Many parts of automobiles play a key role, but due to the influence of working environment, they are easy to damage, for example, spark plugs and ignition coils. These important parts, if there are abnormal conditions in the use, must be carefully checked, can not be ignored. A lot of people say that the ignition coil does not have to pipe life life, it is bad to change, it is not expensive. So, generally speaking, how often do the ignition coils be replaced once? In fact, the ignition coil does not have a fixed replacement cycle.

It is known that the spark plugs should be replaced regularly, but many people ignore the maintenance of the other parts of the ignition system, for example, the ignition of the high pressure coil. When the engine is running, there are tens of volts of high voltage pulse current on the ignition coil. Because of its long time working in high temperature, dusty and vibrating environment, it will inevitably produce aging or even damage.

The simple explanation of the ignition coil is to allow the spark plug to "produce sparks" and to ignite the part of the mixture of gas in the cylinder. Actually, it is responsible for transforming the low voltage current of the vehicle into a high-voltage transformer. Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs, and the ignition coils will usually be changed at 100 thousand kilometers or even longer.

However, in peacetime, the ignition coil can not be ignored, if any abnormal, must be treated carefully. The damage of the ignition coil is easy to judge. When the vehicle suddenly runs abnormal jitter (after running a long distance of kilometers), and at the same time, the power is obviously missing, then you have to consider the problem of the ignition coil. Once the ignition coil is abnormal, it will cause the spark plug not to work. Then the mixture of the cylinder will not deflagrate. If the vehicle loses a cylinder, the loss of power is natural.
