TURBINE FOR AN EXHAUST GAS TURBOCHARGER AND INTERNAL COMBUSTION ENGINE WITH SUCH A TURBINE

摘要

The invention relates to a turbine (44) for an exhaust gas turbocharger (20) of an internal combustion engine (10), having a turbine housing (50) through which exhaust gas from the internal combustion engine (10) flows and in which a turbine wheel (66) is received at least in some regions so as to be rotatable about an axis of rotation (22). The turbine housing has at least two flow sections (42, 48) through each of which at least a part of the exhaust gas can flow and which are fluidically separated from one another at least in some regions. At least one nozzle (70, 72) is associated with said flow sections, via which nozzle exhaust gas flowing through the respective flow section (42, 48) can be fed to the turbine wheel (66) so that exhaust gas can act on the turbine wheel (66). A first adjusting unit (74) is associated with at least a first one of the nozzles (70, 72), wherein said adjusting unit can variably adjust a flow cross-section (S?,SAGR) of the first nozzle (70, 72) which has flowing through it the exhaust gas which flows through the associated flow section (70, 72). A second adjusting unit (76) is provided which is disposed at least partially in a turbine wheel outlet region (78) and by means of which flow conditions can be influenced at least substantially in the turbine wheel outlet region (78).
