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: A turbocharger includes a turbine wheel rotatable about an axis and a turbine housing disposed about the turbine wheel. The turbine housing has an inlet portion defining a turbine housing inlet and has a volute portion defining a turbine housing interior. The volute portion has a first volute wall, a second volute wall spaced from the first volute wall, and a tongue separating the turbine housing inlet and the turbine housing interior. The tongue has a first tongue portion extending from the first volute wall substantially toward the second volute wall along the axis, a second tongue portion extending from the first tongue portion substantially circumferentially about the axis, and a third tongue portion extending from the second tongue portion substantially toward the second volute wall along the axis to reduce high cycle fatigue of the turbine wheel.

Abstract: In accordance with one aspect of the present disclosure, a turbocharger includes a compressor having a compressor wheel, a turbine provided within a housing, and an exhaust gas recirculation (EGR) flow path. The EGR flow path includes a first fluid connection in the housing and located in proximity to the turbine, a second fluid connection located in proximity to a trailing edge of the compressor wheel, an EGR control valve disposed between the first fluid connection and the second fluid connection, the EGR control valve configured to selectively operate the turbocharger in a low-heat mode having an EGR up to 50% and an operational mode having an EGR rate typically less than 35%.

Abstract: A system includes a divided volute turbocharger that delivers compressed air to an internal combustion engine and receives exhaust gas from the internal combustion engine. The turbocharger includes a turbine housing, a first and second volute, and a turbine housing outlet. The system also includes 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 vanes having an asymmetric vane pattern disposed on a vane ring surface of an annular disk that receives the turbine wheel therewithin to direct and control the flow of exhaust from the volutes into the turbine wheel with generally equal flow while significantly reducing HCF forcing function.
