ignition coil primary winding的意思|示意

Ignition coil primary winding. Current flow through the coil produces an electromagnetic field, which is used to induce a high voltage in the secondary coil.

点火线圈初级绕组。电流通过线圈，产生一个电磁场，用来在次级线圈中产生高电压。

The electronic control unit allows current to flow through the ignition coil primary winding until it senses a triggering voltage pulse from the speed sensor, or pickup coil.

电子控制单元使电流通过初级绕组直到感知到一个从转速传感器或拾波线圈产生的触发电压脉冲。
