Ignition Coil

Ignition Coil

An auto ignition coil is an essential part of an engine's ignition system. It transforms the low voltage of the battery into a high voltage, allowing the spark plugs to ignite the gasoline-air mixture in the engine's cylinders. The automotive ignition coil consists of two terminals and a high voltage secondary winding which is wrapped around a metal core. As one of the best china ignition coil manufacturers, we provide our customer ignition coil parts with appropriate car ignition coil price. The primary winding is connected to the battery, and the secondary winding is connected to the spark plugs. When the battery is switched on, the primary winding receives a low voltage which is then transformed into a high voltage in the secondary winding, creating the spark that ignites the fuel.

How To Diagnose and Test An Ignition Coil?

Common faults

Common faults of ignition coil mainly include damage due to external force and burning due to excessive current. If the ignition coil is damaged, the ignition system will not work and the engine will not land.

Check the appearance

Check whether the appearance and shell of the ignition coil are in good condition and the model is consistent; Whether there is crack or insulation overflow, and whether the connection of each terminal is firm.

Use a multimeter

Use a multimeter to measure the resistance of the ignition coil, which should conform to the technical standards, otherwise it indicates that there is a fault and it should be replaced.

What Are The Symptoms Of A Failing Ignition Coil?

The most common symptoms of a failing ignition coil include engine misfires, trouble starting, a decrease in power, a decrease in fuel efficiency, and a rough idle. Other symptoms may include backfiring, a check engine light, and a burning smell. If the ignition coil fails completely, the engine may not start at all. If you notice any of these symptoms, it is important to have the issue inspected and repaired as soon as possible. 

Ignition coils are responsible for providing the spark that ignites the air-fuel mixture in the combustion chamber. They achieve this by converting the low-voltage current from the battery into a high-voltage current. If the ignition coil is malfunctioning, the spark may not be strong enough to ignite the mixture, leading to the aforementioned symptoms. If you think your car has a failing ignition coil, it is important to have it inspected and repaired by a reputable mechanic. Ignition coils are a crucial part of the engine and should not be overlooked.

How Long Do Ignition Coils Last?

Ignition coils typically last between 60,000 and 100,000 miles before they need to be replaced. The exact lifespan of an ignition coil will depend on a variety of factors, such as the type of car, the quality of the ignition coil, and the driving habits of the driver.

Poor driving habits, such as excessive idling, revving the engine, or driving in extreme temperatures, can all cause a decrease in the life of an ignition coil. Similarly, using a low-quality ignition coil or one that does not fit the car properly can lead to a shorter lifespan as well.

It is important to ensure that the ignition coils are regularly checked for maintenance and replaced when necessary. If the vehicle begins to experience starting issues, misfiring, or loss of power, these are all signs that the ignition coils may be nearing the end of their lifespan.

In general, ignition coils should be replaced every 60,000 to 100,000 miles. If the vehicle is being driven in extreme conditions or is driven more aggressively, the coils may need to be replaced even sooner. Ignition coils are essential components of a vehicle and should be replaced at the first sign of failure to avoid any major problems.
