摘要： A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions of the engine, the controller being operable to output a fuel injection signal to the fuel injector to deliver a first, a second, and a third fuel shot to the cylinder during a fuel injection event based upon the sensor signals. The controller also delivers each of the multiple fuel injection shots within defined cylinder piston displacement parameters during a particular piston stroke, within defined fuel apportionment limits, and within defined delay limits between each respective fuel shot so as to control exhaust emissions.

摘要： 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.
