摩托车点火分为蓄电池点火和磁电机点火两大类。其中磁电机点火又分为:有触点电感放电式点火电路和无触点电容放电式电子点火电路,而后者则采用可控硅作开关,取消了工作时不可靠的断电触点,利用电容放电快、能量大的优点,其点火效率高,且不怕火花塞脏污,所以得到广泛使用。一、电路工作原理磁电机无触点电容放电式电子点火电路如图1所示。其原理是: 断开点火开关启动时,永久磁铁旋转 Motorcycle ignition is divided into two types of ignition of the battery and magneto ignition. Magneto ignition which is divided into: contact inductance discharge ignition circuit and non-contact capacitor discharge electronic ignition circuit, while the latter is the use of thyristor switch, cancel the unreliable power failure contacts, the use of Capacitor discharge fast, the advantages of large energy, the ignition efficiency, and are not afraid of spark plug dirty, so widely used. First, the circuit works Magnetic motor non-contact capacitor discharge type electronic ignition circuit shown in Figure 1. The principle is: disconnect the ignition switch is started, the permanent magnet rotation
