Abstract

Die Erfindung betrifft ein Verfahren zur Ermittlung eines Lambdawertes eines Abgases einer Verbrennungskraftmaschine mit einer Lambdasonde, insbesondere einer Breitband-Lambdasonde, wobei die Lambdasonde in einem Abgaskanal der Verbrennungskraftmaschine angeordnet ist und ein Meßsignal der Lambdasonde in Abhängigkeit von einem vorgebbaren Korrekturwert kw den Lambdawert liefert (Kalibrierung) sowie der Verbrennungskraftmaschine Mittel zugeordnet sind, die eine Erfassung eines Luftmassenstroms und einer zugeführten Kraftstoffmasse ermöglichen.
Es ist vorgesehen, daß zur Festlegung des Korrekturwertes (kw)
  • (a) in einem ersten Betriebspunkt (p1) der Verbrennungskraftmaschine mit λ = 1 (stöchiometrischer Betrieb) eine Kraftstoffmasse (mK1) und ein Luftmassenstrom (mL1) erfaßt wird,
  • (b) nachfolgend in einem zweiten Betriebspunkt (p2) der Verbrennungskraftmaschine mit λ ≠ 1 (Mager- oder Fettbetrieb) eine Kraftstoffmasse (mK2) und ein Luftmassenstrom (mL2) erfaßt wird,
  • (c) in Abhängigkeit von den Luftmassenströmen (mL1, mL2) und den Kraftstoffmassen (mK1, mK2) der Betriebspunkte (p1,p2) der Korrekturwert (kw) für den Lambdawert des Betriebspunktes (p2) gebildet wird.
