Abstract (en)
The method involves detecting a cylinder-specific signal of each cylinder, such as of cylinder internal pressure, cylinder exhaust gas temperature, nitrogen oxide emissions or combustion-air ratio, and forming a set value from the signals of the cylinder. A combustion parameter of the corresponding cylinder is adjusted in dependence on the deviation of a signal from the set value. The signal is tracked to the target value, where the median of the signals is formed as the set value.

Verfahren zum Betreiben einer Brennkraftmaschine (1), insbesondere eines Gasmotors, mit wenigstens drei Zylindern (2), wobei von jedem Zylinder (2) ein zylinderindividuelles Signal (p max , E) erfasst wird, wobei aus den Signalen (p max , E) der Zylinder (2) ein Sollwert (p median , E median ) gebildet wird, wobei in Abhängigkeit von der Abweichung eines Signals (p max , E) vom Sollwert (p median , E median ) wenigstens ein Verbrennungsparameter (Q, Z) des entsprechenden Zylinders (2) eingestellt wird, wobei das Signal (p max , E) dem Sollwert (p median , E median ) nachgeführt wird, wobei als Sollwert (p median , E median ) der Median der Signale (p max , E) gebildet wird.
