Embodiment Construction

[0030] figure 1 A device for exhaust gas conduction embodied as a turbocharger assembly 10 is shown. The turbocharger assembly 10 has a turbocharger 11 with a compressor 12 and a turbine 14 . The turbocharger assembly 10 additionally has an exhaust pipe 16 .

[0031] The compressor 12 is part of the intake system of an internal combustion engine (not shown). The compressor 12 includes a compressor housing 18 and a compressor wheel (not shown) rotatably disposed within the compressor housing 18 to compress intake air. Intake air flows into the compressor 12 at a compressor inlet 18A and is compressed therein by the compressor wheel. Compressed intake air exits the compressor 12 through a compressor outlet 18B. The compressor wheel is driven by a shaft which in turn is driven by the turbine wheel of the turbine 14 .

[0032] A turbine wheel of the turbine 14 is mounted rotatably in a turbine housing 20 . The turbine wheel is driven by hot exhaust gases that push the blades...

Abstract

The invention relates to a turbocharger assembly for an internal combustion engine and a motor vehicle having the assembly. The turbocharger assembly (10) has a turbocharger (11), wherein the turbocharger has a turbine housing (20). The turbocharger assembly (10) also has an exhaust pipe (16). The exhaust duct (16) is disposed downstream of the turbine housing (20). The exhaust pipe (16) has a diffuser region (22) and an exhaust manifold region (24).

Description

technical field [0001] The invention relates to a device for guiding the exhaust gas of an internal combustion engine, in particular a turbocharger assembly. The invention furthermore relates to a motor vehicle, in particular a commercial vehicle, having a turbocharger assembly. Background technique [0002] To increase the power or efficiency of an internal combustion engine, a turbocharger or an exhaust-gas turbocharger (ATL) can be employed. A turbocharger has an intake compressor and an exhaust turbine. The compressor is integrated in the intake system of the internal combustion engine to increase the air flow and reduce the suction work of the pistons of the internal combustion engine. The compressor of the turbocharger is driven by the exhaust turbine. In particular, the turbine wheel of the exhaust gas turbine drives the compressor wheel of the compressor by means of a shaft co-rotating with the turbine wheel. During operation, hot exhaust gas from the combustion ...
