<p>The present invention relates to a fuel injection valve of a hydraulic fuel injection system for a diesel engine, by which a fuel injection valve for injecting fuel into a diesel engine is configured to be capable of controlling the injection pressure of the fuel, and, accordingly, performance of the product can be improved. To this end, in a fuel injection valve of a hydraulic fuel injection system for a diesel engine, a valve housing (210) to which high-pressure fuel discharged from a fuel injection pump (110) and inputted is formed, a piston (230) elastically supported by a coil spring (S) inside the valve housing (210) is formed, an injection plunger (220) ascending or descending according the operation of the piston (230) at the bottom of the piston (230) is formed, and a nozzle block (240) having a fuel injection hole (243) formed thereon so that fuel implanted to a fuel hole (213) can be injected into a cylinder with the operation of the injection plunger (220).</p> |
