Abstract: A turbocharger (1) includes a compressor section and a cast turbine section. The turbine section includes a turbine wheel (4), and a turbine housing (11) that defines a gas inlet (13), a gas outlet (10), a volute (9) disposed between the gas inlet (13) and the gas outlet (10). The turbine housing (11) also includes vanes (20) that protrude integrally from, and have a fixed orientation relative to, an inner surface of the turbine housing (11). The turbine wheel (4) is disposed in the turbine housing (11) between the volute (9) and the gas outlet (10), and the vanes (20) are disposed in the turbine housing (11) between the turbine wheel (4) and the volute (9). A method of casting the turbine housing (11) and the vanes (20) together as a single piece is described.

Abstract: A turbocharger includes a turbine housing defining a turbine housing interior, a turbine wheel disposed within the turbine housing interior, a shaft coupled to and rotatable by the turbine wheel, a compressor housing defining a compressor housing interior and a flow path, and a compressor wheel disposed within the compressor housing interior and coupled to the shaft. The compressor wheel has a hub coupled to the shaft, and a plurality of impeller blades extending radially from the hub. The plurality of impeller blades define an inducer end having an inducer diameter, and an exducer end having an exducer diameter greater than the inducer diameter. The inducer diameter and the exducer diameter establish a compressor trim. The compressor wheel also has a compressor wheel shroud disposed about the plurality of impeller blades. The compressor wheel shroud encloses the plurality of impeller blades to define a shroud interior.

Abstract: A forced induction device includes a compressor wheel, a housing, and an intake insert. The compressor wheel has an inducer diameter and an exducer diameter. The housing includes a housing cover member having a central portion and a housing intake portion extending from the central portion. The central portion defines a compressor cavity in which the compressor wheel rotates and having a cavity inlet diameter larger than the inducer diameter. The intake insert defines a conduit extending therethrough from a proximal end to a distal end of the intake insert. The proximal end is received by the housing intake portion with the conduit in fluidic communication with the compressor cavity. At the proximal end, the conduit the conduit has a proximal inner diameter that is less than cavity inlet diameter and the inducer diameter, and the distal end is configured to connect to a coupling portion of an air source.
