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 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 metering a reagent which an emission control device situated in the exhaust duct of an internal combustion engine requires for removing at least one exhaust gas component from the exhaust gas and a device for executing the method are described. The fluid level of the reagent stored in a reagent tank is measured. The measured change in the fluid level is compared to at least one measure for the change in the fluid level calculated as a function of consumption. An error signal is output when the comparison result exceeds a predefined threshold value. This approach enables reliable information to be provided about the fluid level of the reagent in the reagent tank.

摘要： Method for diagnosing a NOx readings recorder which acquires a NOx concentration in an exhaust gas tract of an internal combustion engine and comprises two measuring chambers (110, 120), wherein the exhaust gas to be measured is supplied to the first measuring chamber (110) and an oxygen concentration is set by means of a first oxygen ion pump current (IP1), wherein the second measuring chamber (120) is connected to said first measuring chamber (110) and wherein both measuring chambers are disposed in a solid electrolyte, is characterized by the following steps: the pump voltage at an inner pump electrode in said first measuring chamber (110) and at an oxygen electrode (124) in said second measuring chamber (120) is reduced at a predeterminable operating point such that the oxygen content of the exhaust gas appears in the second measuring chamber (120) at a NOx measuring electrode (126) disposed therein; the oxygen content in said second measuring chamber (120) is determined; said oxygen content is additionally determined by means of a separate device; the two values characterizing the oxygen concentration are compared and a defective sensor is then suggested if the oxygen concentration value determined in the second measuring chamber (120) deviates from the oxygen concentration value determined by means of the separate sensor device by a predeterminable magnitude.

摘要： The invention concerns a procedure to determine a mass of particles or a particle mass flow in an exhaust gas system of an internal combustion engine, whereby at least one resistive particle sensor is disposed in the exhaust gas system of the internal combustion engine. The measured signal change of the particle sensor is compared with a predicted signal change of the particle sensor ascertained-from an engine model. If the measured signal change of the particle sensor and/or the predicted signal change of the particle sensor are corrected while taking into account the influencing variables on the transverse sensitivities of the particle sensor, it is possible when ascertaining the predicted signal change of the particle sensor that a compensation for the transverse sensibilities can result even during dynamic operating point changes of the internal combustion engine, which occur faster than the actuation of the particle sensor. This is the case because the correction can even be implemented for small predicted signal changes, such as those occurring during a currently transpiring operating point of the internal combustion engine. Because the predicted signal changes are ascertained from a set of characteristic curves of the engine model, these measurement intervals capable of being assigned to very short times and for that reason to individual operating points of the internal combustion engine can be determined with the very small predicted signal changes, which are required for this purpose.
摘要翻译：本发明涉及一种确定内燃机排气系统中的颗粒质量或颗粒质量流量的方法，其中至少一个电阻式颗粒传感器设置在内燃机的废气系统中。将粒子传感器的测量信号变化与从发动机模型确定的粒子传感器的预测信号变化进行比较。如果在考虑到颗粒传感器的横向敏感度的影响变量的情况下校正粒子传感器的测量信号变化和/或粒子传感器的预测信号变化，则可以确定粒子的预测信号变化传感器即使在内燃机的动态工作点变化期间也能够产生对横向敏感性的补偿，其发生比颗粒传感器的致动更快。这是因为甚至可以对小的预测信号变化进行校正，例如在内燃机的当前蒸发操作点期间发生的改变。由于预测的信号变化是根据发动机模型的一组特性曲线确定的，所以能够将非常短的时间分配到这些原因的这些测量间隔可以用非常小的预测值来确定信号变化，这是为此目的所需要的。
