Abstract

Es wird ein Verfahren zur Adaption eines Kraftstoff-Luft-Gemisches bei einem Verbrennungsmotor und eine zugehörige elektronische Steuereinrichtung vorgeschlagen, bei dem verschiedene Arten von Gemischabweichungen adaptiert werden und die eine Verkürzung der Gemischadaptionszeit ermöglicht. Während oder nach Adaption einer ersten Art von Gemischabweichung wird der Einfluss der ersten Art von Gemischabweichung auf eine zuvor erfolgte Adaption einer zweiten Art von Gemischabweichung geschätzt. Die Adaption der zweiten Art von Gemischabweichung wird in Abhängigkeit dieser Schätzung korrigiert.

Figure imgaf001
A method is proposed for adapting a fuel-air mixture in an internal combustion engine and an associated electronic control device, in which different types of mixture deviations are adapted and which enables a shortening of the mixture adaptation time. During or after adaptation of a first type of mixture deviation, the influence of the first type of mixture deviation on an earlier adaptation of a second type of mixture deviation is estimated. The adaptation of the second type of mixture deviation is corrected as a function of this estimate.
