Abstract

PURPOSE: To appropriately control air-fuel ratio at idling by controlling a rate of by-pass air of a carburator by a number of rotation, and also by controlling a rate of slow air bleed by an exhaust sensor.
CONSTITUTION: A by-pass air passage 16 is opened into an inlet passage 2 in the downstream of a throttle valve 3g of a carburetor 3, and the first electromagnetic valve 17, which is switch-controlled by the first control circuit 19 to which signals from a speed sensor 18 of an engine 1, are input is provided at the top of said passage 16. A slow auxiliary air bleed 10 which is equipped with the second electromagnetic valve 15 at the top is opened into a slow system fuel passage 3f, and the electromagnetic valve 15 is switch-controlled by the second control circuit 19 which receives signals from an exhaust sensor 20 provided in an exhaust passage 4. Then, a ratio of a control time of the second control circuit 21 is set to be greater than that of the first control circuit 19, and a great amount of control air is controlled by the second electromagnetic valve 15.
