    摘要： A device for monitoring an exhaust gas catalytic converter in the exhaust system of an internal combustion engine, includes a measuring apparatus that is arranged in the exhaust system in such a way that, in the greatest part of the operating range of the internal combustion engine, it assumes a temperature that is correlated with a temperature of the exhaust gas catalytic converter. The measuring apparatus has a temperature-sensitive component with a temperature-dependent characteristic component parameter that changes either abruptly at a predetermined transition temperature or temperature range, or continuously in a predetermined way as a function of the temperature. A control and evaluation unit connected to the measuring arrangement detects the characteristic component parameter and/or a change in the latter, and correlates it with an aging state of the exhaust gas catalytic converter.

    摘要： An exhaust gas sensor is proposed for detecting a gas component in the exhaust gas of an internal combustion engine, having a control and evaluation unit and a sensor unit with an electrode structure with a first terminal and a second terminal, and a method for operating an exhaust gas sensor to determine the concentration of a gas component in the exhaust gas of an internal combustion engine is also proposed. The control and evaluation unit applies a bias voltage to the first terminal and/or the second terminal of the electrode structure, it being possible for the level of the bias voltage to be set in dependence on a characteristic of the sensor and/or in dependence on a loading of the sensor. A bias voltage is applied to the first terminal and/or to the second terminal of the electrode structure, with the level of the bias voltage being set in dependence on a characteristic of the sensor and/or in dependence on a loading of the sensor.

    摘要： A method for determining the reducing agent concentration (NH3) in the exhaust-gas flow of an internal combustion engine, using a zeolitic NH3 gas sensor that supplies a base measuring value, which is initially corrected by an offset value and a correction value that depends on the H2O concentration of the exhaust gas to form an intermediate value. The intermediate value is subsequently corrected by an additional value that depends on the NOx and NH3 concentration of the exhaust gas. In particular at or above the limits for the operating range, the accuracy of the method increases for one of the following conditions: gas compositions with NOx concentrations >500 ppm, extremely low NH3 concentrations 100 ppm.

An electrically conductive shielding structure is provided between the sensor unit and the electric heating arrangement in order to shield the measurement process at the sensor unit from interferences owing to the heating process, thereby reducing or preventing the effects of electrical fields caused by voltages applied to the heating arrangement from altering or disrupting the measurement process.

    摘要： A device determined the state of a soot particle filter of an internal combustion engine. An electrical measuring arrangement is embodied as a soot sensor for measuring a soot deposit and comprises an electrical component with a conductor structure for exciting an electrical or magnetic field which can be influenced by the soot deposit and characterizes an electrical or magnetic characteristic variable of the component. A measuring arrangement measures the electrical or magnetic characteristic variable of the component as a measure of the soot deposit. The conductor structure is arranged so that a partial volume region of the soot particle filter is penetrated by the electrical field, and the partial volume region forms part of the component.
