Abstract
In a fuel injection apparatus () configured so that high-pressure fuel from a common rail () is supplied to an injector () through a pressure booster (), it is discriminated whether reduction of the fuel pressure in the common rail () 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 () 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 () is not being conducted.
