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.
