What Are The Manifestations 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 during operation, and symptoms such as acceleration and weakness will also follow.

　　Increase in fuel consumption and decrease in power: With the weakening of the spark plug's ability to jump over, the combustion of the engine's combustible mixture will be affected, resulting in increased fuel consumption and decreased power.

　　A large number of carbon deposits are produced: The weakening of the spark plug's ability to spark off will cause incomplete combustion of combustible mixtures, and incomplete combustion of combustible mixtures will produce a kind of coking substance called carbon deposits. At the same time, automobile exhaust pipes will also cause incomplete combustion. Black smoke.
