What are the symptoms of a broken car ignition coil

With the development of automobile engines in the direction of high speed, high compression ratio, high power, low fuel consumption and low emissions, the traditional ignition device has not adapted to the requirements of this era. We know that the core components of the ignition device are the ignition coil and the switching device, which increase the energy of the ignition coil and the spark plug can produce a spark with sufficient energy. So the question is, what happens when the ignition coil breaks? Let's give you a popular science.

1. During driving, when the speed is below 2500 rpm, the body has obvious shaking, accompanied by weak acceleration; When the rotational speed exceeds 2500 rpm, the jitter will disappear.

Second, in the idle state, the shaking of the body is obvious; There is a significant interval in the exhaust gas flow from the exhaust pipe, and the exhaust pipe shakes strongly.

Third, the engine has obvious jitter, this jitter is obviously not the jitter under normal engine working conditions, and its jitter amplitude is large.

In response to the above situation, if only one ignition coil fails, and the remaining three cylinders are working normally, it is okay to barely drive in an emergency, but this will seriously damage the engine, base and other components. Therefore, it is recommended that the majority of car owners face the situation that the ignition coil of the car with more than 1 cylinder is burned, and it is recommended to stop driving immediately.
