Many parts of automobiles play a key role, but they are easily damaged due to the influence of the working environment, such as spark plugs and ignition coils. These important parts, if there are abnormal conditions in use, must be carefully checked and not underestimated. Many people say that ignition coils don’t care about life expectancy, they can be replaced if broken, and it’s not expensive. So, in general, how often do the ignition coils be replaced? In fact, there is no fixed replacement cycle for the ignition coil.

Everyone knows that spark plugs need to be replaced regularly, but many people neglect the maintenance of other parts of the ignition system, such as the ignition high-voltage coil. When the engine is running, there is often a high-voltage pulse current of tens of thousands of volts on the ignition coil. Because it works in a high temperature, dusty, and vibrating environment for a long time, it will inevitably cause aging and even breakage.

The simple explanation of the ignition coil is to allow the spark plug to "generate a spark" to ignite the part of the mixed gas in the cylinder. In fact, it is a transformer 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. The ignition coils are generally replaced within 100,000 kilometers or even longer.

However, the ignition coil should not be underestimated at ordinary times. If there is any abnormality, it must be treated with caution. The damage of the ignition coil is easier to judge. When the vehicle is driving, the engine suddenly jitters abnormally (after driving a long kilometer), accompanied by obvious lack of power, then you have to consider the possibility of the ignition coil The problem is. Once the ignition coil is abnormal, the spark plug will not work, and the mixed gas in this cylinder will not deflagrate. When the vehicle loses one cylinder, the lack of power is natural.
