, the pressure chamber is communicated with the main air inlet, a combustion chamber air inlet and a combustion chamber exhaust opening are formed in the combustion chamber, a pressure chamber air inlet is formed in the pressure chamber, the pressure chamber air inlet and the combustion chamber air inlet are connected through a pipeline, a one-way valve is arranged on the main air inlet, and an exciting winding and a stator winding are arranged on the inner wall of each stator work unit. Mechanical energy is directly converted into electric energy, waste gas waste heat is used for preheating mixed gas, the initial temperature of the mixed gas is improved, and compression combustion of the mixed gas is facilitated.

Description

technical field [0001] The invention relates to a micro power system related to the field of internal combustion engines and the field of power generation, in particular to an HCCI micro free piston generator. Background technique [0002] As a new type of power device, micro electromechanical power system is widely used in various fields of people's life, and has a good development prospect. Compared with general power sources, such as lithium batteries, power devices using hydrocarbon fuels have the advantages of low energy density, low emissions, and low pollution, which makes the miniaturization and portability of equipment possible. The mechanical structure of the micro-free piston power unit does not have the crank connecting rod, gas valve and other mechanisms of the traditional internal combustion engine. The free piston moves in a straight line in the cylinder without being constrained by mechanical force, but there is a large heat transfer loss caused by a relative...
