“转子”头安装在分电器轴的顶部,分电器轴由发动机凸轮轴上的齿轮驱动,从而与其同步。该转子压在分电器盖中心端子上的碳刷上,该碳刷连接到点火线圈。在HEI系统中,转子头通过顶部直接连接到线圈;在点火系统中,转子头通过中心端子连接到线圈,并进行远程连接。
转子的结构使得中心极片与其外缘电连接,这样进入中心极柱的电压就会通过碳点传导至转子的外缘。随着凸轮轴旋转,转子也随之旋转,其外缘会经过每个内部火花塞端子,从而点燃每个火花塞。

The "rotor" head is attached to the top of the distributor shaft which is driven by a gear on the engine's camshaft and thus synchronized to it. This rotor is pressed against a carbon brush on the centre terminal of the distributor cap which connects to the ignition coil either through the top and wired directly to the coil in HEI systems, or via the centre terminal in points ignition systems and remotely connected to the coil.
The rotor is constructed such that the centre tab is electrically connected to its outer edge so that voltage coming in to the centre post travels through the carbon point to the outer edge of the rotor. As the camshaft rotates, the rotor spins and its outer edge passes each of the internal plug terminals to fire each spark plug.

转子臂和接触点套件——经典保时捷车型的精密点火组件
转子臂和触点组是保时捷点火系统的重要组成部分,负责控制采用机械点火装置的车辆的火花分配和正时。它们共同确保正确的点火顺序,从而实现可靠的燃烧、平稳的加速和高效的发动机性能。
在 Design911,我们为经典和早期保时捷车型(包括 911、912、914、924 和 928)提供全系列正品高品质转子臂和接触点组。每个组件都经过精心设计,以实现精密配合、持久性能和一致的电力输送 - 保持您的保时捷的原创性和可靠性。
转子臂和接触点起什么作用?
在传统的基于分电器的点火系统中,这些组件协同工作以产生和分配燃烧所需的火花:
- 转子臂:在分电器盖内旋转,将点火线圈的高压电流依次传输到每个火花塞端子。
- 接触点:与发动机旋转同步打开和关闭电路,控制线圈放电和点火正时。
- 共同作用:它们保持准确的火花正时,以实现平稳运行和高效的动力传输。
这些部件对于保持经典保时捷发动机可靠运转和最佳性能至关重要。
为什么转子臂和接触点会失效?
随着时间的推移,热量、摩擦和磨损会影响这些点火部件的性能。常见的故障原因包括:
- 电弧引起的触点磨损或点蚀。
- 积碳会降低火花效率。
- 转子臂因高电压或振动而腐蚀或破裂。
- 由于行驶里程和年限而导致的机械疲劳。
- 分配器外壳腐蚀或污染。
故障症状包括启动困难、失火、发动机犹豫或动力损失,尤其是在高转速或负载下。
为什么要更换磨损的转子臂和接触点?
更换磨损或损坏的点火部件可恢复精准的火花正时和平稳的发动机性能。全新高品质转子臂和接触点可提高燃烧效率,并防止点火系统进一步磨损。
