Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Zwangsanregung einer Lambdaregelung für eine Brennkraftmaschine. Mit Hilfe von zusätzlichen besonders mageren Abgaspaketen, wird das Nach-Kat-Sondensignal stimuliert, um eine schleichende Verschlechterung der Konvertierung zu vermieden.
