Abstract

In bestimmten Betriebszuständen, beispielsweise nach Schließen einer Drosselklappe, schlägt sich an der Saugrohrwand Kraftstoff nieder, dessen Abdampfen die Zusammensetzung des dem Brennraum eines Zylinders zugeführten Gemisches beeinflußt. Um diesen Einfluß zu korrigieren, wird in das Saugrohr 6, von einer elektrischen Steuereinrichtung 18 gesteuert, durch ein Korrekturluftventil 16 hindurch Korrekturluft eingeführt.
