How to determine if the ignition coil is damaged?

Although the ignition coil plays an important role in the ignition system, its construction is not complicated. The ignition coil is mainly composed of a primary coil, a secondary coil and the like. The ignition coil changes the low voltage provided by the battery to a high voltage, so that the spark plug generates an electric spark and then performs subsequent ignition. If the ignition coil is broken, is there any indication?

1. In the idle state, the body shake is obvious. Observing the exhaust pipe mouth, the exhaust gas flow discharged from the car has obvious intermittent, and the exhaust pipe is extremely shaken, and the sound of "burst" can be clearly heard;
2. During the driving process, when the speed is below 2500 rpm, the body has obvious jitter and acceleration is weak; when the speed exceeds 2500 rpm, the jitter disappears;
3. Open the engine cover and observe the running engine and find that the engine has obvious jitter. This kind of jitter is obviously not the jitter under normal engine operating conditions, and the jitter is large.
4. The ignition coil is not shipped, causing the car not to catch fire.
Generally, one ignition coil is responsible for one cylinder (the individual models will share one ignition coil for two cylinders). If only one ignition coil fails and the rest works normally, then the bare emergency travel is not a problem, but the engine, the base and the connection to the vehicle. Parts and so on are very unfavorable, it is best to hurry to the repair shop for maintenance. If more than one cylinder does not work, then the car is likely to turn off directly, then you can only call the trailer.
