Abstract

PURPOSE: To smooth the shifting operation of an engine from deceleration to acceleration by increasing the amount of air-bleed in an air-fuel ratio control device at the deceleration of the engine as memorizing the average air-fuel ratio, and then continuing to control on the basis of the air fuel ratio memorized at the acceleration.
CONSTITUTION: Air compensation passages 16 and 30 to compensate air-fuel ratio are connected to a main and a slow fuel passage 14 and 26, and solenoid valves 17 and 31 are arranged at their tops to be feedback and controlled by a control circuit 24. An O2 sensor 40 and revolution number negative pressure, and clutch switches 62W69 are connected to the circuit 24 for increasing the bleed air at deceleration to make the air-fuel ratio lens as memorizing the average value of the control air-fuel ratio before the deceleration in a memory. Then, controlling is carried out on the basis of the duty ratio of the memorized average air-fuel ratio at the time of acceleration after the deceleration.
