Device for supporting a supercharging device

摘要

A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit.

主权项

1. A device for utilizing the waste heat of an internal combustion engine, comprising:
a single-stage or multi-stage supercharging device; and an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, the additional supercharging device being connected to the single-stage or multi-stage supercharging device; wherein an exhaust-gas recirculation system downstream from a branch point is assigned a first heat exchanger, which removes heat from exhaust gas of the internal combustion engine and adds the heat to steam of the auxiliary circuit upstream from the additional supercharging device.
