ABSTRACT:
Circuitry is described for use with a fuel mixture control system of an internal combustion engine in which an oxygen sensor is located in the exhaust system and generates a generally bi-valued signal which is compared with a set-point voltage to indicate rich or lean mixtures. In order to permit control loop operation even when the sensor signal changes due to decreasing temperatures, the set point voltage is adjusted to remain between the two values of the sensor signal. This adjustment is effective only when the lower sensor signal exceeds a given limit.
