used ignition coil

Types of Used Ignition Coil

Used ignition coils are categorized based on the number of cylinders in an engine. For instance, if an engine has four cylinders, it will require four ignition coils. The ignition coil is responsible for converting low battery voltage into high voltage to generate an electric spark in the combustion chamber. Below are the different types of used ignition coils:

• Used Ignition Coil Pack

  This type of ignition coil is also referred to as a waste spark coil. It is commonly used in vehicles with V6 and V8 engines. Unlike other types of ignition coils, ignition coil packs do not have a central electrode. They are made up of two or three individual coils that are connected together.

• Used Single Ignition Coil

  This type of ignition coil is used in older models of cars that have engines with four-cylinder. In this type of ignition coil, one ignition coil is connected to each cylinder in the engine. The ignition coil receives low voltage power from the battery and converts it into high voltage to create a spark in the combustion chamber.

• Used Dual-Output Ignition Coil

  This type of ignition coil is used in vehicles that have six-cylinder engines. The dual-output ignition coil is a combination of the single ignition coil and the ignition coil pack. It consists of one ignition coil that is divided into two sections to serve two cylinders. The coil generates sparks for both cylinders at the same time.

Specification and maintenance of used ignition coil

• Voltage output

  The primary and secondary windings of the used ignition coils generate a voltage difference. The primary winding has a low resistance of 0.4 to 2 ohms and receives the battery's 12-volt current. The secondary winding, however, has a high resistance of 8000 to 30,000 ohms. It is 4000 to 15,000 times larger than the primary's low resistance. When the ignition current in the primary coil is interrupted, the secondary coil generates an 8 to 30-volt pulse and sends it to the spark plugs. The secondary coil's higher voltage is possible because it has many more loops than the primary.

• Construction materials

  Used ignition coils are constructed using different components for specific purposes. The most important part of the ignition coil is the iron core, which is wrapped with wire coils. The iron core serves to boost the electric signal. A layer of insulation is needed between the wires in the used ignition coil to protect them from short circuits. This insulation is provided by the rubber, plastic, or epoxy resin. Finally, the used ignition coil is encased in a hard plastic or metal shell to keep it safe.

• Coil type

  There are several types of used ignition coils. The most common are the used ignition coil-on-plug and the used single ignition coil. In the used coil-on-plug, the ignition coil is placed directly on top of the spark plug. This setup allows for a more precise and efficient ignition of the air-fuel mixture. The coil is connected to the distributor in the case of a used single ignition coil. This setup is more common in older car models. Other types of used ignition coils include the used dual ignition coils and the used high-output ignition coils.

Used ignition coil maintenance

Regular maintenance of the used ignition coils is essential for their longevity and optimal performance. Here are some used ignition coil maintenance tips:

• Regular inspection

  The first step in maintaining used ignition coils is to inspect them regularly. Check out for any obvious signs of wear and damage. Look out for cracks, chips, and rust that may affect the coils' performance. Remember that even minor damage can cause major problems down the road. Therefore, it is essential to inspect the coils regularly.

• Cleanliness

  Another important aspect of used ignition coil maintenance is keeping it clean. Dirt and grime can damage the coil. Therefore, wipe the coils using a damp cloth regularly. Avoid using harsh cleaning agents or high-pressure cleaners, as they can cause more damage.

• Proper connection

  Ensure that the cables and connectors of the used ignition coils are tightly fastened. Loose cables and connectors can disrupt the ignition signal and cause the engine to misfire. Check that the cables and connectors are tightly fastened at all times.

• Heat resistance

  Ignition coils are sensitive to heat. Therefore, it is important to keep the used ignition coils away from heat sources like the exhaust system. Prolonged exposure to high temperatures can damage the coils and reduce their lifespan.

• Follow manufacturer's instructions

  Different types of ignition coils have their own maintenance requirements. Therefore, it is important to follow the manufacturer's instructions. Read and understand the maintenance requirements of the specific type of used ignition coils before use.

How to Choose Used Ignition Coil

When choosing used ignition coils, there are several factors that retailers and end users of the product need to consider. These factors are necessary so that the end user can be able to select an ignition coil that is compatible with their vehicle and one that will give them a service.

The first factor to consider is the make and model of the vehicle. Find out the vehicle specifications and the ignition coils that are compatible with it. This information will help select the ignition coil that is compatible with the vehicle.

The other factor to consider is the condition of the ignition coil. Since the ignition coil is used, it is important to check it thoroughly and inspect its condition. Check for any damages, wear, or corrosion that may affect the performance of the ignition coil. Also, consider the mileage and how the previous owner maintained it.

The other factor to consider when choosing a used ignition coil is the warranty. End users and retailers should choose a used ignition coil that provides at least a limited warranty. This warranty will give the user confidence in the product's quality and also allow them to return the product in case of failure.

Finally, users can seek professional advice when choosing a used ignition coil. They can consult their mechanic or vehicle specialist to help them choose the right used ignition coil for their vehicle.
