Abstract

Die Erfindung betrifft einen Verbrennungsmotor (1) mit einem Abgassystem, welches eine Vorkatalysatoreinrichtung (3) und eine stromab der Vorkatalysatoreinrichtung (3) angeordnete Hauptkatalysatoreinrichtung (4) aufweist, und mit einer Kraftstoffregelungs-Vorrichtung (11) zur Gemischregelung in Abhängigkeit von dem Signal von zumindest einem im Abgas angeordneten Sauerstoffsensor. Erfindungsgemäss ist ein erster Sauerstoffsensor (5) stromab der Vorkatalysatoreinrichtung (3) und stromauf der Hauptkatalysatoreinrichtung (4) angeordnet, dessen Signal der Kraftstoffregelungs-Vorrichtung (11) zur Gemischregelung zugeführt wird. Ferner umfasst die Erfindung ein Verfahren zum Betrieb eines erfindungsgemässen Verbrennungsmotors.
