PROBLEM TO BE SOLVED: To eliminate necessity for an additional constitutional part for a high fuel injection pressure relating to the conventional fuel injection valve for supply of a second medium particularly water, so that the fuel injection valve can be mounted in an existing internal combustion engine without an additional change process for injection of fuel and water. SOLUTION: In a fuel injection valve for an internal combustion engine, in a type providing a pressure passage connectable to a fuel high pressure source opened in a pressure chamber and a second inflow pipe line 39 so as to supply a second medium to an injection cross section of the fuel injection valve through the second inflow pipe line, the second inflow pipe line is completely extended in a valve main unit 3, to be opened directly in the pressure chamber or in a chamber formed between a valve member 9 and a wall surface of a hole at least in the vicinity of the pressure chamber. |
