ABSTRACT:
A device for ignition control in a cylinder of an internal combustion engine includes an ignition coil which has a connected primary winding and a secondary winding, which is connected to a spark plug. The device also includes an ignition control unit, which connects the primary winding by way of a first line and is connected to the secondary winding by way of a second line. The second line supplies an ionic current signal emitted from the spark plug to the ignition control unit. A single line is used as the first line and the second line. The active direction of the line can be adjusted by different levels of voltage applied to the line.
