What Does A Car Ignition Coil Do And Why Is It Important?
The car ignition coil is a vital component of the ignition system, responsible for converting the battery’s low voltage into the high voltage needed to ignite the fuel-air mixture in the engine. Without it, the spark plugs cannot function, and the engine would fail to start or run properly. Modern vehicles may use a single coil, a coil pack, or coil-on-plug systems. Regardless of the configuration, the ignition coil ensures efficient combustion and smooth engine performance, making it crucial to overall vehicle operation. How Does A Car Ignition Coil Work? Voltage Amplification The coil transforms the 12-volt current from the car battery into a much higher voltage—often up to 40,000 volts. This high voltage is essential for generating a strong spark across the spark plug gap. Energy Storage and Discharge The ignition coil stores energy briefly in a magnetic field and then releases it in a quick burst. This rapid discharge is timed to coincide with the engine's combustion cycle. I...
