  • Publication number: 20140283503
    Abstract: The present invention relates to a process for determining the state of an exhaust-gas purification device. The exhaust-gas purification device is one which can store gas and/or particles. By means of the proposed process, it is for example possible for the loading state of the exhaust-gas aftertreatment system, for example the oxygen storage state of a catalytic converter which is provided with an oxygen-storing material, such as for example a three-way catalytic converter, to be analysed.

  • Patent number: 6861939
    Abstract: The operating temperature of a gas sensor capable of sensing a gas or a gas composition at a high temperature, for example 1000° C. is maintained constant over the entire volume of a gas sensor layer or function layer (4) secured to a sensor carrier section of the gas sensor by supplying heat to the gas sensor layer (4) in such a way that varying heat dissipations in the sensor carrier section are compensated. For this purpose, an electrical heater for heating the gas sensor layer (4) has individual heater sections with different heating resistance values which depend on a spacing between any individual heater section and the tip of the sensor carrier section.

  • Patent number: 6619108
    Abstract: In a method for identifying the state of an NOx storage catalyst which is cyclically loaded with NOx in the exhaust stream of an internal combustion engine and regenerated, two electrical defining quantities, independent of each other, of the electrically complex impedance of the NOx storage catalyst are detected, one of the two electrical quantities being a measure of the degree of loading of the NOx storage catalyst, and from the second electrical quantity the point in time being identifiable for the end of the regeneration process of the NOx storage catalyst.

  • Publication number: 20020182127
    Abstract: A device and method for removing nitrogen oxides from the exhaust gas from lean-burn internal combustion engines, e.g., diesel engines used in motor vehicles, includes a feed for a reducing agent, an NH3 sensor for measuring the NH3 concentration in the exhaust gas, and an exhaust pipe with NOx reduction catalytic converter. The arrangement configured to feed in reducing agent includes a control circuit for quantitatively continuously controllable supply of reducing agent to the exhaust gas, the control variable of the control circuit being the NH3 concentration measured by the NH3 sensor, and the guide variable of the control circuit being an NH3 concentration value which may be predetermined as a function of the operating point of the internal combustion engine. The NOx reduction catalytic converter is divided into at least two parts which are separate from one another and are arranged in series in the direction of flow of the exhaust gas.

  • Patent number: 6368868
    Abstract: In a method for detecting oxygen concentration in a gas, a functional material in the form of a layer or film made of a semiconducting metal oxide, whose thermoelectric power can be represented as a function of partial oxygen pressure, is subjected to the gas to be analyzed. A temperature difference is created between two points on the functional material, and the voltage difference between the two points of the functional material that are at different temperatures is determined as a measure of oxygen concentration.
