Here's a breakdown of how it works:
* Function: The coil pack acts as a transformer, stepping up the low voltage from the car's battery to a much higher voltage, typically around 20,000 volts. This high voltage is then sent to the spark plugs, creating a spark that ignites the fuel.
* Components: A coil pack consists of multiple individual coils, usually one for each cylinder in the engine. Each coil has a primary winding and a secondary winding, separated by an iron core.
* Operation: When the ignition system sends a signal to the coil, the primary winding creates a magnetic field. This field collapses when the signal is stopped, inducing a high voltage in the secondary winding. This high voltage is then directed to the spark plug through a spark plug wire.
* Benefits: Coil packs offer several advantages over older distributor-based ignition systems, including:
* Improved performance: Coil packs deliver a more powerful and consistent spark, leading to better combustion and increased power output.
* Reliability: Coil packs are less prone to wear and tear than distributors, making them more reliable.
* Easier maintenance: Individual coils can be replaced easily, reducing the need for complex repairs.
In short, a coil pack is a crucial component in a car's ignition system that transforms low voltage into high voltage to ignite the fuel, ensuring the engine runs smoothly and efficiently.
