Bir ateşleme bobininin ömrü nedir?

Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs. The lifespan of an ignition coil generally extends up to 100,000 kilometers or even longer.

For vehicle owners who want to prolong the lifespan of their ignition coils, it is important to pay attention to the use of spark plugs. Using aged spark plugs can increase its workload. Additionally, attention should be paid to the water temperature of the car, as ignition coils in cars with high water temperatures are prone to burn out. The reason why low-voltage electricity in the car can be transformed into high voltage is because of the same form as ordinary transformers: the ratio of primary coil to secondary coil turns is large. Fakat, the working mode is different from ordinary transformers. Ordinary transformers work continuously, while ignition coils operate intermittently, storing and releasing energy at different frequencies according to different engine speeds.

Commonly, faults in the ignition coil are often due to poor fuel quality, resulting in incomplete combustion of fuel, excessive carbon deposit on spark plugs, and eventual breakdown of the ignition coil leading to damage of the ignition coil assembly.

To safeguard the ignition coil, several aspects should be noted when driving: prevent the ignition coil from being exposed to heat or moisture; do not turn on the ignition switch when the engine is not running; regularly check, clean, and tighten the wire connectors to avoid short-circuits or grounding; control engine performance to prevent high voltage; the spark plug must not “hang fire” for a long time; moisture on the ignition coil should only be wiped off with a cloth, never dried by fire, as this could damage the ignition coil.
