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.

Figure 00000001
A device for exhaust gas recirculation for an internal combustion engine in a motor vehicle is described. The device has a plurality of gas concentration sensors for one or more exhaust gas components and enables the exhaust gas recirculation rate to be determined and regulated without the aid of a characteristic diagram. In addition, the device is characterized by an extremely compact structure.
