摘要： To extend temperature range of solid electrolyte ion conductive-type gas sensors, particularly for the exhaust gases from internal combustion engines, and to prevent leakage currents between a heater element and the solid electrolyte body at temperatures just above the response temperature of the sensor, but below its normal operating temperatures, that is, even in the range of between 250.degree. C. to 400.degree. C., a layer-like shielding electrode (18,29) is provided, positioned between the solid electrolyte body (11,25) and the insulating layer (17,31). The shielding electrode is galvanically connected to the return line (21,33) of the heating element. In accordance with one embodiment, the shielding electrode and one of the operating electrodes, for example, the sensing electrode (29), can be the same metallic film or element applied to the sensor, with an additional electrical insulation layer (32) interposed in the region between the film electrode (29) and the solid electrolyte body (25), the heater element (16,30) being positioned with the interposition of the electrical insulating layer over the film electrode in that region. Preferably, the width of the respective insulating layers decreases in a direction away from solid electrolyte body.The system is applicable both to potentiometric, as well as polarographic-type sensors, of, selectively, closed tubular or plate-like construction, with electrodes exposed either to a reference gas or having, respectively, different catalytic activity.

摘要： A device and a method for detecting ammonia, especially for detecting an NH3 slip emission in a catalytic converter arrangement, a gas, especially an exhaust gas of a lean-mixture-driven internal combustion engine, being supplied to an SCR catalytic converter via a first gas supply device, and ammonia being supplied via a second gas supply device. The device includes a first arrangement, especially an oxidation catalytic converter, which prior to the supplying of the gas to the SCR catalytic converter, initially at least substantially oxidizes the oxidizable gas components contained in the gas. Emerging gas from the SCR catalytic converter is analyzed by a second arrangement, especially a gas sensor, with respect to the oxidizable components contained in it. The gas sensor may detect oxidizable gas components, including in a non-selective manner, and is connected via a processing unit and a control unit to a dosing system, which regulates the supply of ammonia.

摘要： An electrochemical gas sensor and a method for determining the concentration of gaseous components in a gas mixture, particularly of NOx in exhaust gases of internal combustion engines. The gas sensor includes a first measuring-gas compartment which is in communication with the measuring gas, and two additional measuring-gas compartments which are connected to the first measuring-gas compartment via diffusion barriers. The first measuring-gas compartment contains a first pump cell which, with the aid of pump electrodes arranged on a solid electrolyte, transports oxygen into and out of the measuring-gas compartment. The second and third measuring-gas compartments contain further pump cells, the second measuring-gas compartment being used for measuring the oxygen concentration of the mixture, and the third measuring-gas compartment being used for measuring the sum of the oxygen concentration and the concentration of the gaseous component in the gas mixture. The pump current measured between two pump electrodes arranged on a solid electrolyte is used by both amperometric measuring pump cells as a measured quantity, and a measuring signal proportional to the concentration of the gaseous component to be determined is obtained through subtraction of both pump currents.

摘要： In order to provide a method and arrangement for analytical determination of the relative amounts of exhaust gas components, except for water, but including hydrogen in the rich range or oxygen in the lean range, and for determining a &lgr; value, in which the exhaust gas sample can be taken at any arbitrary location, an arrangement is provided in which at least one portion of the exhaust gas is passed through a catalytic reactor (2, 22), a condenser (3,23) connected to the catalytic reactor to receive the gas passed through it, and, after passing through the condenser, the gas passes through an IR spectrometer and by a &lgr;-sensor. The oxidizable and reducible components of the exhaust gas are reacted with each other in the catalytic reactor which is heated to temperatures greater than 450° C. The relative amounts of CO2, hydrocarbons and, if present, CO are measured with the IR spectrometer and either the relative amount of hydrogen in the rich range or of O2+½ NO in the lean range is determined with the help of the signal (Ip) from the &lgr;-sensor. A &lgr; value is calculated from the measured exhaust gas component concentrations or relative amounts.

摘要： A method for selective rich/lean control of a combustion mixture using an electrochemical gas sensor. The method makes possible the operation of an NOx adsorption catalyst, which stores excess NOx present in the exhaust gas in a storage phase, the exhaustion of the storage capacity of the catalyst being expressed as an increase in the NOx concentration in the exhaust-gas stream after the catalytic converter, and which converts the stored NOx in a subsequent regeneration phase using a rich exhaust-gas mixture, the end of this reaction being able to be seen in a reduction in the lambda value of the exhaust-gas stream after the catalytic converter. The electrochemical gas sensor underlying the method for operating the NOx adsorption catalyst is operated such that the NOx and the oxygen concentrations in the exhaust-gas stream can be alternately determined using one and the same gas sensor.
