ABSTRACT:
An acceleration fuel enrichment system is disclosed in which if the rate of increase of throttle position is determined as exceeding a predetermined minimum threshold (V.sub.1), asynchronous acceleration enrichment fuel control pulses are developed and effectively added to steady state synchronous base fuel control pulses provided by an engine control microprocessor. When the rate of throttle position increase falls below a preset level, the development of the asynchronous fuel control pulses is terminated and synchronous acceleration enrichment fuel pulses are provided which are effectively added to the base synchronous fuel control pulses. The durations of these synchronous acceleration enrichment pulses are initially fixed, but when a decrease in engine manifold pressure is sensed, these durations are determined in accordance with the rate of change of the magnitude of sensed engine manifold pressure. The development of all acceleration enrichment pulses, either synchronous or asynchronous, is terminated in response to either sensed engine manifold pressure decreasing over a time interval by more than a predetermined high threshold value (V.sub.3) or by sensed engine manifold pressure decreasing over a time interval by less than a predetermined low threshold value (V.sub.2) after a decrease of pressure over a time interval during the development of the acceleration enrichment pulses exceeded this low threshold value.
