Ignition Coil Working Principle
An ignition coil is essential in spark-ignition engines (e.g., cars), transforming low-voltage battery power (typically 12V) into high-voltage (20,000–50,000V) to spark the spark plugs and ignite the air-fuel mixture.
Step-by-Step Process
Current Flow in Primary Winding: When the ignition key is turned on, low-voltage DC current from the battery flows through the primary winding (via a switch like breaker points in older systems or an electronic control module in modern ones). This creates a strong magnetic field around the coil, which builds up and stores energy in the iron core.
Field Collapse: The current is suddenly interrupted (e.g., points open or ECU signals a transistor to cut off). The magnetic field rapidly collapses, inducing a high-voltage surge in the secondary winding due to the large number of turns (voltage ratio ≈ turns ratio, often 1:100).
High-Voltage Output: This induces a massive voltage spike in the secondary winding, which travels via high-tension leads to the distributor (in traditional systems) or directly to coil-on-plug setups in modern engines, firing the spark plug.
Spark Generation: The high voltage arcs across the spark plug gap, creating a hot spark that ignites the fuel mixture, powering the engine cycle
Modern coils (e.g., in waste-spark systems) enhance efficiency; failures cause misfires or no-start issues—test with a multimeter for diagnostics.
