Everyone knows that spark plugs must be replaced regularly, but many people ignore the maintenance of other parts of the ignition system, such as ignition high-voltage coils. When the engine is running, the ignition coil is often tens of thousands of volts of high voltage pulse current. Because it works in a high temperature, dusty, and vibrating environment for a long time, it inevitably produces aging and even damage.
The simple explanation for the ignition coil is to allow the spark plug to "spark" and ignite the part of the cylinder mixed gas. 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 coil is generally replaced at 100,000 kilometers or more.
However, the ignition coil can not be underestimated at ordinary times. If anything is unusual, you must treat it carefully. The damage to the ignition coil is easier to judge. When the vehicle suddenly has an abnormal shaking of the engine during driving(after a long number of kilometers), accompanied by a clear lack of power, you must consider the possibility that it may be the ignition coil. The problem. If there is an anomaly in the ignition coil, the spark plug will not work, and then the mixed gas of this cylinder will not explode. When the vehicle loses one cylinder, the lack of power is natural.
In general, what is the life of the ignition coil?
Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs, and the ignition coil's service life is generally 100,000 kilometers or more.
For the owner, he wants to make the ignition coil live longer. On the one hand, he must pay attention to the use of spark plugs. The use of aging spark plugs will increase his workload. In addition, he must pay attention to the water temperature of the car. The high water temperature of the ignition coil is easily burned. The reason why it is possible to turn the low piezoelectric vehicle into Gaodianya is due to the same form as the ordinary Transformer, and the ratio of the primary coil to the secondary coil is large. However, the working method is different from that of ordinary Transformers. Ordinary Transformers work continuously, while ignition coils work intermittently. They repeatedly store energy and release energy at different frequencies according to the engine's different speeds.
The failure of the ignition coil is often due to the poor quality of the fuel, and the fuel can not be fully burned, resulting in too much carbon accumulation of the spark plug, and the ignition coil will be broken and the ignition coil assembly will be damaged.
Based on the protection of the ignition coil, the following aspects need to be paid attention to when driving: preventing the ignition coil from being heated or damp; Do not turn on the ignition switch when the engine is not running; Check, clean and tighten the connections regularly to avoid short-circuit or iron; Control engine performance to prevent excessive voltage; The spark plug can not be "suspended" for a long time; The moisture on the ignition coil can only be dried with cloth and must not be baked with fire, otherwise it will damage the ignition coil.
