ABSTRACT:
Disclosed herewith an air/fuel ratio control device for and internal combustion engine which is capable of carrying out either feedback control or open loop control. In feedback control, a signal indicating the concentration of exhaust gas components is generated and fed to a fuel supply control device. In open loop control, a fuel injection rate is determined corresponding to intake air flow rate. For switching between feedback control and open loop control, the air/fuel ratio control device is provided with a means for detecting an abnormal condition of signal, and a means operative in response to the abnormal signal to interrupt feedback control. The air/fuel ratio control device is further provided with a means for detecting stopping of the abnormal signal and for returning control operation to feedback control.
