Abstract

A multi-ignition coil control system includes a spark plug including first and second center electrodes, and first and second ground electrodes spaced apart from the center electrodes by a predetermined distance, a first ignition coil including a primary coil, and a secondary coil in which a discharge current is generated by electromagnetic induction with the primary coil, and a second ignition coil including a primary coil, and a secondary coil in which a discharge current is generated by electromagnetic induction with the primary coil, wherein one end of the secondary coil of the first ignition coil and one end of the secondary coil of the second ignition coil are electrically connected to one of the center electrodes, and the other end of the secondary coil of the first ignition coil and the other end of the secondary coil of the second ignition coil are electrically connected to the other of the center electrodes.
