ABSTRACT:
In feedback control for the air/fuel ratio based on a sensor producing an output signal proportional to a change in the air/fuel ratio, a control constant modifier is operative to vary the proportional component and the integration component in a feedback system in accordance with an air/fuel ratio set for controlling, thereby assuring stability of ultimate fuel control.
