Electronic control system unmanned aerial vehicle gasoline engine having single ECU sub-control throttle

The invention discloses an electronic control system unmanned aerial vehicle gasoline engine having a single ECU sub-control throttle. The engine includes a basic engine 1, a starting system 2, an engine pedestal 3, an air intake and exhaust system 4, a fuel injector 5, a single ECU sub-control throttle electronic control system 6, an air filter 7 and an air inlet valve 8. The engine is a two-cylinder two-stroke electronically controlled gasoline engine; the single ECU sub-control throttle electronic control system includes a throttle body, the fuel injector, a steering engine, a connecting piece and an angle sensor; a single ECU can separately control the intake opening degree and fuel injection of each throttle, and the ECU can adjust the state of each throttle according to unmanned aerial vehicle flight status, so that precise fuel injection quantity, intake air quantity and injection timing can be achieved; and the angle sensor feeds signals back to the ECU, so that accuracy and stability of flight can be
