ABSTRACT:
An acceleration enrichment feature for an electronic fuel injection system is disclosed. The enrichment feature includes an operating parameter enrichment circuit which provides an acceleration signal proportional to the rate of change of an engine operating parameter that is indicative of a desired acceleration. The acceleration signal is combined with an off-closed throttle enrichment signal and the combination is transmitted to a peak detect and decay circuit which produces a control voltage signal equivalent to the peak of the two signals. The control voltage signal from the peak detect and decay circuit is used to regulate a voltage controlled current sink generating an acceleration enrichment signal which varies the termination threshold of the main pulse generation. Additionally included is a warm-up multiplier circuit which varies the acceleration enrichment signal as a function of the engine coolant temperature.
