    Abstract: A turbine wheel for a turbocharger is provided. The turbine wheel includes a plurality of blades and a mid-plane is defined between a pressure side and a suction side of adjacent blades. Each of the blades has a leading edge, and is coupled to the wheel hub along a respective blade hub camber line. The wall has a first radii at the leading edge that extends for a first circumferential distance adjacent to the suction side. The first circumferential distance is at least 12% of a circumferential distance that extends between adjacent blades. The wheel hub includes a plurality of scallops defined through the wall. Each of the scallops is asymmetrical about the mid-plane. For each of the scallops, the wall has a second minimum radii defined offset from the mid-plane toward the suction side and a third minimum radii defined offset from the mid-plane toward the pressure side.

    Abstract: Restricting exhaust gas treatment devices from contacting a washing medium supplied by a washing system may reduce affecting the exhaust gas treatment devices. A washing system (50) may comprise a washing device (52) configured to supply a washing medium to a turbine ( T H ) during an ON mode of the washing system (50) and a fluid flow control system (38). The fluid flow control system (38) may be configured, during an OFF mode of the washing system (50), to direct exhaust gas through the at least one exhaust gas treatment device (41), and during the ON mode of the washing system (50), to restrict a mixture of exhaust gas and washing medium exiting the turbine ( T H ) from being directed through the at least one exhaust gas treatment device (41).

    Abstract: The device serves for sealing off a bearing housing (10), which accommodates a lubricating oil, of an exhaust-gas turbocharger having a rotor (2) which is led through the bearing housing in the direction of an adjoining compressor housing. The device comprises an intermediate wall (11), an axially extending wall extension (111) of the intermediate wall, and a sealing disk (5) fastened to the shaft (20) of the rotor (2). Furthermore, seals (4) are arranged between the rotor (2) and the wall extension (111) or the intermediate wall (11). The intermediate wall (11) separates a large oil chamber (12) arranged in the bearing housing from the wheel rear-side chamber (13) of the compressor wheel (21). A predominantly axially extending cover (6), which leads in at least partially ring-shaped form around the rotor, projects into the large oil chamber from the intermediate wall (11). In particular, the large oil chamber (12) is divided by the cover (6), and by the sealing disk (5) extending in the radial direction, into an outer oil collecting chamber (121) and an inner oil collecting chamber (122). A major part of the lubricating oil conveyed in the direction of the large oil chamber (12) by the bearings (3) of the turbocharger can be collected by the outer oil collecting chamber (121). Lubricating oil that has entered the inner oil collecting chamber (122) is conveyed by gravitational force to an outlet (61) at a large axial distance from the sealing disk (5). The oil quantity that advances further radially inward from the inner oil collecting chamber (122) along the sealing disk (5) in the direction of the seals (4) can be considerably reduced by means of said device, and the sealing action of the bearing housing can be considerably increased. An exhaust-gas turbocharger having a device of said type is likewise presented.
