摘要： The fuel injection system includes an injector 7 to be electromagnetically driven, a control device 2 for outputting a drive signal having first current-carrying time T1 and second current-carrying time T2 to this injector 7, and a drive device 6 for passing a large current to open a valve of the injector 7 during the first current-carrying time T1 and passing a small current to hold the injector 7 in a valve opening state during the second current-carrying time T2. The system is constructed so that the first current-carrying time T1 is set to the time shorter than valve opening required time T0 from a current-carrying start of the injector 7 to full opening and this time difference is set to the value shorter than valve closing operation delay time from a current break of the injector 7 in the case of breaking a current in the first current-carrying time T1 to a start of a valve closing operation.
