Abstract

See full text

A method for operating a combustion engine is disclosed. In an embodiment, the method includes: generating several sparks to ignite a fuel-air mixture in a combustion chamber by an ignition device of the combustion engine, determining a combustion duration of at least one of the sparks, detecting a deviation of an actual operation from a target operation of the combustion engine at least depending on the combustion duration, compensating for the deviation by implementing at least one measure which influences a combustion of the fuel-air mixture in the combustion chamber, determining the combustion duration of the chronological first of the sparks, allocating the first spark to a first spark type or to a second spark type depending on the combustion duration, and implementing the at least one measure if at least one value which characterizes a frequency of one of the spark types exceeds a threshold value.
