PURPOSE:To rationally save fuel, by exciting a solenoid valve in a carburetor and shutting off a feed of fuel at deceleration and sharp downhill running of a vehicle. CONSTITUTION:At flatland running, a mercury switch S1 is in a condition connected with contacts A-B while a mercury switch S2 in a condition connected with contacts A1-B1. under this condition, terminal voltage EG of a DC generator 11, operated interlocking to running speed of a vehicle, is applied to a capacitor C, and the voltage becomes EG EC when the vehicle is at constant speed running. Now if the vehicle is decelerated, the voltage becomes EG<EC, and the capacitor C is discharged, then its discharge voltage is amplified by an amplifier 12 and fed to an AND circuit 13. Further at this time, if EG>E1 (compared voltage), its deviation is amplified by an amplifier 14, and the amplified voltage EB is applied to an AND circuit 13, then output is generated to electrically conduct a solenoid valve 15. At sharp downhill running, the mercury switch S1 is switched to contacts C-D, and the solenoid valve 15 is similarly conducted. |
