  • TURBOCHARGER TURBINE HOUSING ASSEMBLY
    Publication number: 20260022655
    Abstract: A turbine housing assembly can include an inlet conduit portion that defines an inlet passage, where the inlet passage is in fluid communication with a cavity via an opening surrounded by a valve seat; a volute portion that defines a volute that is in fluid communication with the inlet passage and a turbine wheel space; a valve, where a shaft is rotatably supported by a bushing disposed in a bore and where, in a closed state of the valve, an arm is disposed in the cavity; and a controller operatively coupled to a control arm to transition the valve between the closed state and an open state, where, in the open state, a plug moves into the inlet passage to restrict flow between an inlet opening and a volute and to direct flow to the cavity, where the cavity is in fluid communication with a treatment unit.
