Abstract
Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, different duration port fuel injection windows are provided to maximize fuel injection amount and improve accuracy of an amount of fuel injected during a cylinder cycle via port and direct fuel injectors.
