摘要

A device of a system for air ducting of an internal combustion engine in a motor vehicle with a turbocharger arranged between an exhaust gas line and an intake line. The device includes a high pressure flow pathway with a valve branching from the exhaust gas line between the internal combustion engine and a turbine side of the turbocharger, a low pressure flow pathway with a valve branching in the flow direction of the exhaust gas downstream from the turbine side of the turbocharger, and an exhaust gas heat exchanger. A first flow pathway with a valve and a second flow pathway with a valve merge into a mouth region with a third flow pathway. At least one section of the high pressure flow pathway, the low pressure flow pathway, the flow pathways, and the exhaust gas heat exchanger are integrated inside a housing formed as a continuous compact unit.

1. An air ducting device for air ducting of an internal combustion engine in a motor vehicle having a turbocharger arranged between an exhaust gas line for the expansion of exhaust gas exiting the internal combustion engine and an intake line for compression of intake air to be delivered to the internal combustion engine, the device comprising:
a housing; a high pressure flow pathway with a first valve, the high pressure flow pathway branching from the exhaust gas line between the internal combustion engine and a turbine side of the turbocharger; a low pressure flow pathway with a second valve, the low pressure flow pathway branching from the exhaust gas line downstream from the turbine side of the turbocharger in a flow direction of the exhaust gas; a first flow pathway branching from the intake line upstream of a compressor side of the turbocharger in a flow direction of the intake air; a second flow pathway having a third valve; a third flow pathway having a fourth valve, the second flow pathway and the third flow pathway merging in a mouth region of the first flow pathway; and an exhaust gas heat exchanger, wherein at least a portion of each of the high pressure flow pathway, the low pressure flow pathway, the first flow pathway, the second flow pathway, the third flow pathway, and the exhaust gas heat exchanger is integrated within the housing.
