ABSTRACT:
A control system including a microprocessor for controlling the controlled variables of an internal combustion engine, especially, the flow rate of fuel is disclosed. An air flow meter provides an output signal having such a non-linear characteristic relative to the flow rate of intake air that the signal level increases in the region of the small flow rate of intake air. The microprocessor carries out necessary digital computation on the basis of the output signal of the air flow meter to provide a fuel flow rate control signal. This digital control signal is converted into a signal having a linear characteristic proportional to the flow rate of intake air, or after having been produced from the microprocessor, converted into a signal including information proportional to the flow rate of intake air.
