Abstract
PURPOSE: To control the air-fuel-ratio exactly by supplying additional fuel from an actuator, whose amount follows the fuel increase or decrease demand.
CONSTITUTION: A pressure sensor 43 is provided to detect the pressure fluctuation in the secondary chamber 40 of a vaporizer 8, which converts the pressure fluctuation in the secondary chamber 40 into an electric signal 13 to put out to a comparator 15. The signal is synchronizied at the operation timing ON, OFF of the actuator 7, which tells the amount of fuel supplied for a carbureter 1 directly and that of suction air. An interval between each operation timing becomes short and fuel supply added per hour rises with increase of suction air so that the amount of fuel follows the increase or decrease demand exactly.
