特徴とするデイーゼルエンジンの燃料噴射装置。 Between the plunger chamber outlet of the fuel injection pump and the injection nozzle, it moves according to the oil pressure of the fuel pressured from the plunger chamber outlet, and pushes out the fuel on the downstream side toward the injection nozzle side according to the amount of movement. ,
A delivery valve that opens a fuel passage from the plunger chamber outlet to the injection nozzle when the amount of movement becomes large is provided downstream of the delivery valve, and communication with the fuel passage is cut off by the movement of the delivery valve. A fuel injection system for a diesel engine, characterized in that an oil chamber capable of filling fuel is provided and has a communication passage where fuel can be filled, and a rod-shaped member that is biased so as to be able to move in and out of the oil chamber faces the oil chamber. Device.
