What Are the Symptoms of a Broken Ignition Coil?

Once the ignition coil is abnormal, the spark plug will not work, and the mixed gas in this cylinder will not deflagrate. If the vehicle loses one cylinder, the lack of power is normal. Ignition Coil supplier shares this article for you.

Generally, when the ignition coil is seriously aging, there will be a lack of cylinders and an alarm will be accompanied by engine failure.

Those cases where there is a failure but the car does not call the police maybe because the failure is not too serious. Once this situation is in a state of rapid acceleration, it is easy to detect.

The previous car only had one ignition coil, which ignites each cylinder through the distributor. If the ignition coil is broken, it will not be able to drive.

Now every car has an ignition coil for every cylinder, and one can run without a cylinder.

For car owners, if you want to make the ignition coil life longer, you must pay attention to the use of spark plugs. Using aging spark plugs will increase its workload. In addition, you must pay attention to the water temperature of the car. The ignition coil of the car with high water temperature is easy to burn out.

In fact, the damage of the ignition coil is easier to judge. When the vehicle is driving, the engine suddenly jitters abnormally (after driving a long kilometer), accompanied by obvious lack of power, then you have to consider the possibility of ignition There is a problem with the coil.

1

In the idling state, the body shakes obviously. Observing the outlet of the exhaust pipe, the exhaust gas flow from the car has obvious intermittent. At the same time, the exhaust pipe vibrates greatly, and the "sudging" sound can be clearly heard.

2

In the course of driving, when the speed is below 2500 rpm, the body shakes obviously and acceleration is weak; when the speed exceeds 2500 rpm, the feeling of shaking disappears.

3

Open the engine cover, observe the running engine, and find that the engine shakes obviously. This kind of jitter is obviously not the jitter under normal engine working conditions, and the jitter is very large.

4

If only one ignition coil fails, the remaining three cylinders work normally, and emergency driving is not a problem, but it is very unfavorable to the car's engine, base and connecting parts. Professional auto repairers will advise the owner to temporarily stop using the cylinder lacking vehicle. If the ignition coil of more than 1 cylinder is burned, it is recommended to stop driving immediately.

How long is the life of a car ignition coil?

The function of the ignition coil is to allow the spark plug to "generate a spark" to ignite the part of the mixed gas in the cylinder. 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 coil and spark plug. The service life of the ignition coil is generally 100,000 kilometers or more.
