ABSTRACT:
A fuel injection controlling system for an internal combustion engine comprising an oscillator circuit for generating clock pulses having a frequency corresponding to the air-to-fuel ratio of the mixture, a first detecting circuit for generating pulse signals having a time width corresponding to the rate of air flow to the engine, a first multiplier circuit for generating an output corresponding to the product of the air-to-fuel ratio and the rate of air flow in a binary coded form, a second detecting circuit for generating signals having a pulse width proportional to the rotational speed of the engine, a second multiplier circuit for generating an output corresponding to the product of the air-to-fuel ratio and the rate of air flow and the rotational speed of the engine in a binary coded form, and a conversion circuits for generating pulse signals each corresponding to the output of the second multiplier circuit, whereby fuel injection valves are actuated by the output of the conversion circuit.
