Abstract
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.
Claims4
A fuel injection system comprising:
- a plurality of injectors, which are operated through energization thereof;
- and
- a control device, which controls energization of each of the plurality of injectors to control an operational state of each of the plurality of injectors, wherein:
- the 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;
- and
- the control device includes an overlap correcting means for correcting an energization period of the next one of the plurality of injectors by lengthening the energization period of the next one of the plurality of injectors in comparison to a normal energization period of the next one of the plurality of injectors, which is set for a non-overlap injection operation of the next one of the plurality of injectors.
