Abstract

Improvements in fuel injection control systems, for internal combustion engines, of the type featuring a control circuit for electrically controlling the opening time of an electromagnetically actuated fuel injection valve in response to engine crankshaft rotation and/or the pressure of the engine intake manifold, characterized in that said control circuit comprises: means for generating a signal that has a magnitude as a function of said pressure of said engine intake manifold; means for generating a pulse train having a repetition rate and a pulse duration as a function of each revolution of said engine crankshaft and a pulse magnitude that varies in a predetermined manner; means for comparing the magnitude of said pressure signal with the magnitude of the pulses of said pulse train and producing a resulting pulse train with a pulse duration that is an independent function of said pressure signal and each revolution of said crankshaft the motor; and means for feeding said resulting train of impulses to said fuel injection valve, electromagnetically actuated to change the opening time thereof in response to a change in the revolution of said crankshaft and/or in the pressure in the manifold. engine intake.
