Disclosed is a mechanical fuel injection valve. According to the present invention, the mechanical fuel injection valve compresses an elastic member while a needle rises in a direction of opening an injector of a valve body such that a support member is modified by the weight applied to the support member from the elastic member. In addition, the mechanical fuel injection valve measures a fuel injection time when the fuel is injected to a combustion chamber by using the degree of the modification of the support member. In other words, the mechanical fuel injection valve measures the fuel injection time by using the degree of the modification of the support member modified according to the motion of the needle moving to inject the fuel. Therefore, the fuel injection time can be accurately measure. |
