Abstract
The fuel injection device includes a plunger, operatively connected, to a cam driven by an engine, having control groups for use in communicating with an outer circumferential surface and an end surface of a fuel injection nozzle. The fuel injection device further includes a timing sleeve fitted outwardly of the plunger, for opening or closing the control groups and an actuator for driving a timing rod connected to the timing sleeve in such a way as to move the timing sleeve up and down against the plunger. Finally, the fuel injection device includes a control device for outputting a signal for performing moving-up or moving-down of the timing sleeve to the actuator, and inputting a signal from a source of operation information.
