Abstract

PURPOSE: To supply fuel suitable for load by making an air-fuel ratio correction by controlling the feedback of air bleed on the basis of the signal of exhaust components as well as by controlling the supply of fuel by air flow rate in carburetor.
CONSTITUTION: The air inlet pipe 3 whose one end is provided with the filter 1 and the other end is connected to the engine 2 is provided with the conical air flow meter 4 in its inside, and the lower end of the meter 4 is connected to the needle 9 moving vertically inside the chamber 7. Fuel is sucked out of the nozzle 10 provided at the top of the chamber 7 through the float chamber 6 and the chamber 7, mixed with air measured by the meter 4, and then supplied through the throttle valve 8 into the engine 2. Also, the lower part of the nozzle 10 is provided with the negative pressure controlling chamber 18 connected to the air bleed 13' and also the electromagnetic valve 12' at the tip of the bleed 13' is drived by the controller 16 receiving the signal of the O2 sensor 15.
