How long is the life of the ignition coil?

According to the magnetic circuit, the ignition coil is divided into two types: open magnetic type and closed magnetic type. Under normal circumstances, each cylinder is equipped with a set of ignition coil and spark plug, and the service life of the ignition coil is generally 100,000 kilometers or more.

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.

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.

Based on the protection of the ignition coil, you need to pay attention to the following aspects when driving:

1. Prevent the ignition coil from being heated or damp;

2. Do not turn on the ignition switch when the engine is not running;

3. Frequently check, clean, and tighten the circuit connectors to avoid short circuits or grounding;

4. Control the engine performance to prevent excessive voltage;

5. The spark plug must not be “hanging” for a long time;

6. The moisture on the ignition coil can only be wiped dry with a cloth, and must not be baked with fire, otherwise it will damage the ignition coil.

The above introduction is just to provide you with a reference, you should pay more attention to it when driving. Especially for some novices, it is necessary to develop a good driving habit, and regular maintenance of the car is indispensable.
