ABSTRACT:
A fuel injection system for an internal combustion engine capable of being normally operated while using an output of a generator driven by the internal combustion engine as a power supply therefor. The system includes a switching circuit for switching a driving current fed to an injector from a main power circuit which uses the output of the generator as a power supply therefor. The switching circuit is controlled by a switch control circuit for which a power supply comprises a control power circuit. The control power circuit includes a storage unit for storing electric power therein, so that the storage unit may be act as a power supply when the output of the main power circuit is reduced, to thereby feed the switch control circuit with a power supply voltage of a level equal to or above an operable level. The storage unit is charged by the output of the main power circuit or an output of a generating coil for a control power supply provided in the generator in a manner to be separate from a generating coil for the main power supply.
