摘要： A turbocharger assembly includes a compressor assembly, a turbine wheel, a shaft, a bearing assembly, and a cooling gas conduit. The compressor assembly includes a compressor impeller. The compressor impeller includes an outermost impeller edge and has a maximum cross-sectional dimension at the outermost impeller edge. The shaft interconnects the compressor impeller and the turbine wheel. The bearing assembly surrounds at least a portion of the shaft. The cooling gas conduit is disposed in fluid communication with the compressor assembly and the bearing assembly. At least a portion of the cooling gas conduit is disposed adjacent the outermost impeller edge such that the cooling gas conduit is configured to receive a portion of intake gases flowing along the outermost impeller edge and guide the portion of the intake gases toward the bearing assembly to cool the bearing assembly.

摘要： A turbocharger for an internal combustion engine includes a rotating assembly having a turbine wheel disposed inside a turbine housing and a compressor wheel disposed inside a compressor cover. The turbine housing defines a turbine outlet cavity, a turbine housing inlet, and a turbine housing outlet. The turbine housing inlet is configured to channel engine post-combustion gases to the turbine wheel and the turbine housing outlet is configured to exhaust the gases aft of the turbine wheel. A diffuser arranged inside the turbine outlet cavity is configured to channel the post-combustion gases aft of the turbine wheel and out to the turbine housing outlet, without discharging into the turbine outlet cavity.

摘要： A turbocharger includes a turbine housing defining a turbine chamber and a compressor housing defining a compressor chamber. A turbine wheel is disposed in the turbine chamber and a turbine shaft is connected to the turbine wheel. A compressor wheel is disposed in the compressor chamber and connected to the turbine shaft. A compressor back plate is adjacent to the compressor wheel and a bearing cartridge is sandwiched directly between the compressor back plate and the turbine housing and rotatably supporting the turbine shaft.
