Abstract
Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, port fuel injection timing is adjusted to reduce particulate matter formation in the engine so that particulate filter loading may be reduced until a time when the particulate filter may be purged.
