In general, what is the lifespan of an ignition coil?
Under normal circumstances, each cylinder is equipped with a set of ignition coils and spark plugs. The service life of automobile ignition coils is generally 100,000 kilometers or even longer.
For car owners, if they want the ignition coil to last longer, on the one hand, they should pay attention to the use of spark plugs. The use of aging spark plugs will increase their workload. In addition, they should pay attention to the water temperature of the car. The ignition coil of cars with high water temperature is easy to burn out.
The reason why the low-voltage electricity on the car can be turned into a high voltage is that it has the same form as the ordinary transformer, and the ratio of the number of turns of the primary coil to the secondary coil is large. But the working method is different from ordinary transformers. Ordinary transformers work continuously, while ignition coils work intermittently. It repeatedly stores and discharges energy at different frequencies according to different engine speeds.
The failure of the ignition coil of the car is often due to the poor quality of the fuel and the insufficient combustion of the fuel, resulting in excessive carbon deposits in the spark plug, and the ignition coil will be broken down, resulting in damage to the ignition coil assembly.
Based on the protection of the ignition coil, you need to pay attention to the following aspects when driving: prevent the ignition coil from being heated or damp; Engine performance, prevent the voltage from being too high; the spark plug must not be "hanging the fire" for a long time; the moisture on the ignition coil can only be wiped dry with a cloth, and it must not be baked with fire, otherwise the ignition coil will be damaged.
Among the many parts of a car, many play a key role, but are easily damaged due to the influence of the working environment, such as spark plugs and ignition coils. These important parts, if there are abnormal conditions during use, they must be carefully checked and cannot be underestimated. So how long does it take to replace the car ignition coil?
We think the replacement cycle still depends on the car owner. The ignition coil is a consumable that needs to be replaced in time, just like the spark plug. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition wire. Because it works in a high-temperature, dusty, and vibrating environment for a long time, aging or even damage will inevitably occur.
The aging and damage of the ignition wire will greatly reduce the ignition energy, increase the fuel consumption of the engine, reduce the power, and seriously cause misfire, which is a fatal failure for the engine with the three-way catalytic converter.
It is not necessary to replace the ignition coil of the car with the spark plug at the same time. The spark plug should be replaced every 30,000 kilometers or so, and the ignition coil can be replaced every 100,000 kilometers without damage.
