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。
The signal read out of the sensor is to be filtered, amplified, shaped and synthesized and then transformed into a digital pulse one, which is equivalent to the ignition time delay.
传感器检出的信号送入信号处理电路后，经滤波、放大、整形及合成，成为等效于滞燃期的数字脉冲信号。
