Ignition coil classification

     Ignition coils can be divided into closed magnetic circuit coils and open magnetic circuit coils according to the magnetic circuit. Open magnetic circuit coils are generally suitable for written test ignition coils.

    Ignition coils can be divided into individual ignition and group ignition according to the ignition mode, which is understood as coil single high voltage output and double high voltage output (four high voltage outputs), for example: DG3117X https://www.donenfty.com/ignition-coil/dfsk-ignition-coil/dfsk-330-350-580-ignition-coil-28244734.html  , DQG3101B https://www.donenfty.com/ignition-coil/audi-ignition-coil/ignition-coil-for-audi-a4l-a5-a6-a7-a8l-q5.html are single high voltage output type.DG3470 is the four high voltage output type. https://www.donenfty.com/ignition-coil/changan-ignition-coil/19005270-9003848.html. DQG3128M is a dual high voltage output type .https://www.donenfty.com/ignition-coil/changan-ignition-coil/suzuki-liana-sx4-grand-vitara-ignition-coil.html.

   The work of the coil is completely controlled by the ignition coil drive circuit system integrated in the engine electronic control module ECU. The ECU realizes the orderly control of the ignition sequence of the coils through its circuit structure design, and at the same time can provide four cylinders of the engine at the appropriate time. An ignition voltage that provides the proper ignition energy.
