摘要： A method for operating an internal combustion engine; in the exhaust area of this engine there is at least one catalytic converter and downstream from the catalytic converter there is an NOx sensor. A device for carrying out this method is also provided. The NOx sensor has a cross-sensitivity to a reagent needed in the catalytic converter. In predefined operating states of the internal combustion engine, e.g., idling and/or overrun, a selection signal is supplied; when this selection signal occurs, the sensor signal supplied by the NOx sensor is interpreted as at least a measure of the reagent leakage.

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 operating a sensor for recording particles in an exhaust gas flow and a device for carrying out the method are provided, in which at least one measure of the exhaust gas flow is ascertained and in which the measure of the exhaust gas flow is taken into consideration in the valuation of the particle sensor signal made available by the particle sensor. The procedure is based on the knowledge that the exhaust gas flow, for instance, the exhaust gas volume flow, has an influence on the particle sensor signal made available by the particle sensor, especially when the measuring effect is based on the depositing of particles on a sensor surface. Using the procedure, a possibly present cross sensitivity of the particle sensor with respect to different exhaust gas flows is taken into consideration, so that the measuring accuracy is increased.

摘要： A method for regenerating a particle filter of an internal combustion engine, of a diesel engine in particular, in which a characteristic quantity for the particle loading is determined to initiate regeneration. More accurate correlation of the particle mass is achieved in that a corrected loading characteristic quantity is formed from the loading characteristic quantity by modifying the loading characteristic quantity using a compression factor which takes into account different degrees of compression of the particles as a function of different operating states of the engine.
