PURPOSE:To prevent the engine stopping at the time of releasing a fuel cut by possessing a fuel cut mechanism cutting the fuel-supply when decelerating an engine and a fuel supply mechanism supplying a required quantity of fuel to the engine when releasing the fuel cut. CONSTITUTION:When a car is decelerated, since all of an engine speed sensor 12, a neutral switch 13, a clutch switch 14, and an idle switch 15 come in OFF- state, a fuel cut signal (a) is given from a control unit 11, and the fuel cut valve 6 is fully closed. In this condition, when any one of the above mentioned detecting devices 12-15 comes in ON-state, a fuel cut-releasing signal (b) is given from the control unit 11. Thus, the electromagnetic pump 25 is driven only for a fixed time through the pump-driving circuit 26 of a fuel-supplying mechanism 16, a fixed quantity of fuel is supplied to a carbureter 3, a throttle valve 2 is simultaneously opened only by a specific angle, and the engine is smoothly operated. |
