<P>PROBLEM TO BE SOLVED: To provide a fuel injection device for an internal combustion engine that effectively improves combustion reaction of fuel. <P>SOLUTION: The fuel injection device of an internal combustion engine includes: an injector I having a nozzle body 30 in which a needle valve 33 is housed movably in an axial direction; and an injection hole 31 formed at a tip end side of the nozzle body 30, and from which a high-pressure fuel supplied into the nozzle body 30 from a common rail is injected by the movement of the needle valve 33 in the axial direction. The fuel injection device is provided with: a high-voltage power supply device 10 for applying a voltage to the tip end of the nozzle body 30; and a control unit 20 for controlling the high voltage power supply device 10 such that a voltage is applied to the tip end of the nozzle body 30 while being synchronized with the injection of high-pressure fuel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
