Abstract
In a method and a device for operating an internal combustion engine, a first variable characterizing the air-mass flow to the internal combustion engine is determined, and a second variable characterizing the air-mass flow is determined. The second variable characterizing the air-mass flow is used to derive a third variable characterizing the air-mass flow, which is delayed in time with respect to the second variable characterizing the air-mass flow. A difference is formed between the second variable characterizing the air-mass flow and the third variable characterizing the air-mass flow. The first variable characterizing the air-mass flow is corrected by the difference.
