Frequently Asked Questions About Ignition Coils

Q1: How does an ignition coil work in a vehicle’s engine?

The ignition coil is a vital component of a vehicle's ignition system, responsible for transforming electrical energy into the high-voltage sparks needed to ignite the air-fuel mixture in the engine cylinders. Here's how it works in detail:

• Power Source: The ignition coil draws low-voltage electricity (typically 12 volts) from the vehicle’s battery through the ignition switch.
• Voltage Transformation: Inside the coil, two wire windings—primary and secondary—are wrapped around an iron core. When current flows through the primary winding, it creates a magnetic field. When the current is suddenly interrupted, this collapsing magnetic field induces a very high voltage (up to 40,000–100,000 volts) in the secondary winding.
• Spark Generation: This high voltage is sent to the spark plugs via distributor systems (in older vehicles) or directly (in modern coil-on-plug designs), creating a spark that ignites the compressed fuel-air mixture in the combustion chamber.
• Engine Operation: This ignition process occurs in precise timing with the engine’s rotation, ensuring smooth and efficient combustion across all cylinders.

Without a functioning ignition coil, the engine cannot generate the necessary spark to start or run, making it a critical part of the vehicle’s operation.
