Many of the many parts of a car play a key role, but are easily damaged by the working environment, such as spark plugs and ignition coils. If these important parts are abnormal during use, be sure to check them carefully and do not underestimate them. Many people say that the ignition coil does not need to live for a long life. If it is broken, it will be replaced and not expensive. So, in general, how often does the ignition coil change? In fact, the ignition coil does not have a fixed replacement cycle.
Everyone knows that spark plugs should be replaced regularly, but many people ignore the maintenance of other parts of the ignition system, for example, ignition high voltage coils. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition coil. Because it works in a high temperature, dusty, and vibrating environment for a long time, it will inevitably cause aging or even damage.
The simple explanation of the ignition coil is to allow the spark plug to "spark" and ignite the part of the mixed gas in the cylinder. Actually, it is a transformer that is responsible for converting the low-voltage current of the vehicle into high-voltage electricity. Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs, and the ignition coils are generally replaced at 100,000 kilometers or even longer.
However, the ignition coil should not be underestimated. If something is abnormal, it must be treated with caution. The damage of the ignition coil is easier to judge. When the vehicle suddenly experiences abnormal vibration (after a long mileage), accompanied by obvious loss of power, you should consider the possibility of ignition coil. The problem is. Once an abnormality occurs in the ignition coil, the spark plug will not work, and then the mixed gas of the cylinder will not deflagrate. When the vehicle loses a cylinder, the lack of power is natural.
