    • An ignition coil for a spark ignition engine generally includes primary and secondary windings disposed about a magnetic core. The secondary winding is wound around a spool. The spool includes a cylindrical body having opposite first and second ends and a winding section between the ends. A conical winding surface at one of the ends tapers from a large diameter at the one end to a smaller diameter. A grooved surface extends axially toward another of the ends of the body and extends to adjacent the smaller diameter of the conical surface. The grooved surface contains longitudinally spaced continuous circular grooves that have unequally angled sides. The sides toward the one end are sloped at a greater angle relative to a radial direction than are the sides toward the other end. The secondary winding is wound around the winding section forming a plurality of turns of wire wound one over the other at a desired angle. The grooves are sized such that only one turn of the wire is disposed within each groove.
    • 用于火花点火发动机的点火线圈通常包括围绕磁芯设置的初级和次级绕组。 次级绕组缠绕在线轴上。 卷轴包括具有相对的第一和第二端部以及端部之间的卷绕部分的圆柱体。 其中一端的锥形绕组表面从一端的大直径逐渐变细至较小的直径。 槽形表面轴向延伸到本体的另一端部并且延伸到邻近锥形表面的较小直径。 带槽的表面包含具有不等角度的侧面的纵向间隔开的连续圆形凹槽。 朝向一端的侧面相对于朝向另一端的侧面相对于径向方向以更大的角度倾斜。 次级绕组缠绕在绕组部分上,形成以所需角度彼此缠绕的多匝线。 这些槽的尺寸使得只有一匝的线被设置在每个槽内。

    • An ignition coil for a spark ignition engine includes a cylindrical magnetic core having opposite first and second ends. Preferably, the magnetic core has a circular cross section. Permanent magnets similarly shaped as the core are disposed at the ends of the magnetic core. The magnets are made from a microencapsulated magnetic material, resulting in increased resisitivity and decreased eddy current loss. By using the microencapsulated magnets, the voltage output of the ignition coil is increased while requiring no additional input energy. A primary winding is wound about the magnetic core between the first and second ends. A secondary winding assembly is disposed about the primary winding and the core. The secondary winding assembly includes a spool and secondary winding wound thereon. The secondary winding is inductively coupled to the primary winding. An outer case is disposed about said magnetic core, magnets and the primary and secondary windings.
    • 用于火花点火发动机的点火线圈包括具有相对的第一和第二端的圆柱形磁芯。 优选地,磁芯具有圆形横截面。 类似于芯的形状的永磁体设置在磁芯的端部。 磁体由微胶囊化的磁性材料制成,导致增加的电阻率和降低的涡流损耗。 通过使用微胶囊化磁体,点火线圈的电压输出增加,而不需要额外的输入能量。 初级绕组缠绕在第一和第二端之间的磁芯周围。 次级绕组组件设置在初级绕组和芯周围。 次级绕组组件包括缠绕在其上的线轴和次级绕组。 次级绕组感应耦合到初级绕组。 外壳围绕所述磁芯,磁体和初级和次级绕组设置。
