Abstract
The fuel injection system includes an injector to be electromagnetically driven, a control device for outputting a drive signal having first current-carrying time T and second current-carrying time T to this injector , and a drive device for passing a large current to open a valve of the injector during the first current-carrying time T and passing a small current to hold the injector in a valve opening state during the second current-carrying time T . The system is constructed so that the first current-carrying time T is set to the time shorter than valve opening required time T from a current-carrying start of the injector 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 in the case of breaking a current in the first current-carrying time T to a start of a valve closing operation.
