Fuel injection system executing overlap injection operation

摘要

A control device executes an overlap injection operation, in which one of the plurality of injectors is energized first to inject fuel, and a next one of the plurality of injectors is energized to inject fuel after starting of the energization of the one of the plurality of injectors while the one of the plurality of injectors is still kept energized. The control device corrects an energization period of the next one of the injectors by lengthening the energization period of the next one of the injectors in comparison to a normal energization period of the next one of the injectors, which is set for a non-overlap injection operation of the next one of the plurality of injectors.
