Heavy oil rotor engine auxiliary ignition device based on hydrogen flame ignition

Abstract

The invention provides a heavy oil rotor engine auxiliary ignition device based on hydrogen flame ignition. The heavy oil rotor engine auxiliary ignition device based on hydrogen flame ignition comprises a heavy oil rotor engine and a hydrogen auxiliary ignition device body. The heavy oil rotor engine comprises a cylinder body, a combustion chamber, a heavy oil nozzle and a triangular rotor. The hydrogen auxiliary ignition device comprises a first cavity, a second cavity, an inclined ignition channel, a hydrogen nozzle, a specially-made spark plug, a first sealing piece, a second sealing piece, a first fixing plate, a second fixing plate and a third fixing plate. According to the novel auxiliary ignition device based on hydrogen flame ignition designed by the invention, a stable hydrogen flame ignition source can be formed in the first cavity and the second cavity, and combustible mixed gas is continuously ignited through the inclined ignition channel. The device can fully utilize thecharacteristics that hydrogen is easy to diffuse, high in combustion rate, wide in flammability limit and the like to improve the stability and the reliability of the ignition and combustion process of the engine. The heavy oil rotor engine auxiliary ignition device based on hydrogen flame ignition also has the characteristics of simple structure, convenience in disassembly and assembly, easinessin implementation and low cost.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to an auxiliary ignition device for heavy oil rotary engines based on hydrogen flame ignition. Background technique [0002] The heavy oil rotary engine is a rotary internal combustion engine, which has the outstanding characteristics of compact structure and high power-to-weight ratio, and it has recently received attention. However, the heavy oil rotary engine faces the problem of low combustion efficiency and needs to be solved urgently. This is because during the working process, from the compression stage to the top dead center, the shape of the combustion chamber is narrow and long, and the airflow in the cylinder is a high-speed forward one-way flow. In this high-speed and one-way airflow environment In this case, the flame is prone to quenching during the combustion process, which leads to poor combustion stability of the heavy oil rotary engine. In addition, due...
