ABSTRACT:
In a fuel injection apparatus (1) configured so that high-pressure fuel from a common rail (2) is supplied to an injector (8) through a pressure booster (4), it is discriminated whether reduction of the fuel pressure in the common rail (2) is necessary, the spill amount of the high-pressure fuel necessary for pressure reduction is computed when pressure reduction is discriminated to be necessary, and a control solenoid valve (48) is open/close controlled to spill said spill amount of the high-pressure fuel to the low-pressure side at a time point when fuel injection from the injector (8) is not being conducted.
