Integrated electronic injection/ignition system for aviation fuel engine

Abstract

The invention provides an integrated electronic injection/ignition system for an aviation fuel engine. The system structurally comprises a throttle valve assembly, an electric nozzle, a steering engine assembly, an air filter, a spark plug, a DD integrated circuit board and an oil supply system, wherein the throttle valve assembly comprises a throttle valve body, a throttle valve, a throttle valve shaft, a throttle valve return spring and a throttle pull bar, and the steering engine assembly comprises a steering engine, a steering engine rocking arm and a bulb pull bar; and the DD integrated circuit comprises an electronic control unit (ECU) and a capacitor discharge igniter (CDI). According to the invention, a miniaturized piston engine oil injection system is designed, the two major problems of mechanical spindle adjustment and low oil injection precision are avoided, a conventionally independent ignition system and an injection system are also integrated together, the structure is simplified, the space is saved, and redundancy design and self-check design also help to improve the flight safety and the maintenance efficiency.

Description

technical field [0001] The invention belongs to the field of engine design, and in particular relates to an integrated electric injection / ignition system for an aviation fuel engine. Background technique [0002] The history of the piston engine can be traced back to the beginning of the birth of the aircraft. It developed rapidly and was widely used in the first half of the 19th century. It reached its peak during World War II. Almost all fighters, bombers, transport aircraft and reconnaissance aircraft are made of piston aircraft engines plus propellers. power source. After World War II, in order to pursue higher flight speed and altitude, aircraft gradually adopted gas turbine engines, and piston aeroengines lost their dominant position. In recent years, model airplanes and unmanned aerial vehicles have developed rapidly. Since small piston aeroengines are more economical than gas turbine engines, they have been widely used. [0003] The carburetor engine is the most co...
