Zusammenfassung:When a main injection is performed, a first timing that is a time earlier than a second timing is selected as the valve opening starting timing, and a first period that is the period of time shorter than a second period is selected as the control period. Also, when a pilot injection is performed, the second timing that is the time later than the first timing is selected as the valve opening starting timing, and the second period that is the time longer than the first period is selected as the control period. Thus, in an injector with increased valve opening responsiveness, the valve opening behavior of a control valve of the injector in fuel injection with a minute injection quantity can be stabilized without replacing a control device, particularly an EDU with that of a large current specification.
