ABSTRACT:
An air flow rate compensation circuit is provided to compensate for an erroneous air flow rate signal produced in response to the movement of the flap of an air flow meter disposed in the intake air passage of an internal combustion engine where the erroneous nature of the signal occurs because of an overshoot characteristic of the flap. The compensation circuit produces an output signal with which either an air/fuel ratio control signal produced in response to the air flow rate signal or the air flow rate signal per se is modified where the output signal is produced in response to the movement of the throttle valve or the variation of the air flow rate signal.
