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 duration of a port fuel injection window is increased to improve engine performance and a direct fuel injector fuel pulse width is dynamically adjusted to improve accuracy of an amount of fuel delivered during a cylinder cycle.
