Patent ID: 8826651

Claim:
An exhaust system for an internal combustion engine comprising a first exhaust tract assigned to a first group of cylinders of the internal combustion engine, and a second exhaust tract assigned to a second group of cylinders of the internal combustion engine, the first exhaust tract and the second exhaust tract being coupled to one another by a connecting line, wherein a common bypass line branches off from the connecting line for coupling the exhaust tracts, such that exhaust gas emanating through the first exhaust tract is also branched off from and bypasses the first exhaust tract via the connecting line, and exhaust gas emanating through the second exhaust tract is also branched off from and bypasses the second exhaust tract via the connecting line, and the exhaust gas is discharged from the connecting line via the common bypass line, wherein the common bypass line opens into either a silencer or an exhaust gas purification device downstream of the connecting line, with respect to a direction of flow of exhaust gas, wherein the connecting line is assigned a first shut-off device between a point of connection of the connecting line to the first exhaust tract and a point of connection of the common bypass line to the connecting line, and a second shut-off device between a point of connection of the connecting line to the second exhaust tract and the point of connection of the common bypass line to the connecting line.
