Abstract (en)
[origin: WO2022073767A1] The invention relates to a method (200) for operating an internal combustion engine (110), comprising providing and combusting an air-fuel mixture of a first composition, determining (210) a current composition of a combustion exhaust gas produced during the combustion, determining (220) an emission collective, which comprises a total amount emitted over a predefined interval for at least one component of the combustion exhaust gas, from multiple successively determined current compositions of the combustion exhaust gas, and setting (250) a second composition of the air-fuel mixture depending on the emission collective determined. The invention also relates to a computing unit and a computer program product for carrying out such a method.
