    • A fuel injection valve includes: a needle valve including a seat portion on a tip side thereof; a nozzle body including a seat surface on which the seat portion is placed, and a swirl stabilization chamber on a downstream side of the seat surface, the nozzle body having an injection hole formed so as to have an inlet in the swirl stabilization chamber; a swirl flow generating portion having swirl grooves configured to give a swirling component to fuel to be introduced into the swirl stabilization chamber; and a fuel collision portion provided in a tip portion of the needle valve, the fuel collision portion being configured such that, in a state where the needle valve is opened, the fuel collision portion intersects with a virtual surface extended toward the injection hole from the seat surface included in the nozzle body. This allows dead fuel to be retained in the swirl stabilization chamber and to be introduced into the injection hole in a state where a swirling component has been given to the dead fuel from fuel having the swirling component.
    • 一种燃料喷射阀,包括:针阀,包括在其顶端侧的座部; 一个喷嘴体,其包括一个座位表面,座位部分放置在该座面上;一个旋流稳定室,位于该座表面的下游侧,该喷嘴主体具有形成为在该旋流稳定室中具有入口的喷射孔; 涡旋流产生部分具有涡旋槽,其构造成给涡流稳定室中引入燃料的旋动分量; 以及设置在针阀的前端部的燃料碰撞部,所述燃料碰撞部构成为,在所述针阀打开的状态下,所述燃料碰撞部与从所述喷射孔延伸的虚拟表面相交, 包括在喷嘴体内的座面。 这允许死燃料被保持在旋流稳定室中并且在从具有旋动分量的燃料向已停止的燃料提供旋转部件的状态下被引入到喷射孔中。
