A turbocharger includes a housing and a rotor with a shaft that is housed within the housing. The turbocharger also includes a bearing structure that supports rotation of the shaft within the housing and a locating fastener that retains the bearing structure in a position relative to the housing. Furthermore, the turbocharger includes a heating system coupled to the locating fastener and that is configured for selectively heating the locating fastener.

An assembly can include an exhaust gas turbine housing that includes an inner wall and an outer wall that define a first exhaust gas channel and a second exhaust gas channel to a turbine wheel space where the inner wall includes an inner wall end at the turbine wheel space and the outer wall includes an outer wall end at the turbine wheel space; a first adjustable divider vane disposed adjacent to the inner wall end; a second adjustable divider vane disposed adjacent to the outer wall end; and at least one set of adjustable variable geometry nozzle vanes that define nozzle throats that direct flow of exhaust gas from one of the exhaust gas channels to the turbine wheel space.

A turbocharger includes a variable turbine nozzle formed between first and second walls. A variable-vane assembly has a fixed nozzle ring and a plurality of circumferentially spaced vanes disposed in the nozzle and rotatably mounted on the nozzle ring such that the vanes are pivotable. The nozzle ring defines the first wall of the turbine nozzle, each vane having a first end adjacent the first wall and a second end adjacent the second wall. The second wall of the turbine nozzle is formed by a gas pressure-responsive member that is arranged to be axially movable relative to the vanes. A first stop is positioned so that the gas pressure-responsive member is urged against the first stop by a differential gas pressure exerted on the gas pressure-responsive member so that there is a non-zero first value for a clearance between the second ends of the vanes and the second wall of the turbine nozzle.
