Abstract

A method and a device for controlling a combustion of an internal combustion engine are provided, including an arrangement, which generates a signal for the intensity of the combustion in a combustion chamber of the internal combustion engine from a sensor signal of the internal combustion engine. The intensity is compared to a reference level, which was formed from intensities of preceding combustions in the combustion chamber by moving average calculation. An irregular combustion is detected if the intensity exceeds the reference level in a predetermined manner, and then at least one operating parameter of the internal combustion engine is shifted in the direction of an avoidance of the irregular combustion. Following an irregular combustion, the averaging for forming the reference level is accelerated for a specified duration.
