    • The invention relates to a method for generating an ion current which occurs as a direct current between a central electrode and one or more side electrodes of a spark plug of a spark ignition engine which is supplied repeatedly with an ignition voltage from an ignition voltage source, wherein the spark ignition engine is assigned an engine control unit, which, in an engine cycle, determines for each spark plug a target ignition point and/or an activation point for the ignition voltage source before the target ignition point, and a second voltage source is provided, which delivers a second voltage for the generation of the ion current, wherein the second voltage source lying in the engine cycle for a first time interval Δt1, which is shorter than the duration of the engine cycle, is connected to the electrodes of the spark plug, and wherein the ion current flowing as a result of the application of the second voltage to the electrodes of the spark plug takes a path which avoids the ignition voltage source.

    • A battery, an energy charge inductance, and a first transistor are connected in series in an ignition system. A primary winding and a second switching device are connected in series between the ground and a point between the energy charge inductance and the first switching device. A drive circuit switches periodically on and off the first switching device and the second switching device during multispark duration of the spark plug such that each switching device has a different switching status from each other. After the multispark duration, the drive circuit switches periodically on and off the second transistor with a short switching interval. The switching interval is set such that a relatively low voltage that almost causes a spark is impressed to the spark plug. An ion current detection is implemented by using this voltage as a power source.
