    • A system for controlling an oxygen concentration in exhaust gases emitted from a combustion engine. An oxygen sensor which changes a resistance in response to a sensed presence and absence of oxygen in exhaust gases is connected in series with an electric power source and a transistor to produce an output voltage indicative of the sensed presence and absence of oxygen. A comparator compares magnitudes of the sensor output voltage with a predetermined magnitude. In response to an output voltage of the comparator, the transistor controls a biasing current flowing from the electric power source to the sensor so that, when either presence or absence of oxygen is sensed, the sensor output voltage is kept substantially at the predetermined magnitude irrespective of temperature dependent changes in the resistance of the oxygen sensor.

The system detects an inoperable period of the air-to-fuel ratio detector due to a low engine temperature and stops the feedback correction of the air-to-fuel ratio to prevent erroneous correction. Furthermore, during the full load operation and idling operation the system holds the feedback correction of the air-to-fuel ratio respectively at a little smaller and larger than the stoichiometric ratio irrespective of the output of the air-to-fuel ratio detector and enables to easily return to substantially the stoichiometric one when the engine operating condition returns to normal operation.
