PROBLEM TO BE SOLVED: To provide a constitution capable of pressure-feeding fuel to a pressure accumulation container much more excellently than conventional constitution.SOLUTION: A fuel injection device comprises an injector, a pressure accumulation container, a fuel pressure-feeding pump, and a pressure-feeding control part. The fuel pressure-feeding pump is provided with a pressure-feeding control valve. The pressure-feeding control valve is an electromagnetic valve provided to control existence of the pressure feeding and a pressure-feeding amount of the fuel into the pressure accumulation container. The pressure-feeding control part controls the pressure-feeding control valve so that change of rail pressure (internal pressure of the pressure accumulation container) due to the pressure-feeding of the fuel in the fuel pressure-feeding pump is within a predetermined range, and pressure-feeds the pressure-feeding amount corresponding to plural times of fuel injection to the fuel pressure-feeding pump at a time. |
