。[Scope of Claim for Utility Model Registration] 1. Supplying the main fuel in a dual fuel engine equipped with a pilot injection valve that injects pilot fuel and a main injection valve that injects main fuel that is more corrosive than the pilot fuel. A neutral position in which the main fuel passage for supplying the pilot fuel and the pilot fuel passage for supplying the pilot fuel are connected by a bypass passage, and a neutral position in which the bypass passage is closed and the main fuel passage is opened; A two-way fuel injection valve characterized in that it is provided with a switching means that can be switched to a switching position for stopping the supply of main fuel to the main injection valve, and a control means that moves the switching means to the switching position immediately before stopping the engine. fuel engine. 2. The dual fuel engine according to claim 1, wherein the control means is further configured to position the switching means at the switching position even when the engine is started. 3. The dual fuel engine according to claim 1 or 2, wherein stirring means is provided downstream of the bypass passage connecting portion of the main fuel passage.
