Abstract
(DE)
Die Erfindung betrifft eine Abgasreinigungsanordnung (1) für ein Kraftfahrzeug, die einen Stickstoffoxidspeicher (3) aufweist. Die Abgasreinigungsanordnung (1) ist dafür eingerichtet, Informationen über eine Abgaszusammensetzung des Abgases stromabwärts des Stickstoffoxidspeichers (3) zu erhalten. Die Erfindung betrifft weiter ein Kraftfahrzeug, das eine solche Abgasreinigungsanordnung (1) aufweist, die mit einem Verbrennungsmotor des Kraftfahrzeugs wirkverbunden ist. Mit Hilfe der vorgeschlagenen Abgasreinigungsanordnung (1) wird eine bessere Kenntnis der Abgaszusammensetzung in der Abgasreinigungsanordnung (1) stromabwärts des Stickstoffoxidspeichers (3) ermöglicht, insbesondere um den Stickstoffoxidspeicher zu steuern und zu diagnostizieren.
(EN)
The invention relates to an exhaust gas cleaning assembly (1) for a motor vehicle, comprising a nitrogen oxide storage (3). The exhaust gas cleaning assembly (1) is configured to obtain information regarding an exhaust gas composition of the exhaust gas downstream of the nitrogen oxide storage (3). The invention also relates to a motor vehicle comprising such an exhaust gas cleaning assembly (1) which is operatively connected to a combustion engine of the motor vehicle. With the aid of the proposed exhaust gas cleaning assembly (1), a better knowledge of the exhaust gas composition in the exhaust gas cleaning assembly (1) downstream of the nitrogen oxide storage (3) can be obtained, in particular for controlling and diagnosing the nitrogen oxide storage.

L'invention concerne un système d'épuration de gaz d'échappement (1) pour un véhicule automobile, comprenant un accumulateur d'oxydes d'azote (3). Ce système d'épuration des gaz d'échappement (1) est conçu pour obtenir des informations sur la composition de gaz d'échappement en aval de l'accumulateur d'oxydes d'azote (3). L'invention concerne également un véhicule automobile équipé d'un tel système d'épuration de gaz d'échappement (1) en liaison fonctionnelle avec le moteur à combustion interne du véhicule automobile. Le système d'épuration de gaz d'échappement (1) selon l'invention permet d'obtenir une meilleure connaissance de la composition de gaz d'échappement dans le système d'épuration des gaz d'échappement (1) en aval de l'accumulateur d'oxydes d'azote (3), notamment pour la commande et le diagnostic de l'accumulateur d'oxydes d'azote (3).
