ABSTRACT:
Timer means for sequential fuel injection including a timer circuit triggered to develop an output signal after a time interval having a duration which varies as a linear function of the magnitude of one or more control voltages varied in accordance with operating parameters, one control voltage being preferably a conditioned speed signal and a second being preferably a conditioned intake manifold pressure signal. The voltage across capacitor means is varied as a linear function of a control voltage, using either a Miller ramp circuit or using a transistorized current sink and is applied to a triggering circuit in the form of a Schmitt trigger circuit or a dual input operation amplifier.
