Embodiment Construction

[0034] An integrated EFI / ignition system solution for aviation fuel engines, such as figure 1 As shown, its composition includes throttle body 1, throttle valve 2, throttle shaft 3, throttle return spring 4, throttle lever 5, electric nozzle 6, steering gear 7, steering gear rocker arm 8, ball head rod 9, Air filter 10, spark plug 11, ECU 12, igniter 13 and oil supply system 14.

[0035] The design of the integrated EFI / ignition system for aviation fuel engines is mainly divided into two parts: (1) The design of the actuator, including the design of the throttle assembly, the design of the fuel supply system, the selection and installation of the steering gear, and the selection and installation of the spark plug . (2) Integrated circuit board design, including ECU electronic control unit design and capacitor discharge igniter design.

[0036] The throttle assembly is mainly composed of a throttle body 1, a throttle valve 2, a throttle shaft 3, a throttle return spring 4 and...

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...
