In a turbocharger for an internal combustion engine of a motor vehicle, comprising a turbine housing having first and second spiral passages, each of which is connected to at least one exhaust gas line of an exhaust train of the internal combustion engine and a turbine wheel disposed within a rotor chamber of the turbine housing and connected to a compressor impeller via a drive shaft for rotation with the impeller, the exhaust gas of the internal combustion engine can be routed through the spiral passages for admission to the turbine wheel via the first and second spiral passages which have different wrap angles around the turbine wheel.
A turbocharger for an internal combustion engine (10) of a motor vehicle, comprising a turbine housing (12) having at least one first and one second spiral inlet passage (14a, 14b), each of which can be coupled to at least one of several exhaust gas lines (16a, 16b) of an exhaust train (18) of the internal combustion engine (10) and through each of which exhaust gas can flow independently, and further comprising a turbine wheel (22) located within a rotor chamber (20) of the turbine housing (12), which is provided for driving a compressor impeller (25) coupled to the turbine wheel (22) for rotation therewith via a support shaft (24), wherein the exhaust gas of the internal combustion engine, which can be routed through the at least two spiral passages (14a, 14b), can be admitted to the turbine wheel (22), the first and second spiral passages (14a, 14b) having different wrap angles (φS) around the turbine wheel (22).
An internal combustion engine (10) for a motor vehicle, comprising at least two cylinders (11a-f) or two cylinder groups (34a, 34b) to which are assigned at least two exhaust gas lines (16a, 16b), and further comprising a turbocharger with a compressor (27) located in an intake train (40) of the internal combustion engine (10) and a turbine (23) located in a exhaust train (18) of the internal combustion engine (10), wherein the turbine (23) comprises a turbine housing (12) with at least one first and one second spiral passage (14a, 14b), each of which is coupled to at least one of the two exhaust gas lines (16a, 16b) of the exhaust train (18) and through each of which exhaust gas can flow independently, and with a turbine wheel (22) located within a locating chamber (20) of the turbine housing (12), to which the exhaust gas of the internal combustion engine (10), which can be routed through the first and second spiral passages (14a, 14b), can be admitted to drive a compressor impeller (25) of the compressor (27) which is coupled thereto for rotation therewith via a drive shaft (24), the first and second spiral passages (14a, 14b) having different wrap angles (φS).
