As the most core component of the engine ignition system, the ignition coil is mainly responsible for intermittently converting low-voltage electricity into high-voltage electricity. And if there is no ignition coil to convert high-voltage electricity, then the combustible gas mixture in the cylinder will not be ignited by breakdown, so the engine will not work normally.
It can be seen that the ignition coil plays an important role in the system of various parts of the engine, so with long-term use, what will the ignition coil behave when it ages? How many to replace the ignition coil at a time?
The performance of ignition coil aging
The symptom of the aging of the engine ignition coil is the decline of the ability to convert low-voltage electricity into high-voltage electricity, which is mainly reflected in the weakening of the sparkover ability on the spark plug.
The specific performance is as follows
Engine jitter:The engine will jitter intermittently while it is working, and symptoms such as acceleration and weakness will also follow.
Increase in fuel consumption and decrease in power:As the spark-over ability of the spark plug weakens, the combustion of the engine's combustible gas mixture will be affected, resulting in adverse reactions such as increased fuel consumption and decreased power.
A large amount of carbon deposits are produced:The weakening of the spark plug's ability to spark will cause the incomplete combustion of the combustible mixture, and the incomplete combustion of the combustible mixture will produce a kind of coking substance called carbon deposit, and the car exhaust pipe will also emit black smoke.
How often do I change the ignition coil?
In fact, the service life of the ignition coil is longer than our phenomenon. Under normal circumstances, a replacement of 10-14 km is considered a normal frequency.
