In general, what is the life span of the ignition coil?

Normally, each cylinder is equipped with a set of ignition coils and spark plugs, and the service life of the ignition coil will generally be 100 thousand kilometers or even longer.

For car owners, if we want to make the ignition coil life longer, we should pay attention to the use of spark plugs. The use of old spark plugs will increase their work load. In addition, we should pay attention to the water temperature of the car, and the ignition coil of the vehicle with high water temperature is easy to burn. The reason why the low voltage power of the car can be turned into high voltage is that there is the same form as the ordinary transformer, and the ratio of the turn number of the primary and secondary coils is larger. But the way of operation is different from the ordinary transformer. The common transformer is continuously working, while the ignition coil is interrupted. It restores energy and energy at different frequencies according to the engine's different speed.

The fault of the ignition coil is often due to the poor quality of the fuel, the fuel can be fully burned, resulting in excessive carbon spark plug, the ignition coil will be breakdown leads to damage of ignition coil assembly.

Based on the protection of the ignition coil, usually drive when you need to pay attention to the following aspects: to prevent the ignition coil heat or damp; when the engine is not running and don't open the ignition switch; regular inspection, cleaning, fastening line joint, avoiding the short circuit or ground; control of engine performance, prevent excessive voltage; spark plug is not a long-term "hanging fire"; the ignition coil water can dry cloth, no fire baking, otherwise it will damage the ignition coil.
