1. The main reasons for the damage of the automotive ignition coil are:
In the car, the automotive ignition coil acts like a transformer, which instantly converts a 12-volt voltage into a voltage of 20,000 to 30,000 volts. The car needs such a large voltage to run normally. There is a problem with the automotive ignition coil. It may be that the plastic casing of the coil is broken or the copper wire inside is broken. This is related to the driving situation. Some cars have not broken for many years while others have broken down in a few years. For car owners, if you want to use the automotive ignition coil for a long time, you must pay attention to the use of spark plugs. Using aging spark plugs will increase the workload of the automotive ignition coil. In addition, pay attention to the water temperature of the car. Easy to burn out.
2. The relationship between automotive ignition coil and fuel consumption:
When the automotive ignition coil is damaged, the ignition voltage is too low or the spark is too weak, and the lack of fire will result in insufficient combustion of the mixed gas in the engine. The oxygen sensor in the exhaust pipe will detect the oxygen content and send the information It is fed back to UCE, and UCE corrects the fuel injection amount according to the number provided by the oxygen sensor (total fuel injection = basic fuel injection + fuel injection correction), which will extend the fuel injection time of the injector and increase fuel consumption. This leads to increased fuel consumption. Therefore, when the automotive ignition coil is damaged, it will increase fuel consumption.
It is recommended that car owners choose reliable products as much as possible when choosing an automotive ignition coil, which can reduce fuel consumption, improve gasoline combustion, and reduce environmental pollution.
3. How long is it reasonable to replace the automotive ignition coil?
There is no authoritative statement on this issue on the Internet. Some say "change once for 60,000 kilometers", and some say "change once for 90-100,000 kilometers."
During driving, if the engine does not vomit, shake, or accelerate weakly, the automotive ignition coil can be maintained regularly:
is mainly to check whether the insulating cover or casing of the automotive ignition coil is broken? Are there any signs of ablation on the high-voltage output terminal? Are there any cracks in the rubber rod? Are there any signs of ablation on the rubber rod?
If there are shell cracks, high-pressure end ablation marks, rubber rod rupture, rubber rod ablation marks. Then replace the automotive ignition coil.
And when choosing an automotive ignition coil, you should choose a high-quality and reliable automotive ignition coil. If you choose a fake product, it may cause serious consequences.
