    摘要: A method and a device for operating an internal combustion engine having exhaust-gas recirculation are provided, which make it possible to dispense with an ambient-pressure sensor. In this context, an intake-manifold pressure and an ambient pressure are modeled. The intake-manifold pressure is modeled as a function of the modeled ambient pressure. The intake-manifold pressure is also measured. The modeled intake-manifold pressure is compared to the measured intake-manifold pressure. The modeled ambient pressure is adapted as a function of the comparison result. The modeled ambient pressure is adapted only when the exhaust-gas recirculation is inactive.

    摘要: A method and a device are provided for operating an internal combustion engine, which make possible an improved characteristics curve correction of an actuator in an air supply of the internal combustion engine. In the process, an air mass flow supplied to the internal combustion engine is influenced via the actuator in an air supply. For the setting of an actuating position of the actuator having a specified, e.g., minimum, air mass flow, starting from a specified actuating position, the actuator is moved by an offset value of the actuating position. The offset value of the actuating position is corrected as a function of an offset value for the air mass flow.

    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.
