Patent ID: 6938729

Claim:
An exhaust gas system for an internal combustion engine ( 1 ) of a motor vehicle, comprising two mufflers ( 3 , 4 ), through which the exhaust gas is able to flow in a parallel fashion, wherein a switching unit ( 11 ) is provided which makes it possible to selectively convey the exhaust gas flow of the internal combustion engine ( 1 ) only or almost exclusively through the first muffler ( 3 ), or only or almost exclusively through the second muffler ( 4 ), or through both mufflers ( 3 , 4 ) in a parallel fashion, and wherein the two mufflers ( 3 , 4 ) are provided differently with respect to their muffling effect or flow resistance, and wherein a control device ( 14 ) is provided which actuates the switching unit ( 11 ) in dependence on the engine load or the speed of the internal combustion engine ( 1 ), and wherein the control device ( 14 ) actuates the switching unit ( 11 ) so that the exhaust gas predominantly flows through the first muffler ( 3 ) in a low speed range, predominantly flows through the second muffler ( 4 ) in a medium speed range, and flows through both mufflers ( 3 , 4 ) in a parallel fashion in an upper speed range.
