Abstract
An exhaust gas system, in particular for an internal combustion engine, includes an exhaust gas line. The exhaust gas line has at least one turbocharger and a thermoelectric converter arrangement which is arranged downstream of the turbocharger in the flow direction of an exhaust gas and which includes a thermoelectric converter stage. The exhaust gas line is paired with at least one bypass line, which branches out from the exhaust gas line upstream of the turbocharger in an exhaust gas-conductive manner in order to discharge at least one part of the exhaust gas into the at least one bypass line. The at least one bypass line opens into the exhaust gas line downstream of the thermoelectric converter stage in an exhaust gas-conductive manner.
Claims18
An exhaust system for an internal combustion engine, the exhaust system comprising:
- an exhaust line comprising at least one exhaust-gas turbocharger and, arranged downstream viewed in a flow direction of an exhaust gas, a thermoelectric converter arrangement having a thermoelectric converter stage;
- and
- at least one bypass line configured to branch-off the exhaust line in an exhaust gas-conducting fashion upstream of the exhaust-gas turbocharger, wherein at least a fraction of the exhaust gas is discharged into the bypass line, and
- the bypass line opens in an exhaust gas-conducting fashion into the exhaust line downstream of the thermoelectric converter stage.
