    摘要： The invention is directed to diagnosing a catalytic converter capable of storing nitrogen oxides and mounted in the exhaust-gas system of an internal combustion engine. A signal-emitting exhaust-gas probe is provided rearward of the catalytic converter and the exhaust gas forward of the catalytic converter is influenced by increasing components in the exhaust gas which are effective as a reducer thereby triggering a change of the signal. The time elapsed between the start of the influencing and the change of the signal is evaluated to diagnose the catalytic converter.

    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 gas sensor and a method for its manufacture are described. The gas sensor has a solid electrolyte having at least one measuring electrode and one porous protective coating. The measuring electrode has an electrically conductive base layer and a further layer, the further layer god being deposited in the pores of the porous protective coating adjacent to the base layer via galvanic deposition. In order to deposit the further layer via galvanic deposition, the basic body, which has been fused with the base layer and the protective coating via vitrification, is immersed in a galvanizing bath, the base layer being connected as the cathode.

    摘要： An oxygen sensor for determining the oxygen concentration in the exhaust gas flow of an internal combustion engine. The sensor includes an outer electrode exposed to the exhaust side and a reference electrode exposed to the ambient air. In the sensor, a space adjacent to the reference electrode or surrounding the reference electrode has an adsorbing and/or absorbing agent, which is introduced, for example, in a loose powder packing or a multiple pellet packing. Other versions of the novel oxygen sensor also have an oxygen supplying material, such as, for example, Mn-oxide, Ba-oxide and/or Ce-oxide, to help promote combustion of exhaust gas components/pollutants and any residue chemicals left remaining from the sensor manufacturing process.
