    摘要: An internal combustion engine, in particular for a motor vehicle, is described. The internal combustion engine is provided with a control unit for determining a setpoint fuel mass and/or a setpoint air mass as a function of a setpoint torque. The control unit is also provided for transitioning from a first operating mode to a second operating mode of the internal combustion engine. An actual torque is determined by the control unit during the transition to the second operating mode of the internal combustion engine. A torque difference between the setpoint torque and the actual torque is also calculated by the control unit. Finally, the setpoint fuel mass and/or the setpoint air mass is controlled by the control unit as a function of the torque difference.

    摘要: A method and a device for correcting for tolerances in a transmitter wheel are described. The transmitter wheel has a plurality of approximately equidistant marks that are scanned by a pickup. The pickup supplies a pulse train on the basis of which measured values are formed, with correction values being determined on the basis of a comparison of the individual measured values with a reference value. The measured values are filtered with at least one first and one second frequency-selective filtering.

    摘要: Described is a method for controlling a temperature downstream of a catalyst in the exhaust tract of an internal combustion engine including a first control loop in which a first control variable is calculated from a first deviation that is calculated from a first actual value and a first setpoint value and influences an intra-engine heat generation. In the process, the first actual value is determined as a measure of a temperature downstream of the catalyst. The method features a second control loop in which at least one second control variable is calculated from a second deviation that is calculated from a second actual value and a second setpoint value; a temperature upstream of the catalyst being determined as the second actual value. Also described is a controller which controls the sequence of such a method.

    摘要: A method for operating an internal combustion engine, in whose exhaust region, in the direction of flow of the exhaust gas, there are situated a first broadband lambda sensor which makes available a first lambda signal, an NOx adsorption catalyst and a second broadband lambda sensor which makes available a second lambda signal, in which the NOx adsorption catalyst cyclically stores the NOx emissions of the internal combustion engine, and is regenerated within the scope of a nominal regeneration by the operation of the internal combustion engine using a rich/stoichiometric air/fuel mixture, and a device for carrying out the method are provided. An intensified regeneration, compared to a nominal regeneration, of the NOx adsorption catalyst is undertaken, which supports a better setting of the thermodynamic equilibrium in the exhaust gas compared to the nominal regeneration. At the end of the intensified regeneration, at a still rich/stoichiometric air/fuel mixture, a plausibility check/correction of the first lambda signal using the second lambda signal is provided.

    摘要: A method for correcting the position of the angle marks of an incremental gear of a rotary speed sensor and/or rotary angle sensor of an internal combustion engine and to a system therefor. The method is characterized by the following steps: a) recording the angle marks using the rotary speed sensor and/or the rotary angle sensor, b) measuring the combustion chamber pressure in the respective cylinder of the internal combustion engine, c) assigning a measured pressure value to the recorded angle mark positions, d) possibly correcting the measured pressure values in a signal-conditioning device, e) storing the recorded angle mark positions with the appertaining, measured pressure values in a measured value table, f) storing of the ideal pressure values derived at the ideal angle mark positions in a reference table, g) comparing the pressure values, that were measured and possibly preprocessed in the signal-conditioning device to the ideal pressure values, h) determining deviations of the measured angle mark positions from the ideal angle mark positions, at the corresponding cylinder pressure values in an evaluation unit, and i) correcting the measured angle mark positions by the deviations determined.
