    • A fuel injection controller performs minute injection amount learning for learning an injection characteristic of an injector related to a minute amount injection such as a pilot injection by performing n-times of injections of fuel amounts obtained by equally dividing a fuel injection amount required during idle rotation speed control. The controller performs relative injection amount learning for learning a variation in the injection characteristics among cylinders based on a correlation between output torque of an engine and the injection amount when the injections of the equally-divided fuel amounts are not performed. Learning areas of the minute amount injection learning and the relative injection amount learning are defined by the injection amount and fuel pressure such that the learning areas do not interfere with each other.
    • 燃料喷射控制器通过执行n次喷射燃料量来执行喷射量的学习,该喷射量学习用于学习与诸如先导喷射之类的微量喷射相关的喷射器的喷射特性,该燃料喷射量是通过将在空转期间所需的燃料喷射量相等而获得的燃料量 速度控制。 控制器执行相对喷射量学习,用于基于发动机的输出转矩与未分配燃料量的喷射量之间的相关关系来学习气缸之间的喷射特性的变化。 通过喷射量和燃料压力来限定微量注入学习和相对注入量学习的学习区域,使得学习区域彼此不干涉。

    • An injection valve includes a housing that movably accommodates a needle. A movable core is axially movable together with the needle in the housing. A stationary core is fixed in the housing for forming a magnetic circuit together with the movable core. At least one of the movable core and the stationary core has an end that has an annular first protrusion protruding toward an end of an other of the movable core and the stationary core. At least one of the movable core and the stationary core has an end that has an annular second protrusion protruding toward an end of an other of the movable core and the stationary core. The first protrusion is substantially coaxial with respect to the second protrusion.
    • 注射阀包括可移动地容纳针的壳体。 可移动的芯可与针一起在壳体中轴向移动。 固定铁芯固定在外壳中,与可动铁芯一起形成磁路。 可动芯和固定芯中的至少一个具有端部,该端部具有朝向可动芯体和固定芯部中的另一个的端部突出的环形第一突起。 可动芯和固定芯中的至少一个具有端部,该端部具有朝向可动铁芯和固定铁芯中的另一个的端部突出的环形第二突出部。 所述第一突出部相对于所述第二突起基本上是同轴的。
