  1. The principle of ignition coil

everybody knowsSpark plugNeed to be replaced regularly, but many people ignore the maintenance of other parts of the ignition system, such as ignitionHigh-voltage linelock up. When the engine is running, there is a high-voltage pulse current of tens of volts on the ignition coil. Due to its long working time in high temperature, dust and vibration environment, it will inevitably cause aging and even damage.

The simple explanation of the ignition coil is that it allows the spark plug to "ignite" the cylinder part of the mixed gas. In fact, it is a transformer that converts the low-voltage current of the vehicle into high-voltage electricity.

two, Ignition coil failure performance

The most obvious feature of ignition coil failure is the lack of engine cylinders. When the engine is idling, there may be a clear cracking sound, accompanied by severe engine shaking, it may be that the ignition coil is broken.

And if the ignition coil fails, the higher the gear, when refuelingcarThe more obvious the frustration of the engine, the more severe the engine shake, the smoother the oil, the better, and the intense oil is the best experience, even the feeling of stalling.

  Third, the reason for the burning of the ignition coil
Why is the car ignition coil always broken?
  The main faults of the ignition coil are as follows:

Coil breakdown: no high voltage output, no ignition;

Coil short circuit: low voltage, insufficient energy; spark plug electrode carbon black, severe engine shaking;

Surface discharge: ignition coil burnout;

Poor insulation: Insulation (vulnerable parts) caused by vehicle vibration, engine high and low temperature changes, corrosive environment, loss of insulation materials, etc.;

Spark plug: The electrode gap is too large, which increases the boost load of the ignition coil and breaks down the high voltage coil, resulting in a short circuit or circuit breakdown

The ignition coil plays a vital role in the ignition system. In the daily maintenance of the ignition system, the owner should not put the ignition coil aside while paying attention to accessories such as spark plugs.
