Abstract:
(EN) The invention relates to an exhaust gas system (12) for an internal combustion engine of a motor vehicle. Said exhaust gas system comprises a singular exhaust gas inlet line (16), two exhaust gas outlet lines (18) connected in an exhaust gas conducting manner to the exhaust gas inlet line (16), and an active sound damping device which is connected in a sound-conducting manner to both exhaust gas outlet lines (18). The invention also relates to a motor vehicle having an exhaust gas system (12) of this type.
(FR) L'invention concerne un système d'échappement (12) pour un moteur à combustion interne d'un véhicule à moteur. Ce système comprend un tuyau d'admission (16) des gaz d'échappement unique, deux tuyaux d'évacuation (18) des gaz d'échappement reliés au tuyau d'admission (16) des gaz d'échappement de manière à conduire les gaz d'échappement, et un système de silencieux actif qui est relié aux deux tuyaux d'évacuation (18) des gaz d'échappement de façon à conduire le son. L'invention concerne également un véhicule à moteur équipé d'un tel système d'échappement (12).
(DE) Es wird eine Abgasanlage (12) für einen Verbrennungsmotor eines Kraftfahrzeugs beschrieben. Diese umfasst eine singulare Abgaseinlassleitung (16), zwei abgasleitend mit der Abgaseinlassleitung (16) verbundene Abgasauslassleitungen (18) und eine aktive Schalldämpfungseinrichtung, die schallleitend mit beiden Abgasauslassleitungen (18) verbunden ist. Ferner wird ein Kraftfahrzeug mit einer solchen Abgasanlage (12) vorgestellt.
