したことを特徴とする燃料噴射弁。The main body has an injection port at its tip, and a main body that communicates with the injection port to form a fuel supply path, and a needle valve that opens and closes the injection port, which is slidably provided in the main body. In a fuel injection valve configured to introduce pressurized fuel to a pressure receiving surface at an end on an injection port side through the fuel supply passage, a needle valve is disposed in the main body on a side opposite to the injection port, facing the needle valve. a needle valve lift control device that operates according to the difference between the pressure receiving area of the needle valve and the pressure receiving area of the needle valve and limits the amount of lift of the needle valve; and a portion branched from the fuel supply passage and communicating with the needle valve lift control device. - a branch passageway disposed at the branching position and controlling the opening and closing of the branch passage; a switching valve that detects engine idle or a light load low speed state to drive the switching valve and transfer pressurized fuel to the needle valve; and a drive means leading to a lift control device, the lift amount of the needle valve is limited to reduce the fuel injection rate and lengthen the injection period when the engine is idling or under light load and at low speed. fuel injection valve.
