Abstract

An auxiliary circuit means is disclosed herein for controlling actuation of an injector valve means to provide for cold starting of an engine. The circuit and injector means are energized when a vehicle ignition system is energized and the fuel for cold starting is provided during the period of time required for a selected voltage value to raise to a threshold value. The threshold value is determined by a voltage divider including a temperature responsive element sensing engine temperature. Means are provided to prevent noise and supply voltage variations from affecting the capability of the circuit to compute a cold start injection pulse of requisite duration.
