Abstract:
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.
