摘要： A sensor for determining gas components and concentrations in a gas mixture that is particularly suitable for analyzing HC, NOx and CO in exhaust gases of internal combustion engines in the sensor, an outer electrode, that is separated from an MOx electrode by an electrolyte layer, is applied on a substrate. In this context, the outer electrode and the MOx electrode are in communication with the gas mixture to be analyzed. In addition, the outer electrode contains a region that is in contact with a gas-permeable tunnel layer which in turn contains a region that is directly exposed to the gas mixture to be analyzed, so that the gas to be analyzed can be supplied to the outer electrode via the gas-permeable tunnel layer.

摘要： The invention is directed to a method and an arrangement for diagnosing a catalytic converter arranged in the exhaust-gas system of an internal combustion engine. The catalytic converter is configured to have an oxygen storage capability and a nitrogen oxide storage capability. A first exhaust-gas probe is mounted rearward of the catalytic converter and a second exhaust-gas probe is mounted forward thereof. The oxygen concentration of the exhaust gas forward of the catalytic converter is alternately increased and decreased so that the signals of both exhaust-gas probes change. A first phase shift between the signals of both exhaust-gas probes is detected when the oxygen concentration increases and a second phase shift between the signals is detected when the oxygen concentration decreases. The difference of the phase shifts is determined and a fault signal is outputted and/or stored when this difference does not reach a pregiven threshold.

摘要： A sensor for detecting combustible gases in a test gas. The core of this sensor is comprised of a sensitive layer based on a semiconducting metal oxide that is deposited on a ceramic substrate and for which the electrical resistance provides information on the concentration of combustible gases in a test gas. The sensitive layer (3) is comprised of a compound (12) of sintered-together grains (15) of the semiconducting metal oxide, the surface of which is coated with gold and/or a gold alloy. The semiconducting metal oxide in this case is stannic oxide (SnO.sub.2), indium oxide (In.sub.2 O.sub.3), titanium oxide (TiO.sub.2) or another n-semiconducting metal oxide or metal mix oxide. The gold alloy, for example, is composed of 66 mol % gold and 33 mol % palladium (Pd).

摘要： The invention is directed to a method of determining the sensitivity of a hydrocarbon sensor for an internal combustion engine generating exhaust gas during the operation thereof. The hydrocarbon sensor includes a probe electrode subjected to the exhaust gas and a heater device for heating the probe electrode whereby a voltage (U) is generated in the sensor and is present at the probe electrode with the voltage (U) being a criterion for the concentration of hydrocarbon molecules in the exhaust gas. The voltage (U) present on the probe electrode is short circuited for a short time and the voltage (U) is measured as a function of time to obtain a voltage curve. A conclusion is then drawn as to the sensitivity of the hydrocarbon sensor from the voltage curve. The invention is also directed to an arrangement for carrying out the invention.
