PURPOSE: A hybrid fuel injection device for a diesel engine is provided to optimize the engine performance as fuel injection timing is easily controlled in a fuel injection valve by a screw for adjusting the opening pressure. CONSTITUTION: A hybrid fuel injection device for a diesel engine comprises an electric control method and a mechanical fuel injection method. The electronic control method and mechanical fuel injection method perform a pre-main-post injection by maintaining high pressure only for a fuel injection period. A groove is formed on the plunger of a fuel injection pump. A high pressure fuel injection pump easily control the fuel injection timing by gently increasing initial pressure after the initial pressure rapidly increases. |
