This dual spark ignition coil is designed for low-cost applications in 4-cylinder engines. The advantage of this coil is that the ECU needs only two internal power stage for supplying a 4-cylinder engine.

During the current feed on the primary side of the coil, energy is stored in the magnetic circuit. A quick turn off of the primary supply occurs a reloading on the secondary side. There the stored energy at the spark plug is reduced in the form of a high voltage spark. The spark ignites the fuel-air-ratio.
