How often is the ignition coil changed?

many parts of the car, a lot of play a key role, but due to the impact of the working environment, easy to damage, such as spark plugs and ignition coils. These important parts, if there is an abnormal situation in use, must carefully check, can not despise. Many people say that the ignition coil does not care what life does not live, the bad change, not expensive. So, generally speaking, what is the life of the ignition coil?        everyone knows that spark plugs need to be replaced regularly, but many people ignore the maintenance of other components of the ignition system, such as ignition high pressure coils. When the engine is running, the ignition coil often has tens of thousands of volts of high voltage pulse current, because of its long time in high temperature, dusty, vibration environment work, inevitably will produce aging or even damage.        the simple explanation of the ignition coil is to let the spark plug be able to produce sparks and ignite the part of the mixture in the cylinder. Is responsible for the low voltage current vehicle changed into a high voltage transformer, normally each cylinder is equipped with a set of ignition coil and spark plugs, the service life of the ignition coil will generally in the 10 million kilometers or even longer.        however, the ignition coil can not be underestimated at ordinary times; if there is any abnormality, we must treat it carefully. The damage of the ignition coil is relatively easy to judge, when the vehicle is traveling in a sudden engine abnormal jitter (run long after the number of kilometers), accompanied by the obvious lack of power, then you have to consider the possible ignition coil problem. Once the ignition coil is abnormal, it will cause spark plug does not work, and then the cylinder will not deflagration gas mixture, the loss of a cylinder in the case, the lack of power is natural.        for the owners, to make the ignition coil longer life, one should pay attention to the use of the spark plug, use the aging spark plug will increase the workload, also pay attention to the car's water temperature, high temperature of the car ignition coil easily burnt. The reason why the low voltage on the car into high voltage is due to the same form as the ordinary transformer, the primary coil and secondary coil turns larger than. But the work is different with ordinary transformer, the ordinary transformer is working continuously, and the ignition coil is intermittent work, according to the different engine speed in different frequency of repeated energy storage and release.        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 joints, avoiding the short circuit or ground; control of engine performance, prevent excessive voltage; the spark plug shall not be long "on fire"; the ignition coil water can dry cloth, no fire baking, otherwise it will damage the ignition coil.        above the introduction of ignition coil life, just to give you a reference, in peacetime driving, or should pay more attention to. In particular, for some novice, to develop a good driving habits is very necessary, regular maintenance of car, but also less.
