How an ignition coil works？

Are you curious about how an Ignition coil works? Why is it one of the most important parts in your car?

An ignition coil is an important component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into high voltage needed to create a spark in the spark plugs. Here is how an ignition coil works:

Low Voltage Input: The ignition coil is connected to the battery of the vehicle, which provides a low voltage electrical current (typically around 12 volts).

Coil Windings: The ignition coil consists of two sets of wire windings - primary windings and secondary windings. When the low voltage current flows through the primary windings, it creates a magnetic field around the coil.

Magnetic Field Build-Up: As the current flows through the primary windings, the magnetic field within the coil intensifies.

Magnetic Field Collapse: When the current is interrupted (such as when the distributor interrupts the current flow), the magnetic field collapses rapidly. This collapse of the magnetic field induces a high voltage current in the secondary windings of the coil.

High Voltage Output: The high voltage current created in the secondary windings of the ignition coil is then sent to the distributor, which distributes the high voltage current to the spark plugs. The spark plugs use this high voltage to create a spark that ignites the air-fuel mixture in the engine's combustion chamber, starting the engine.

The ignition coil is considered one of the most important parts of a car for several reasons:

Spark Generation: The ignition coil is responsible for generating the high voltage spark needed to ignite the air-fuel mixture in the engine's combustion chamber. Without this spark, the engine will not start or run.

Engine Performance: The ignition coil plays a crucial role in ensuring proper engine performance. A faulty or failing ignition coil can result in misfires, rough idling, and overall poor engine performance.

Fuel Efficiency: A properly functioning ignition coil helps ensure efficient combustion of the air-fuel mixture in the engine. This can contribute to better fuel efficiency and lower emissions.

Overall Engine Health: The ignition coil is a key component of the ignition system, which is essential for the overall health and functionality of the engine. A failing ignition coil can lead to engine stalling, difficulty starting the vehicle, and potential damage to other engine components.

Safety: A malfunctioning ignition coil can impact the safety of the vehicle by causing engine issues while driving, such as sudden loss of power or stalling. Proper ignition coil maintenance and replacement when necessary can help prevent unexpected breakdowns and ensure safe operation of the vehicle.
