Ateşleme bobininin ömrü nedir?

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

For car owners who want their ignition coils to last longer, on one hand, they should pay attention to the use of spark plugs. Using aged spark plugs will increase their workload. On the other hand, they should monitor the water temperature of the car. Cars with high water temperatures tend to burn out the ignition coils. The reason it can convert low voltage in the car into high voltage is because it has the same form as an ordinary transformer, with a higher turns ratio between the primary coil and the secondary coil. Fakat, its working mode is different from that of ordinary transformers; ordinary transformers work continuously, while ignition coils work intermittently. They store and release energy repeatedly at different frequencies according to the different speeds of the engine.

Faults in ignition coils are often due to poor fuel quality. When fuel cannot be fully burned, it leads to excessive carbon deposits on the spark plugs, which can cause the ignition coil to be pierced and damage the ignition coil assembly.

For the protection of the ignition coil, you should pay attention to the following aspects when driving: prevent the ignition coil from overheating or getting damp; do not turn on the ignition switch when the engine is not running; regularly check, clean, and tighten the circuit connectors to avoid short circuits or metal contacts; control engine performance to prevent overvoltage; do not let the spark plug “hang fire” for a long time; moisture on the ignition coil should only be wiped dry with a cloth, never baked with fire, otherwise, it will damage the ignition coil.
