Abstract

Beschrieben wird eine Vorrichtung zur Abgasrückführung für eine Brennkraftmaschine in einem Kraftfahrzeug. Die Vorrichtung weist mehrere Gaskonzentrationssensoren für eine oder mehrere Abgaskomponenten auf und ermöglicht eine Bestimmung und Regelung der Abgasrückführrate ohne Zuhilfenahme eines Kennfeldes. Darüber hinaus zeichnet sich die Vorrichtung durch einen überaus kompakten Aufbau aus.
