Types of Ignition Coils

An ignition coil is an electrical transformer that converts battery voltage into a higher voltage, usually between 12,000 and 45,000 volts. The coil has two sets of windings, the primary and secondary, which act like inductors. When the current through the primary winding changes, it induces a current change in the secondary winding, allowing for the voltage increase.

The best ignition coils come in different types, including:

  • Ignition Coil on Plug (COP)

    Individual coils are mounted directly on top of each spark plug. Each coil converts the low voltage from the battery into the high voltage needed to ignite the air-fuel mixture in the combustion chamber. COP coils provide precise timing and consistent spark quality. They also improve engine performance and reduce emissions.

  • Wound Ignition Coil

    The wound ignition coil is one of the oldest types of ignition coils. It's also called a conventional ignition coil. The primary and secondary windings of this coil are wound around a magnetic core. The coils generate a high-voltage pulse when the circuit is opened, allowing for a spark to ignite the fuel-air mixture in the combustion chamber.

  • Distributor Ignition Coil

    This type of coil uses a distributor to route the high-voltage current to the correct spark plug. The ignition coil receives a low voltage signal from the ignition switch, creating a magnetic field in the coil. When the ignition switch is turned on, the distributor rotor spins, interrupting the magnetic field and generating a high voltage that travels through the distributor cap to the spark plugs.

  • Dual-Spark Ignition Coil

    The dual-spark ignition coil has two sets of primary and secondary windings, allowing it to power two spark plugs simultaneously. This coil is commonly used in high-performance engines that require more power and efficiency.

  • Flat Ignition Coil

    Flat ignition coils, also known as pancake coils, have a compact and low-profile design. Their primary and secondary windings are arranged in a flat, circular shape. Flat coils are often used in applications with space limitations or where a low-profile ignition system is required.

  • Hall Effect Ignition Coil

    The Hall effect ignition coil uses a Hall effect sensor to detect the position of the crankshaft or camshaft. This information is used to precisely control the timing of the spark, ensuring optimal combustion and improved engine performance. These coils are commonly used in modern engines with electronic ignition systems.

Specification & Maintenance of Best Ignition Coil

Here are some things to look out for when maintaining ignition coils:

  • Engine performance: When there is a dip in the engine's performance, it could be a sign that the ignition coil is faulty. The car may have a hard time starting, misfire, or run unevenly. This is caused when the ignition coil is unable to generate enough power to spark the fuel and air mix. Dealers and car owners can run a coil-on-plug test to ascertain the condition of the ignition coil.
  • Check engine light: A lit-up check engine light is a telltale sign that something is wrong with the vehicle. It could be anything from a minor issue to a major one. To find out what is wrong, take the car to a mechanic who will run a diagnostic test. The report will give more information on what is wrong.
  • Visual inspection: Mechanics will visually check the ignition coils for wear and tear. They will look out for cracks, carbon tracks, and terminal corrosion. They will also inspect the coil boots and high-tension wires for damage.
  • Coils with 100,000 miles on them: Coils that have been in use for a long time are bound to wear out. It is advisable to replace them after 100,000 miles. This helps to prevent ignition problems in the vehicle.
  • Fuel consumption: A faulty ignition coil can cause the car to consume more fuel than normal. This is because the fuel and air mix is not ignited properly, causing the engine to work harder. This can lead to emissions being generated. The emissions can clog the catalytic converter, which can damage it over time. This is dangerous because it contributes to global warming.

Below are maintenance tips for the ignition coil:

  • Regular tune-ups: It is important to have routine maintenance done on the vehicle. A qualified mechanic will inspect every part of the vehicle, including the ignition coils, to ensure they are in good working condition.
  • Replace spark plugs on time: Dealers should replace the spark plugs when the vehicle tells them to. Worn-out spark plugs can cause the ignition coil to work twice as hard. This can lead to an early ignition coil failure.
  • Avoid short trips: Coils are prone to wear and tear due to frequent stop-and-go traffic. This is because the engine does not reach its optimal operating temperature.
  • Use quality parts: It is best to use genuine ignition coils and other parts in the vehicle. They may be a bit expensive, but they are of great quality and will last a long time. This will save money in the long run.

How to Choose the Best Ignition Coil

Choosing the best ignition coil is an essential part of a business's car maintenance. Here are factors to consider when choosing an ignition coil.

  • Compatibility

    Ensure the ignition coil is compatible with the vehicle's make, model, and year of production. This ensures optimal performance and prevents issues.

  • Quality and Reliability

    Invest in high-quality ignition coils from reputable suppliers. These coils are reliable and have a durable and consistent spark generation.

  • Consider Engine Type

    Choose the engine type when selecting the ignition coil. For instance, high-performance coils are suitable for internal combustion engines.

  • Budget

    Set a budget that considers the long-term benefits of quality ignition coils. Avoid cheap coils because they are unreliable and have a short lifespan.

  • Warranty and Support

    Select ignition coils with a warranty period. The warranty shows confidence in the product's quality. Also, consider the availability of customer support.

  • Reviews and Recommendations

    Check online reviews and ask for recommendations from mechanics and other car owners. This provides insight into the coil's performance and reliability.

How to DIY and replace the best ignition coil

Replacing an ignition coil is a relatively straightforward process that can be performed with basic mechanical skills. However, it's important to consult the vehicle's service manual for specific instructions and torque specifications. Here's a step-by-step guide on how to replace a Best ignition coil:

  • Gather necessary tools: Socket set, ratchet, torque wrench, pliers, and a small flathead screwdriver. New ignition coils, and possibly new spark plugs (depending on their condition).
  • Disconnect the battery: Disconnect the negative (-) battery cable to prevent any electrical shorts or accidents.
  • Remove engine cover (if applicable): Some vehicles have a plastic engine cover that needs to be removed to access the ignition coils.
  • Locate the ignition coils: In most vehicles, the ignition coils are located on top of or beside the engine, near the spark plugs. The number of coils will depend on the engine configuration (one coil per cylinder in most modern cars).
  • Disconnect the electrical connectors: Each ignition coil has an electrical connector. Press the tab and pull the connector off the coil.
  • Remove the ignition coils: In some cases, the coils are held down by bolts. Use a socket and ratchet to remove the bolts and lift the coils off the engine. In other designs, the coils are simply pulled off the spark plugs, and no bolts are required.
  • Inspect and replace spark plugs (if necessary): If the spark plugs are worn out or have high mileage, it's a good idea to replace them. Refer to the service manual for the correct spark plug type and gap specifications.
  • Install the new ignition coils: If the coils are separate from the spark plugs, apply a small amount of dielectric grease inside the boot of the new coils (optional but recommended). Then, carefully press the new coils onto the spark plugs or the engine block (depending on the design). Ensure they seat properly.
  • Reconnect the electrical connectors: Push the ignition coil connectors onto their respective coils, ensuring they click into place.
  • Reinstall any bolts or fasteners: If the coils were held down with bolts, use a torque wrench to tighten them to the manufacturer's specifications.
  • Reconnect the battery: Reconnect the negative (-) battery cable, ensuring a secure connection.
  • Start the engine: Turn the key to the "on" position without starting the engine to ensure all electrical connections are good. Then, start the engine and listen for any unusual noises or issues. If everything sounds normal, replace the engine cover (if applicable).
