Ignition coil

Types of Ignition Coil

An ignition coil is an important part of the car's ignition system. It is a transformer that converts low battery voltage into high voltage, which is enough to create a spark across the spark plug's electrode. This spark causes the air-fuel mixture to ignite, making the engine run. Ignition coils come in different types, depending on the vehicle make and model. Below are the various types of ignition coils:

• Ignition Coil Pack

  This ignition coil is often used in modern cars. It has several coils packed together, with each coil serving one spark plug. The coils communicate with the engine control unit, which controls the ignition timing. This ensures that each spark plug fires at the right time. It also helps to improve engine performance and reduce emissions.

• Individual Ignition Coils

  Some high-performance and luxury vehicles use individual ignition coils for every spark plug. This ignition coil type improves combustion, reduces emissions, and increases engine power. It is also more efficient because each coil only has to ignite one spark plug.

• Double Spark Ignition Coils

  Some vehicles, especially those in Asia, use double spark ignition coils. This type of coil has one coil for every two spark plugs. The coil generates enough spark for both spark plugs. This helps to reduce the ignition system's cost while improving fuel efficiency. However, the engine performance may not be as good as that of individual ignition coils.

• Distributor Ignition Coil

  This is the oldest type of ignition coil. It is used in most vehicles made before 1990. The coil works with a distributor to send the high-voltage spark to the correct spark plug. The coil has a single transformer that supplies all the spark plugs. The distributor controls which spark plug will receive the spark. However, this system is less efficient and has more moving parts that can wear out.

• Carbon Ignition Coil

  This is a type of ignition coil that uses carbon brushes to make contact with the ignition system. The carbon brushes help to reduce wear and tear, making the coil last longer. Carbon ignition coils are often used in older vehicles or in budget-friendly modern cars.

• Magnetic Ignition Coil

  This ignition coil uses magnets to generate high voltage. The magnetic ignition coil is very efficient and can create a strong spark. It is often used in high-performance vehicles or in racing cars, where engine performance is critical.

Specification & Maintenance of Ignition Coils

Before purchasing ignition coils, it is vital to understand their specifications so that the perfect coils for the intended use are selected. Below are some of the factors to consider:
