Ignition coil function
       The ignition coil turns the low-voltage DC of the battery into  high-voltage electricity, which generates sparks through the  spark plug, ignites the mixture in the cylinder, and when the  grounding channel of the primary group is connected, the  cover is initially charged. Once the controller cuts off the  primary winding circuit, the charge is aborted. A high voltage  is induced in the winding of this stage, which causes the  spark plug to discharge
How long to replace the ignition coil is reasonable
1,high-voltage line breakdown
2,Breakdown between high and low voltage coil, creepage
3,Creepage between high voltage coil and iron core
4,Poor sealing, resulting in a long time to work with sealing glue (epoxy) cracking phenomenon
 
       We recommend replacing the ignition coil once every 60,000 km.  When the engine vomits, Jitter, accelerates weakly or the engine  fault light turns on, it is recommended to check the spark plug  and ignition coil for regular maintenance of the ignition coil:  the main check is whether the ignition coil insulation cover or  Shell is broken? Are there any ablation marks on the high  voltage output terminal? Is The rubber rod broken? Are there  any burn marks on the rubber rod? Such as the appearance of  Shell cracking, high-pressure end ablation marks, rubber rod  cracking, rubber rod ablation marks. It is recommended to  replace the ignition coil, causing the coil to climb the internal  power
