ABSTRACT:
A device for controlling air-fuel ratio for an internal combustion engine with a use of the signal from an oxygen sensor adjacent to a three-way catalytic converter, the device comprising throttle sensor for detecting the transient running state of the engine and supplying the detected signal to a controller, integration by an integration circuit in the controller being commenced at a predetermined value produced in an initial voltage setting circuit in the controller, regardless of the preceding value of the output of the integration circuit, in such a transient state as a sudden deceleration.
