To provide a fuel supply device for supplying gas fuel to an engine, which can suppress abrasion inside a fuel injection valve.SOLUTION: An engine 10 comprises a fuel supply device 40 that supplies gas fuel to the engine 10. The fuel supply device 40 comprises: a fuel container 42 that accumulates and stores gas fuel; an injector 21 that injects gas fuel so that it is burned in the engine; a fuel passage 41 that connects the fuel container 42 and the injector 21 and through which gas fuel flows; and an addition unit 50 that adds lubricant for improving the slidability inside the injector 21, to the gas fuel flowing through the fuel passage 41.SELECTED DRAWING: Figure 1 【課題】ガス燃料をエンジンに供給する燃料供給装置において、燃料噴射弁内部の摩耗を抑制することができる燃料供給装置を提供することを目的とする。【解決手段】エンジン１０は、ガス燃料をエンジン１０に供給する燃料供給装置４０を備えている。燃料供給装置４０は、ガス燃料を蓄圧貯蔵する燃料容器４２と、ガス燃料がエンジンで燃焼されるように噴射するインジェクタ２１と、燃料容器４２とインジェクタ２１とを接続し、ガス燃料が流れる燃料通路４１と、燃料通路４１を流れるガス燃料に、インジェクタ２１の内部の摺動性を向上させる潤滑剤を添加する添加部５０と、を備える。【選択図】 図１
