Abstract

Die Erfindung betrifft ein Verfahren zur Überwachung der verstärkten Bildung von Stickoxiden während der Verbrennung fossiler Brennstoffe, insbesondere während der Verbrennung im Zylinder eines Verbrennungsmotors. Hierzu wird eine Folge erster Leitfähigkeitswerte auf Grundlage der im Verbrennungsgas enthaltenen negativen Teilchen gebildet und anschließend mit einer Folge zweiter Leitfähigkeitswerte verglichen, die auf Grundlage positiv geladener Teilchen im Verbrennungsgas gebildet worden ist. Eine verstärkte Bildung von Stickoxiden wird dann festgestellt, wenn die Folge erster Leitfähigkeitswerte und die Folge zweiter Leitfähigkeitswerte während des Vergleiches zunehmend voneinander abweichen.
