車のイグニッションコイルはどのくらいの頻度で交換する必要がありますか?

車の多くの部品の中で, many play a key role, but they are prone to damage due to the impact of their working environment. For instance, spark plugs and ignition coils. These important parts, if found abnormal during use, must be carefully checked and not overlooked. Many people say that there’s no need to worry about the lifespan of the ignition coil; it’s not expensive, just replace it when it breaks. だから, how often should the ignition coil be replaced in general? Actually, there is no fixed replacement cycle for the ignition coil.

Everyone knows that spark plugs need to be replaced regularly, but many people neglect the maintenance of other components in the ignition system, such as the high-voltage ignition coil. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition coil. Because it works in a high-temperature, dusty, and vibrating environment for a long time, it will inevitably age or even break.

Simply put, the ignition coil is the part that allows the spark plug to “generate sparks” and ignite the mixed gas in the cylinder. It is actually responsible for transforming the vehicle’s low-voltage current into high-voltage current, a transformer. 通常の状況では, each cylinder has a set of ignition coils and spark plugs, and the ignition coil generally replaces every 100,000 キロメートルまたはそれ以上.

しかし, the ignition coil should not be underestimated during routine times. If anything unusual occurs, it must be treated seriously. The damage to the ignition coil is relatively easy to judge; if the vehicle suddenly experiences abnormal judder in the engine while driving (after long kilometers), accompanied by a significant lack of power, then it might be an issue with the ignition coil. Once the ignition coil becomes abnormal, the spark plug will stop working, and the mixed gas in the cylinder will not combust. The loss of power is natural when the vehicle loses a cylinder.
