Abstract

PURPOSE:To eliminate useless consumption of fuel and improve fuel consumption, by such constitution that when an accelerator pedal is completely released from its depression at running operation, supply of fuel is automatically cut off before deceleration to preset minimum speed. CONSTITUTION:There are provided a speedometer switch 4, for instance, to be turned ON at not higher than 25km/h while OFF at not lower than 25km/h and an accelerator pedal switch 5 to be turned ON by depression of the pedal while OFF by releases of its depression. Further a clutch pedal switch 6 is provided to be turned ON for disengagement of a clutch while OFF for its engagement, and a transmission switch 7 is provided to be turned ON in a neutral position of the gear while OFF except the neutral position. When the above switches 4-7 are all turned OFF, a control device 9 of gasoline jet, for instance, in a float chamber is operated to a stop state through a collective socket 8, and supply of fuel is stopped to an engine 1.
