Abstract
PURPOSE: To prevent the interruption of engine operation by feeding a fixed amount of fuel automatically and by actuating the alarm means when the hot-wire type suction air quantity sensor is broken in the electronic fuel injection device.
CONSTITUTION: Outputs of the air temperature sensor 13, cooling water temperature sensor 14, suction air quantity sensor 12 and crank angle sensor 15 are fed to the control unit 10, the injector 11 attached to the throttle chamber 4 is driven and controlled according to the data obtained by processing said outputs to control the fuel injection. When the hot-wire type sensor as a suction air quantity sensor 12 is burned out, the fact is detected to drive the alarm means, the opening extent of throttle valve 5 is informed by opening and closing the throttle valve full closing switch, the quantity of fuel injection can be changed according to the opening and closing states.
