<p>The invention is intended to provide a fuel injection device capable of reducing NOx in exhaust gases while satisfactorily maintaining the fuel consumption rate, and also provide a diesel engine having the same. This fuel injection device comprises a pressure accumulator for accumulating pressure-increased fuel, a fuel injection valve for injecting fuel by being opened in response to the feeding of fuel from the pressure accumulator, a feed passageway for feeding fuel to the fuel injection valve from the pressure accumulator, and two magnetic valves connected in parallel to the feed passageway and adapted to individually make or break the feeding of fuel to the fuel injection valve. And one magnetic valve has its fuel flow rate during opening thereof set at a value lower than that for the other magnetic valve during opening thereof. In feeding fuel to the fuel injection valve, the magnetic valve is first opened and then the other magnetic valve is opened.</p> |
