Abstract

Zur Messung der NOx-Konzentration im Abgas einer Brennkraftmaschine (20) wird ein Dickschicht-Meßaufnehmer (24) verwendet, der zwei Meßzellen aufweist. Aus einem in der ersten Meßzelle fließenden Sauerstoffionen-Pumpstrom wird der 1/μ-Wert des Abgases bestimmt, beispielsweise mittels eines Kennfeldes, und aus diesem, beispielsweise mittels einer zuvor in einer Kalibriermessung bestimmten Kennlinie, ein Meßfehler bestimmt, mit dem die gemessene NOx-Konzentration korrigiert werden kann. Der Erfindung liegt die Erkenntnis zugrunde, daß der Meßfehler vom Luftverhältnis im Abgas abhängt. Drückt man dieses durch den 1/μ-Wert aus, kann bei der Korrektur auf eine rechenaufwendige Division verzichtet werden.
