    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： The invention relates to a method for diagnosing a particle filter used for filtering particles out of the exhaust gas of an internal combustion engine, wherein a collecting particle sensor is disposed downstream of the particle filter in the direction of flow of the exhaust gas and wherein a measurement for the loading of the particle sensor is determined from an output signal of the particle sensor. Provision is thereby made for the temporal integral of a parameter correlating to the particle emissions of the internal combustion engine to be formed during a measurement cycle, for the measurement for the loading of the particle sensor to be associated with the integral at least one measurement point in time during the measurement cycle and for a defective particle filter to be suggested if the measurement for the loading of the particle sensor is higher than a loading threshold value associated with the integral or if the integral is lower than an integral threshold value associated with the measurement for the loading of the particle sensor. The invention further relates to a device for carrying out the method. The method and the device allow for the diagnosis of the functionality of a particle filter in the exhaust gas of an internal combustion engine during any operating conditions passed through by the internal combustion engine.

    摘要： A method for monitoring the capability of a catalytic converter to convert nitrogen monoxide into nitrogen dioxide in the exhaust gas of an internal combustion engine, the catalytic converter being arranged in an exhaust gas duct of the internal combustion engine and the catalytic converter being followed downstream by a collecting particle sensor. It is in this case provided that, in a monitoring cycle, a decrease in the particle loading of the particle sensor during the operation of the internal combustion engine under predetermined operating conditions is taken to conclude an adequate capability of the catalytic converter to convert from nitrogen monoxide to nitrogen dioxide.

    摘要： A procedure to diagnose a particle filter disposed in an exhaust gas area of an internal combustion engine as well as a device to implement the procedure is proposed. Provision is made to ascertain the degree of efficiency of the particle filter on the basis of the upstream particle flow occurring upstream in front of the particle filter and on the basis of the downstream particle flow occurring downstream behind the particle filter. The ascertainment of the degree of efficiency of the particle filter allows for an On-Board-Diagnosis of the particle filter, with which compliance with specified exhaust gas threshold values can be assured.

    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.
