Abstract

Die vorliegende Erfindung betrifft eine Abgasanlage (2) für eine Brennkraftmaschine (1), insbesondere in einem Kraftfahrzeug, und besitzt zwei parallel durchströmbare Schalldämpfereinrichtungen (3, 4). Eine Schalteinrichtung (11) ermöglicht es, eine Abgasströmung der Brennkraftmaschine (1) wahlweise nur oder fast nur durch die erste Schalldämpfereinrichtung (3) oder nur oder fast nur durch die zweite Schalldämpfereinrichtung (4) oder parallel durch beide Schalldämpfereinrichtungen (3, 4) zu führen. Die beiden Schalldämpfereinrichtungen (3, 4) sind hinsichtlich Dämpfungswirkung und/oder Durchströmungswiderstand unterschiedlich ausgebildet.

Figure 00000001
The invention relates to an exhaust system (2) for an internal combustion engine (1), in particular in a motor vehicle, and has two silencer devices (3, 4) through which flow can occur in parallel. A switching device (11) enables an exhaust gas flow of the internal combustion engine (1) either only or almost only through the first silencer device (3) or only or almost only through the second silencer device (4) or in parallel through both silencer devices (3, 4) to lead. The two silencer devices (3, 4) are designed differently with regard to damping effect and / or flow resistance.
