A Double Fuel Injection System for Medium and Small Kerosene Triangular Rotary Engines

Abstract

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. The system uses two injectors to inject kerosene at different positions at the same time. The kerosene required for the combustion process is mainly provided by the first injector, and the second injector injects a small amount of fuel to achieve the effect of ignition. It can precisely control the injection time and fuel injection volume of each injector, realize split point and time split injection, achieve better atomization effect while maintaining a large power-to-mass ratio of the rotary engine, realize reliable ignition, and solve the problem of kerosene rotor The problem of poor engine atomization, low combustion efficiency, and high emissions can improve the performance of small and medium-sized kerosene rotary engines.

Description

technical field [0001] The invention relates to a fuel supply system for a small and medium-sized triangular rotary engine, in particular to a dual fuel injector injection method for a small and medium-sized kerosene triangular rotary engine, and belongs to the field of triangular rotary engines. Background technique [0002] A triangular rotary engine is a type of internal combustion engine with a special geometry and movement. 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. It 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 be used in the field of unmanned aerial vehicles and cruise missiles to increase the load, reduce the overall mass and volume, and enhance concealment, which is beneficial to milita...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a small and medium-sized kerosene rotor in order to solve the problems that the weight and volume of the single injector of the existing small and medium-sized kerosene triangular rotor engines are too large, the atomization is not good, the combustion efficiency is low, and the use requirements cannot be met. Engine dual fuel injection system; this system uses two injectors to inject kerosene at different positions at the same time, the kerosene required for the combustion process is mainly provided by the first injector, and the second injector injects a small amount of fuel to play a role in ignition.
