Abstract
An apparatus and method for controlling a multi-shot fuel injection signal during certain acceleration and deceleration conditions when a predetermined threshold emissions limit will be exceeded, the apparatus and method including an electronic controller coupled to the electronically controlled fuel injectors of the engine and operable to recognize the certain acceleration or deceleration conditions based upon certain sensed engine performance parameters. The controller is further operable to eliminate or disable one or more fuel shots associated with a multi-shot fuel injection signal to control emissions when the certain acceleration or deceleration conditions are recognized.
