Abstract

In a method for operating an internal combustion engine, a computer program product, a computer program, and a control and/or regulation device for the internal combustion engine, the internal combustion engine is allowed to be operated using an enriched air/fuel mixture, without exceeding a rich combustion limit of the internal combustion engine. In the process, a setpoint value for a variable characterizing the air/fuel mixture is specified in at least one operating state of the internal combustion engine. A value of at least one variable characterizing the quality of combustion is determined. The determined value for the at least one variable characterizing the quality of combustion is compared to a first specified threshold value. If the determined value for the at least one variable characterizing the quality of combustion deviates from the first specified threshold value by an amount that exceeds a second specified threshold value, then the setpoint value is corrected.
