Abstract

A method for operating an internal combustion engine, in particular a gas engine, having at least three cylinders, wherein a cylinder-specific signal (pmax, E) is acquired from each of the at least three cylinders, wherein a reference value (pmedian, Emedian) is generated from the cylinder-specific signals (pmax, E), wherein at least one combustion parameter (Q, Z) of one of the at least three cylinders is controlled as a function of a deviation of the cylinder-specific signal of the one of the at least three cylinders (pmax, E) from the reference value (pmedian, Emedian), whereupon the cylinder-specific signal of the one of the at least three cylinders (pmax, E) follows the reference value (pmedian, Emedian), wherein a median of the cylinder-specific signals (pmax, E) is generated as the reference value (pmedian, Emedian).
