From the appearance, it is composed of two parts: magnetic silicon chip group and coil body. There are two connectors on the coil body, in which the circular hole is the high-voltage power output port, and the bipolar interface is the power supply interface of the primary coil. Its voltage comes from the ECU (), and the charging time is accurately controlled The ignition coil of QQ is installed at the bottom of the air filter tube and fixed on the iron frame on the side of the engine with two cross screws. The iron frame can be disassembled separately. The high-voltage electrical interface is upward and the input interface is downward, and the wiring is provided with a rubber protective sleeve In general, when the ignition coil of distributor ignition vehicle fails, all cylinders of the whole engine are affected, but the ignition system of QQ308 is slightly different. It is composed of three independent ignition coils, which control the ignition of three cylinders respectively. Therefore, the performance is not particularly obvious in case of failure. When the ignition coil of one cylinder fails, When the engine starts, there will be very obvious vibration (note that it is not vibration), and the idle speed is unstable. When driving at low speed, it is easy to rub the car (I feel the car running). When driving, the engine sound becomes louder, and the engine fault light occasionally lights up. When the three ignition coils have problems, the engine is difficult to start or cannot be started at all, the engine stalls during driving, and the idle speed decreases, These problems have a great impact on the engine. Because the ignition coil used in QQ308 is dry and sealed with sealant, it is very difficult to repair the ignition coil. Generally, it is replaced directly. When most of the ignition coils are damaged, the high-voltage wire is also easy to be damaged, so it needs to be replaced together
