An apparatus and method for controlling fuel injection signals to an engine during a sudden acceleration event. The present apparatus and method includes an electronic controller coupled to the electronically controlled fuel injectors of the engine and operable to recognize a sudden acceleration condition based upon certain sensed conditions associated with the acceleration of the engine. The controller is further operable to increase the pull-in current level and/or the hold-in current level of the fuel injection signals to improve fuel injector performance, fuel consumption, and emissions when a sudden acceleration event is recognized. Shortening the duration of the fuel shots associated with the fuel injection signal helps offset additional electrical power requirements associated with the higher current levels.

1. A control system for controlling a fuel injection signal to an electronically controlled fuel injector during a sudden acceleration event of an engine comprising:an electronic controller coupled to the fuel injector, said controller being operable to output a fuel injection signal to the fuel injector and to control at least one of a current level and a current duration of said fuel injection signal; at least one signal providing mechanism coupled to said controller for inputting a signal thereto indicative of an acceleration of the engine, said controller being operable to recognize an acceleration event of the engine based upon said input signal; said controller being further operable to increase at least one of a current level and a current duration of at least a portion of said fuel injection signal when a sudden acceleration event is recognized; wherein said fuel injection signal includes a pull-in current level and a pull-in current duration and a hold-in current level, said controller being operable to increase at least one of said pull-in current level, said pull-in current duration, and said hold-in current level when a sudden acceleration event is recognized.
