    • A high-strength ignition coil that can reduce stress produced in a coil case and prevent a casting material from being cracked when the ignition coil is mounted on an engine block. A coil case has a mounting flange on an outer surface thereof. A coil assembly is housed in the coil case. A casting material is filled into a gap between the coil case and the coil assembly and gaps which the coil assembly has. A plurality of first guide ribs are provided on an inner wall surface of the coil case or an outer surface of the coil assembly, for positioning the outer surface of the coil assembly with respect to the inner wall surface of the coil case. A limited area in which there is no first guide rib is provided on the inner wall surface of the coil case which faces the mounting flange, or the outer surface of the coil assembly which faces the mounting flange via the inner wall surface of the coil case.
    • 高温点火线圈,当点火线圈安装在发动机缸体上时,能够减轻线圈壳体产生的应力,防止铸造材料破裂。 线圈壳体在其外表面上具有安装凸缘。 线圈组件容纳在线圈壳体中。 将铸造材料填充到线圈壳体和线圈组件之间的间隙以及线圈组件具有的间隙。 多个第一引导肋设置在线圈壳体的内壁表面或线圈组件的外表面上,用于相对于线圈壳体的内壁表面定位线圈组件的外表面。 在线圈壳体的面向安装凸缘的内壁面或线圈组件的面向安装凸缘的外表面经由线圈壳体的内壁面设置有无第一引导肋的有限区域 。

    • An ignition coil of a dual ignition type that can prevent outputs from becoming unbalanced due to a difference in floating capacitance on wiring that connects secondary output terminals and ignition plugs together, thus realizing balanced outputs. A coil assembly housed in a housing as a coil case has a primary coil and secondary coils disposed concentrically with the primary coil. The secondary coils are comprised of two coils wound in opposite directions with the center of winding width being a boundary. The center of the winding width of the primary coil is shifted from the center of the winding width of the secondary coils by a predetermined width so as to balance outputs from the two secondary coils. A casting material is filled into a gap between the housing and the coil assembly and gaps which the coil assembly has.
    • 一种双点火型点火线圈,其可以防止输出由于将二次输出端子和火花塞连接在一起的布线上的浮动电容的差异而变得不平衡,从而实现平衡输出。 作为线圈壳体容纳在壳体中的线圈组件具有与初级线圈同心设置的初级线圈和次级线圈。 次级线圈由缠绕在相反方向上的两个线圈构成,绕组宽度的中心是边界。 初级线圈的绕组宽度的中心从次级线圈的绕线宽度的中心偏移预定的宽度,以平衡来自两个次级线圈的输出。 将铸造材料填充到壳体和线圈组件之间的间隙中以及线圈组件具有的间隙。
