Fuel injection equipment for internal combustion engine

A fuel injection equipment in combination with an internal combustion engine which does not have a battery serving as a control power supply comprising:

• a fuel injector including an exciting coil and injecting fuel into a fuel injected space of an internal combustion engine when said exciting coil is fed with an exciting current of a predetermined level or more;
• a fuel pump for feeding fuel from a fuel tank to said fuel injector;
• a fuel pump driving power supply for driving said fuel pump;
• a driving power circuit including an injector driving power supply and generating a driving voltage applied to said exciting coil;
• and
• an injector trigger circuit for permitting said exciting current to be fed from said driving power circuit to said exciting coil of said fuel injector when an injection command signal is fed thereto;
• said fuel pump driving power supply and injector driving power supply comprising a magneto driven by said internal combustion engine and having characteristics of being increased in output voltage or output current with an increase in engine rotation speed;
• said magneto comprising an AC multipolar magneto including a generating coil for said fuel pump driving power supply and a generating coil for said injector driving power supply which are arranged separate from each other.
