The fuel injection apparatus has a high-pressure fuel pump and a fuel injection valve connected to it for each cylinder of the engine. The high-pressure fuel pump has a pump piston, which is driven in a stroke motion by the engine and defines a pump working chamber, which is connected by means of a line to a pressure chamber of the fuel injection valve that is disposed separate from the high-pressure fuel pump in the engine and has an injection valve member, which is used to control at least one injection opening and can be moved by the pressure prevailing in the pressure chamber in an opening direction, counter to a closing force, in order to unblock the at least one injection opening. An electrically actuated control valve is provided in the fuel injection valve and at least indirectly controls a connection of the pump working chamber to a relief chamber, which can store pressurized fuel diverted by the control valve when this valve is open.
