Ignition Coils

Definition of Ignition Coils as it relates to Automotive, Automotive Fuel Additives, Tire RepairAutomotive

Ignition coils are an essential component in an automotive ignition system, responsible for converting the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs. This spark ignites the air-fuel mixture in the engine's cylinders, allowing the vehicle to run. Ignition coils are built with a primary and secondary winding, with a core made of iron or ferrite to focus the magnetic field. The primary winding is connected to the battery and the ignition system, while the secondary winding is connected to the spark plugs. When current flows through the primary winding, it creates a magnetic field that induces a high voltage in the secondary winding. This high voltage is then sent to the spark plugs, creating a spark that ignites the air-fuel mixture. Ignition coils come in various shapes and sizes, with some being part of the distributor while others are located separately in modern vehicles. They can fail due to wear and tear or overheating, leading to misfires, poor fuel efficiency, or difficulty starting the engine.
