Inlet channel system

An inlet passage system includes a split volute turbocharger having a variable turbine geometry (VTG). The turbocharger includes a turbine housing, a first volute and a second volute separated by a wall having a first tongue and a second tongue, and a turbine housing outlet. The system also includes a turbine wheel disposed in the turbine housing and an impeller ring disposed in the turbine housing between the turbine wheel and the volute. The system includes one or more VTG components and/or design modifications in the position of these components to manipulate aerodynamic and/or subsequent mechanical loads in the VTG mechanism of the inlet channel system to mitigate wear of the VTG components during normal use. 一种入口通道系统包括具有可变涡轮机几何形状(VTG)的分开式蜗壳涡轮增压器。该涡轮增压器包括涡轮机壳体，由具有第一舌状件和第二舌状件的壁分开的第一蜗壳和第二蜗壳，以及涡轮机壳体出口。该系统还包括被布置在该涡轮机壳体中的涡轮机轮以及被布置在该涡轮机壳体中在该涡轮机轮与蜗壳之间的叶轮环。该系统包括一个或多个VTG部件和/或这些部件的位置的设计修改，以操纵入口通道系统的VTG机构中的空气动力和/或随后的机械负载，从而减轻VTG部件在正常使用期间的磨损。
