Abstract : This patent discloses engine fuel injector control circuitry comprising a pulse generator that produces long duration pulses. NOR gate circuitry is actuated by each pulse to operate a ramp generator. The output changes at a rate determined by current flow generated by an engine speed sensor. Ramp generator output is applied to an input terminal of a comparator to produce rapid switching of the comparator output for starting the injection of fuel into an engine cylinder. Injection is terminated by the trailing end of the long duration pulse. (Author)
