<P>PROBLEM TO BE SOLVED: To contribute to cost reduction by securing a high voltage for accurately operating a fuel injection valve in a short time to thereby achieve stable fuel supply, and by reducing capacity of an individual boosting circuit and relaxing part performance, and so forth, in a fuel injection device of an internal combustion engine. <P>SOLUTION: The device includes: a plurality of first energy storage elements which supply high voltages to a fuel injection electromagnetic valve; a boosting circuit which boosts a battery voltage, and charges the first energy storage elements; and second energy storage elements which accumulate the electrical energy of the battery voltage. The device also includes a switching circuit which moves the electrical energy via the second energy storage elements between the plurality of energy storage elements. <P>COPYRIGHT: (C)2012,JPO&INPIT |
