<P>PROBLEM TO BE SOLVED: To prevent liquid fuel from being injected from injectors when the liquid fuel is mixed or generated in a fuel supply passage in a fuel rail used by fitting the top feed injectors from a lower side. <P>SOLUTION: This fuel rail 1 is used by fitting the top feed injectors 3 into a plurality of injector connection holes 13 opened at predetermined intervals in a longitudinal direction in the lower surface of a tubular member having the fuel supply passage 10, and equally distributes and supplies gaseous fuel having predetermined pressure to each cylinder of a gas engine through the plurality of injectors 3. When the fuel rail is attached to the gas engine, fuel introducing ports to the injectors 3 are opened in positions higher than a lowest bottom portion in the fuel supply passage 10 by a predetermined level or higher. Even if the liquid fuel is accumulated to the predetermined level in the fuel supply passage 10, the liquid fuel is prevented from being led to flow into the injectors 3 as it is. <P>COPYRIGHT: (C)2010,JPO&INPIT |
