Abstract:
A control system for controlling multi-shot fuel injection signals to a direct fuel injection device in a compression ignition engine, said control system comprising:an electronic controller coupled to the fuel injection device, said controller being operable to receive a plurality of signals indicative of an engine operating condition prior to an injection event, said controller being operable to output a signal indicative of a multi-shot fuel injection to the fuel injection device; at least one signal providing mechanism coupled to said controller for inputting a signal thereto indicative of an acceleration or deceleration of said engine; said controller being operable to recognize an acceleration or deceleration condition based upon said input signal; and said controller being further operable to determine a desired amount of fuel to be injected into an engine cylinder as a function of said engine operating condition prior to said injection event, partition said desired amount of fuel among a plurality of fuel shots of said injection event, determine whether said acceleration or deceleration event is recognized, disable a fuel shot in response to recognizing an acceleration or deceleration event, repartition a fuel amount allocated to said disabled shot among other fuel shots, and produce said output signal.
