Abstract
A fuel injection system equipped with a fuel increase command signal generator for an automotive internal combustion engine, comprising an airflow meter for measuring the airflow rate of the intake air for determining the pulse width of a pulse signal with which fuel injection valves are energized; and a fuel increase command signal generator for producing a command signal with which the fuel flow rate is momentarily increased. The fuel increase command signal generator includes a differentiator and a comparator for detecting the rate of decrease of the airflow, another comparator for detecting the opening degree of the throttle valve of the engine, and an AND gate for producing the fuel increase command signal so that the fuel flow rate is increased only when the rate of decrease of the airflow is over a predetermined value while the throttle valve is closed or nearly closed.
