PROBLEM TO BE SOLVED: To provide vibration control action by the elasticity of a resin, and avoid damage and failure of action due to the vibration of a fuel rail itself or an injector, by forming the fuel rail of resin. SOLUTION: Fuel raised to a predetermined injection force, is dividedly led to flow into two fuel supply passages 88, 88, led to flow from bottom to top in a feel rail 89 being a fuel passage on a right bank 30a side, and supplied in order to injectors 38 of three air cylinders (#5, #3, #1) on the right bank 30a. Also, fuel is led to flow from bottom to top in a fuel rail 89 being a fuel passage on a left bank 30b side, and supplied in order to injectors 38 of three air cylinders (#6, #4, #2) on the left bank 30b. The fuel rails 89 are formed of a resin excellent in elasticity and heat insulation propertres. Hereby, vibration control action can be obtained by the elasticity of the resin, and damage and failure of action due to the vibration of the fuel rail 89 themselves or the injectors 38, can be avoided. |
