The present invention relates to a fuel injection valve of a diesel-hydraulic fuel injection system is a fuel injection valve that allows fuel injection in a diesel engine to adjust the injection pressure of the fuel to improve the performance of the product.
The present invention to this, in the fuel injection valve of a fuel injection system for injecting fuel in a diesel engine, the valve housing 210 that is of the discharged high-pressure in the fuel injection pump (100) oil In is formed, the valve housing ( 210) is elastically supported piston 230 is a coil spring (S) therein is formed, and is formed with the injection plunger 220 to fall w, depending on the operation of the piston 230 at a lower portion of the piston 230, characterized in that is formed by a nozzle block 240, the fuel injection hole (243) formed so as to be operated by the fuel oil injected into the fuel oil port 213 is injected into the cylinder of the injection plunger 220.
