Abstract: A turbocharger includes a compressor housing, a turbo shaft, a bearing housing, a bearing cartridge, and a spacer. The compressor housing includes a backplate. The turbo shaft extends through the backplate and the bearing housing, and is rotatable about an axis. The backplate is positioned between an interior of the compressor housing and an interior of the bearing housing. The bearing cartridge is positioned in the bearing housing and rotatably supports the turbo shaft therein. The spacer is engaged with the bearing housing and an outer radial portion of the bearing cartridge to prevent rotation therebetween. The spacer includes a deflector formed integrally therewith that directs a lubricant axially away from the compressor housing.

Abstract: A system includes a divided volute turbocharger having variable turbine geometry. The turbocharger includes a turbine housing, first and second volutes separated by a wall having a first and second tongue, and a turbine housing outlet. The system also includes a turbine wheel disposed in the turbine housing and a vane ring disposed in the turbine housing between the turbine wheel and the volutes. The vane ring includes a plurality of rotatable vanes disposed on a vane ring surface of an annular disk in an asymmetric or asymmetric vane pattern that receives the turbine wheel therewithin and a pair of aerodynamic spacers spaced circumferentially outward of the plurality of vanes with each spacer positioned adjacent to a respective one tongue, with the spacers and vanes directing and controlling the flow of exhaust from the volutes into the turbine wheel with generally equal flow while significantly reducing HCF forcing function.

Abstract: An entryway system includes a divided volute turbocharger having variable turbine geometry (VTG). The turbocharger includes a turbine housing, first and second volutes separated by a wall having a first and second tongue, and a turbine housing outlet. The system also includes a turbine wheel disposed in the turbine housing and a vane ring disposed in the turbine housing between the turbine wheel and the volutes. The system includes design modifications of one or more of the VTG components and/or locations of such components to manipulate the aerodynamic forces and/or subsequent mechanical loads in the VTG mechanism of the entryway system to mitigate VTG component wear during normal usage.

Abstract: High cycle fatigue (HCF) in a turbine wheel of a sector-divided dual volute turbocharger, particularly a turbocharger where the tongue-to-blade gap is as small as from 1-3% of the wheel diameter, is reduced, and energy extraction is optimized, using a turbine wheel with (blade stiffness/backwall stiffness×100) between 41 and 44.
