Electronic control system of single ECU sub-control throttle valve

Abstract

The invention discloses an electronic control system of a single ECU sub-control throttle valve, and provides an electronic control fuel injection system structure for feeding fuel for a gasoline engine. The electronic control fuel injection system structure for feeding the fuel for the gasoline engine comprises a throttle valve body 3, a fuel injector 5, a steering engine and connecting piece 2 and an angle sensor 4. The throttle valve body is installed on an engine air inlet valve 1, the fuel injector, the steering engine and the angle sensor are installed on the throttle valve body, air enters from an air inlet, the fuel is atomized and injected into the throttle valve body through the fuel injector and mixed in the throttle valve body to enter an engine air inlet channel; the steeringengine controls the starting angle of a valve shaft piece, the amount of air inlet can be controlled, the angle sensor is connected to a valve shaft end, and the starting angle of the valve shaft piece can be detected, and the starting angle of the valve shaft piece is fed back to an ECU; and the ECU adjusts the working state of each throttle valve according to the flight condition of an unmannedaerial vehicle. The electric control fuel injection system has the advantages that the structure is compact, installation and debugging are convenient, the reliability is high, the weight is low, combustion is good, atomization mixing in advance achieves the optimal combustion medium ratio and the like, and the flight control function extension of the unmanned aerial vehicle is relatively convenient.

Description

Technical field [0001] The invention realizes an electronic control system of a single ECU that controls the throttle valve separately. It can be used as a fuel supply device for engines of rotary wing drones, powered parachutes, model airplanes and other equipment, and belongs to the field of power machinery. Background technique [0002] The current medium and heavy-duty multi-rotor UAVs (above 100kg) mostly use gasoline engines as power, and most of the gasoline engine fuel supply systems use old-fashioned carburetor fuel injection systems. The carburetor fuel injection system has difficult to control air intake. The fuel injection quantity and timing cannot be accurately combined with the working state of the engine for proper fuel injection and air intake, and the structure of the carburetor is complex, which is not conducive to weight reduction and maintenance of the UAV. Summary of the invention [0003] An electronically controlled fuel injection system structure for supp...

[0002] Most of the current medium and heavy multi-rotor UAVs (above 100kg) use gasoline engines as power, and most of them use old-fashioned carburetor fuel injection systems in gasoline engine fuel supply systems. The amount of fuel injection and the timing of fuel injection cannot be accurately combined with the working state of the engine for proper fuel injection and air intake, and the structure of the carburetor is complex, which is not conducive to weight loss and maintenance of drones
