Abstract:
A fuel injection control system for controlling the transition from an active fuel injection waveform to another fuel injection waveform in an electrically controlled multiple shot fuel injection system comprising:at least one fuel injection device operable to deliver a plurality of fuel injection shots; an electronic controller coupled to the at least one fuel injection device; the controller being operable to determine a potential waveform based upon current engine operating conditions; the controller being operable to set loop fuel hysteresis values; the controller being operable to determine a loop fuel change; the controller being operable to compare the loop fuel hysteresis values with the loop fuel change; and the controller being operable to change the active waveform to the potential waveform if the loop fuel change is greater than the loop fuel hysteresis values for longer than a selected period of time.
