Ignition Systems
点火系统能造成电击。 避免接触点火系统的部件和线路。
无断路器磁电机中的存储电容器可通过手动转动磁电机来充电。 即使在磁电机的线路线束断开时,存储电容器也能够充电。
如果点火开关位于 ON(接通)位置且线路线束为连接状态,存储电容器可放电,而火花塞将点燃。 火花塞将点燃聚积在缸里的任何燃气。 曲轴和被驱动设备可能会运动。 可能造成人身伤害。 被驱动设备可能会损坏。 积聚在排气系统里的燃气也可能被点燃。
将线路线束连接到无断路器磁电机之前,先将存储电容器接地放电。 按照以下步骤将存储电容器放电:
- 将导线的一端固定到磁电机壳体。
- 将导线的另一端连接到磁电机上线路线束的接头触针上。
当存储电容器放电时,您会听到"喀嚓"一声。
- 将所有接头触针接地。
这将确保磁电机中没有电荷。 一些无断路器磁电机有一个以上的存储电容器。
连接线路线束之前,将点火开关转到 OFF(断开)位置。 如果点火开关位于 OFF(断开)位置,当线路线束连接到磁电机时,存储电容器会立即向接地放电。
