Abstract:
Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, a port fuel injection window is shorted to provide time for scheduling a direct fuel injector pulse width so that the direct fuel injector pulse width may be adjusted so that a desired amount of fuel enters a cylinder.
