What is an ignition coil?
An ignition coil is an essential component of a vehicle’s ignition system. Its primary function is to convert the battery’s low voltage into the thousands of volts required to create an electric spark in the spark plugs. This spark is necessary to ignite the air-fuel mixture in the combustion chamber, ultimately powering the engine.
The ignition coil consists of two primary windings: the primary coil and the secondary coil. The primary coil is connected to the battery and generates a magnetic field when current passes through it. This magnetic field then induces a higher voltage in the secondary coil, which is connected to the spark plugs. The secondary coil amplifies this voltage, allowing for the creation of a powerful spark.
Ignition coils often have multiple outputs, with each output connecting to a spark plug. This design allows for multiple sparks to occur simultaneously or sequentially, depending on the engine’s firing order.
Ignition coils come in different types, including conventional, coil-on-plug (COP), and distributorless ignition systems (DIS). Conventional ignition coils are typically found in older vehicles and have a single coil that serves all the spark plugs. COP systems have individual coils attached directly to the spark plugs, eliminating the need for spark plug wires. DIS systems, on the other hand, use multiple coils mounted on a single module.
Regardless of the type, the ignition coil plays a critical role in the functioning of the engine. Without a properly functioning ignition coil, the engine may experience misfires, reduced power, and even fail to start.
