Title: TURBINE FOR AN EXHAUST GAS TURBOCHARGER OF AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a turbine (26) for an exhaust gas turbocharger (24) of an internal combustion engine (10), having a turbine housing (30) which has a receiving region (32), having a turbine wheel (34) which is arranged at least partially in the receiving region (32) and can be rotated relative to the turbine housing (30) about a rotational axis (36), having at least one duct (58, 60, 114, 116) which is formed by way of the turbine housing (30), can be flowed through by exhaust gas of the internal combustion engine (10), and opens into the receiving region (32), for guiding the exhaust gas which flows through the duct (58, 60, 114, 116) into the receiving region (32) and to the turbine wheel (34), and having a tongue slide (66) which has at least one tongue (68, 70) which is assigned to the duct (58, 60, 114, 116), can be displaced relative to the turbine housing (30) about the rotational axis (36), and by means of which a flow cross section of the duct (58, 60, 114, 116) can be set, wherein the exhaust gas which flows through the duct (58, 60, 114, 116) can be guided via the flow cross section into the receiving region (32) and can be fed to the turbine wheel (34), wherein the turbine (26) is configured as a mixed flow turbine, in which a respective flow direction, in which the exhaust gas flows during operation of the turbine from the duct (58, 60, 114, 116) through the respective flow cross section into the receiving region (32) and to the turbine wheel (34), runs obliquely with respect to the axial direction and obliquely with respect to the radial direction of the turbine wheel (34).
