1. A method of operating an internal combustion engine having at least two cylinders, said method comprising:

  • acquiring a cylinder-specific first cylinder signal from each of the at least two cylinders via a sensor; and

    controlling a combustion parameter of each of the at least two cylinders as a function of the respective cylinder-specific first cylinder signal using a control device;

    wherein said controlling comprises setting a cylinder-specific reference cylinder value for the cylinder-specific first cylinder signal for each of the at least two cylinders via the control device such that at least one of NOx emissions and combustion efficiency of the at least two cylinders is identical or similar, and using the control device to adjust the combustion parameter of each of the at least two cylinders as a function of a deviation of the respective cylinder-specific first cylinder signal from a corresponding cylinder-specific reference cylinder value such that the respective cylinder-specific first cylinder signal tracks the corresponding cylinder-specific reference cylinder value.
