Daily Maintenance Of Ignition Coil

　　With the improvement of living standards, cars have entered more and more people's homes, and the daily maintenance of cars has become an important thing for many car owners. In addition to the routine maintenance of the three oil filters, many car owners still lack the knowledge of inspection and maintenance of other parts. Many car owners have encountered car shakes or sudden high fuel consumption, which may be related to a part called the ignition coil on the car.

　　To enable the majority of car owners to better understand the function of the ignition coil and the knowledge of daily inspection, today we will explain to you the knowledge of the ignition coil and the methods of daily inspection and maintenance.

　　1. The main reasons for ignition coil damage are:

　　In the car, the ignition coil acts like a transformer, instantly converting the 12 volts into 20,000 to 30,000 volts. The car needs such a large voltage to run normally. There is a problem with the 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 driving usage, some cars are not broken for many years and some cars are broken for a few years. For car owners, if they want to use the ignition coil for a long time, on the one hand, they should pay attention to the use of spark plugs. The use of aging spark plugs will increase the workload of the ignition coil. In addition, they should pay attention to the water temperature of the car. The ignition coil of a car with high water temperature is easy to burn out.

　　2. The relationship between ignition coil and fuel consumption:

　　When the ignition coil is damaged, the ignition voltage is too small or the spark is too weak, and a misfire will occur, resulting in insufficient combustion of the mixed gas in the engine. The oxygen sensor in the exhaust pipe will detect the oxygen content and feedback the information For UCE, UCE corrects the fuel injection quantity according to the number provided by the oxygen sensor (total fuel injection quantity = basic fuel injection quantity + fuel injection correction quantity), which will prolong the fuel injection time of the fuel injector and increase fuel consumption. resulting in increased fuel consumption. So when the ignition coil is damaged, it will increase fuel consumption. It is suggested that when choosing an ignition coil, car owners should try their best to choose products with reliable quality, which can reduce fuel consumption, improve gasoline combustion, and reduce environmental pollution.

　　3. How often is it reasonable to replace the ignition coil?

　　There is no authoritative statement on this issue on the Internet, some say "replace every 60,000 kilometers", and some say "replace every 90,000-100,000 kilometers".

　　During driving, if there is no engine vomiting, shaking, or weak acceleration, the ignition coil can be regularly maintained:

　　Mainly to check whether the insulation cover or shell of the ignition coil is cracked. Is there any ablation mark at the high-voltage output end? Is there any crack in the rubber rod? Is there any ablation mark on the rubber rod?

　　If there are cracks in the shell, ablation marks at the high-voltage end, cracks in the rubber rod, and ablation marks in the rubber rod. Then replace the ignition coil. And when choosing an ignition coil, you should choose an ignition coil with good quality and reliable quality. If you choose a fake and inferior product, it may cause serious consequences.
