A turbocharger includes a center housing that includes a through bore and a stepped locating pin socket that includes a stop surface; a bearing disposed in the through bore where the bearing includes an opening; and a stepped locating pin where the stepped locating pin includes a pin portion received in part by the opening of the bearing and a seating portion secured via an interference fit in the stepped locating pin socket where a maximum radius of the seating portion exceeds a maximum radius of the pin portion and where the stepped locating pin includes a stop surface that contacts the stop surface of the stepped locating pin socket to axially position the stepped locating pin in the stepped locating pin socket.

Turbocharger assembly

An e-charger includes an outer housing and a rotor supported for rotation within the outer housing. A motor assembly is housed within the outer housing and includes an electric motor and a motor case. The electric motor is encased within the motor case. The electric motor is configured to drivingly rotate the rotor within the outer housing. Furthermore, the e-charger includes a cooling system configured to receive a coolant. The cooling system includes a manifold passage defined in the outer housing. The cooling system includes a first motor cooling circuit and a second motor cooling circuit that are cooperatively defined by the outer housing and the motor case. The first motor cooling circuit and the second motor cooling circuit are fluidly connected to the manifold passage. The manifold passage is configured to distribute a flow of the coolant between the first motor cooling circuit and the second motor cooling circuit.

A turbine housing assembly seal can include a cylindrical portion that defines an opening having an axis where the cylindrical portion is disposed at a cylinder radius from the axis; a lower edge disposed at a lower edge radius that exceeds the cylinder radius; an sloped annular portion that extends radially inwardly from the lower edge; a lower bend that extends from the sloped annular portion to a lower axial position of the cylindrical portion; an upper bend that extends from an upper axial position of the cylindrical portion; and an upper edge that extends radially outwardly from the upper bend to an upper edge radius that exceeds the cylinder radius and that is less than the lower edge radius.

Turbine exhaust seal

A turbine assembly can include a turbine wheel, a shroud component, a turbine housing and a seal that includes a wall and a lower lip that that extends radially outwardly from the wall where the seal is disposed, at least in part, between an outer surface of the shroud component and an inner surface of the turbine housing and where the lower lip is in contact with the turbine housing.

Turbine exhaust housing

An assembly can include a turbine wheel; a turbine housing that includes a lower turbine housing surface that extends from an exhaust volute to a cylindrical surface that defines an upper portion of a turbine wheel space; a shroud component that includes a contoured surface disposed between an inner end of an upper shroud component surface and an inner end of a lower shroud component surface where the contoured surface defines a lower portion of a turbine wheel space; and a seal mechanism where the turbine housing and the shroud component form an axial gap between a lower axial position of the cylindrical surface and an upper axial position of the contoured surface where the axial gap is axially positioned between an axial position of an inducer portion of the turbine wheel and an axial position of an exducer portion of the turbine wheel.

Exhaust turbine assembly

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.

A turbine assembly for a turbocharger can include a C-shaped seal that includes an inner diameter, an outer diameter, an axis aligned parallel to a rotational axis of a turbine wheel, a lower lip that contacts a lower axial face of an outer surface of a shroud component along an annular portion of the shroud component, an upper lip that contacts a lower axial face of an inner surface of a turbine housing, and a wall portion that extends between the lower lip and the upper lip. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

A turbine assembly can include a turbine wheel, a shroud component, a turbine housing and a seal that includes a wall and a lower lip that that extends radially outwardly from the wall at an obtuse angle where the seal is disposed, at least in part, between an outer surface of the shroud component and an inner surface of the turbine housing. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
