Abstract
PURPOSE: To enable to selectively use the actuator on the primary side also for the secondary side by a method wherein the fuel passage of the primary side carburetor and the fuel passage of the secondary side carburetor are respectively provided with an auxiliary air bleed passage and the passage combining these is provided with a switching valve.
CONSTITUTION: The primary side carburetor slow air bleed passage 22 and the secondary side carburetor main air bleed passage 23 are collectively provided and the connection port 24a with the air of the collective passage 24 is provided with the first actuator 25, while the collective part 24b is provided with a switching valve 26. According to the output of the air-fuel ratio control circuit 32 the air bleed quantity is controlled, while it is so formed that the collective passage 24 is connected to the secondary side carburetor air bleed passage 23, when the engine load is above the fixed value. Thereby the actuator with a small amount of air-fuel ratio can effectively function so that the simplified construction and the lowered cost can be worked for.
