Abstract: A first spring axially urges a needle valve toward an injection hole. A second spring axially urges a movable core toward a stationary core with an urging force that is smaller than an urging force of the first spring. A stopper is placed on one axial side of the movable core where the injection hole is located. The stopper limits movement of the movable core toward the injection hole to limit an amount of compression of the second spring.
Abstract translation: 第一弹簧轴向地将针阀推向注射孔。 第二弹簧以比第一弹簧的作用力更小的推动力将可动铁心轴向推向固定铁芯。 止动器被放置在可移动铁芯的注入孔所在的一个轴向侧上。 止动器限制可动铁芯朝向喷射孔的移动，以限制第二弹簧的压缩量。

Abstract: A fuel injection control device is applied to an internal combustion engine including a fuel injection valve and causes a valve body to be in a valve open state accompanying an energization of the fuel injection valve to inject fuel. The fuel injection control device acquires a dynamic parameter. The fuel injection control device acquires an injection amount parameter. The fuel injection control device calculates, based on the dynamic parameter, a dynamic correction value. The fuel injection control device calculates, based on the injection amount parameter, an injection amount correction value. The fuel injection control device corrects a fuel injection using the dynamic correction value and the injection amount correction value.
