    摘要： In an aluminum turbocharger bearing housing, there is a potential for wear of the bearing housing at the interface with the turbine housing and/or the bearing system. One area of potential concern is the interface between the flange of the bearing housing and an abutment of the turbine housing. With a protective element at the interface, the potential for wear, and thus misalignment of the rotating assembly with the housings in which they operate can be mitigated. The protective element can be a cap for the bearing housing flange or a heat shield adapted to cover certain faces of the bearing housing flange. The protective element can be a sleeve provided within a bore in the bearing housing. The protective element can be made of a material with a higher heat resistance and/or a higher wear resistance than the aluminum bearing housing.

    摘要： To solve the problems of compressor wheel blade flow separation causing surge type noises when an exhaust gas recirculation (EGR) duct introduces into the compressor exhaust gases to be returned to the engine, the exhaust gas is fed into an annular volume, defined between inner and outer walls or an annular transition cavity shaped as a radially expanded, axially flattened cylindrical space in the compressor inlet, so that the generally unidirectional radial flow from an EGR duct is re-directed and organized as it is turned from generally radial to generally axial, merging with the general inlet flow and presenting the compressor wheel with airflow of “circumferentially uniform” flow velocity.

    摘要： A heat shield for a turbocharger has a disc-like configuration. The heat shield includes an outer radial portion, an outer wall, a connecting wall, and an inner wall. The outer radial portion is disposed circumferentially around an axis of the heat shield. The outer wall extends from the outer radial portion in a first axial direction. The connecting wall extends radially inward substantially perpendicularly from the outer wall. The inner wall extends substantially perpendicularly from the connecting wall in a second axial direction opposite the first axial direction.

    摘要： A drive system (1) for a vehicle includes an electric motor (12) and a gas turbine assembly (28). The electric motor (12) includes a rotor (16) coupled to a drive shaft (14). The gas turbine assembly (28) includes a turbine (30) including a turbine wheel (34) mounted on the drive shaft (14), a burner (70) that burns fuel and provides exhaust gas to drive the turbine wheel (34), and a compressor (50) that provides compressed air to the burner (70). The gas turbine assembly (28) is coupled to the drive shaft (14) of the electric motor (12). The drive system (1) also includes gear train unit (90) that has the drive shaft (14) as an input shaft, has an output shaft (94) connected to vehicle wheels (100), and transmits power from one of the electric motor (12) or gas turbine assembly (28) to the wheels (100).
