Abstract

The invention relates to a small and medium-size triangular rotor engine double oil injection system, in particular to a small and medium-size kerosene triangular rotor engine double-oil-injector injecting method, and belongs to the field of triangular rotor engines. The system simultaneously adopts two oil injectors to inject kerosene, the kerosene required in the combustion process is mainly supplied by a first oil injector, and a second oil injector injects a small amount of fuel oil and achieves an igniting effect. The injecting time and oil injecting amount of each oil injector can be precisely controlled, spot dividing injection and time sharing injection are achieved, the good atomization effect is achieved while the large power-mass ratio of a rotor engine is kept, reliable igniting is achieved, the problems that a kerosene rotor engine is poor in atomization, low in combustion efficiency and high in emission are solved, and the performance of the small and medium-size triangular rotor engine is improved.

Description

technical field [0001] The invention relates to a fuel supply system for a small and medium-sized triangular rotor engine, in particular to a method for injecting double fuel injectors of a small and medium sized kerosene triangular rotor engine, and belongs to the field of triangular rotor engines. Background technique [0002] The triangular rotor engine is a kind of internal combustion engine, which has a special geometric structure and movement mode. Compared with the traditional reciprocating piston engine, it has the advantages of simple structure, small size, light weight, good high-speed performance, low noise, low vibration, and high power-to-weight ratio, and has been widely used in many fields, especially in the military field. Due to its high power-to-weight ratio, small size, light weight, and low noise, it can increase the load when used in the field of drones and loitering bombs, and can reduce the overall mass and volume, enhance concealment, and is beneficia...
