摘要： A solid electrolyte-based sensor element of a gas sensor for determining a gas component in a gas mixture is described, in particular for determining the concentration of oxygen and/or nitrogen oxides in exhaust gases of internal combustion engines. The sensor element has an electrochemical cell that includes a first and a second electrode, both electrodes being located in internal gas spaces of the sensor element.

摘要： A sensor element for a sensor for determining the oxygen concentration in the exhaust gas of internal combustion engines, e.g., for a broadband lambda sensor, is provided. The sensor element has a solid electrolyte forming a pump cell together with an inner electrode inside a cavity, and an outer electrode exposed to the exhaust gas on the outside. The sensor element also includes a prechamber formed in the solid electrolyte, and a diffusion channel formed in the solid electrolyte, the diffusion channel connecting the prechamber and the cavity, and being filled with a diffusion barrier. To prevent measuring inaccuracies of the sensor in the presence of very high quantities of hydrocarbons in the exhaust gas, a catalytic converter for the oxidation of hydrocarbons is located in the prechamber, the catalytic converter being configured as an electrochemical catalytic converter having two electrodes electrically connected with one another.

摘要： This invention provides a method for monitoring the function and/or regeneration of a gas probe. The invention includes a measurement of first and second pump currents of the gas probe and a determination of a difference between the first and second pump currents (&Dgr;I). If &Dgr;I exceeds a pregiven value, then a saturation pump voltage is applied and the difference between a resulting pump current and a previously stored minimum pump current (&Dgr;I plus) is determined. If &Dgr;I plus exceeds a pregiven value, then a regeneration voltage is applied.
