摘要： 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.

摘要： A method for operating an internal combustion engine, in which at least one first influence variable influences a state variable of the air in the intake manifold. The state variable of the air in the intake manifold is ascertained while taking into account a plurality of influence variables, which influence the state variable, while using a first physical relationship. The same state variable is ascertained while taking into account a plurality of influence variables, which influence the state variable of the air in the intake manifold while using a second physical relationship. A specific adjusting parameter, which represents a specific error in the influence variable, is linked to each influence variable. The adjusting parameters are learned and monitored in the operation of the internal combustion engine. A certain adjusting parameter is learned and monitored in an operating range of the internal combustion engine in which the other adjusting parameters have a lesser influence on the state variable than that certain adjusting parameter, and in this context, the certain adjusting parameter is adjusted in such a way that the state variable ascertained by using the first physical relationship is at least approximately equal to the state variable ascertained by using the second physical relationship.

摘要： In a method for operating an internal combustion engine having a compressor, the diagnosing of a clutch of the compressor is achieved without an additional sensor system. The compressor is turned on via the clutch, and a variable characterizing the air-mass flow to the internal combustion engine is ascertained. A first value of the variable characterizing the air mass flow before turning on the compressor is compared to a second value of the variable characterizing the air mass flow after turning on the compressor by closing the clutch, and an error is detected as a function of a deviation between the first value and the second value of the variable characterizing the air mass flow.
