APPARATUS AND METHOD FOR RETURNING EXHAUST GAS OF AN INTERNAL COMBUSTION ENGINE

摘要

An apparatus for returning exhaust gas of an internal combustion engine is provided. The apparatus includes a compressor that is driven by exhaust gas, wherein an exhaust-gas flow enters into the compressor on a high-pressure side and exits the compressor on a low-pressure side. A branch is provided on the high-pressure side with regard to the compressor for returned exhaust gas, and at least one exhaust-gas cooler is provided for transferring heat out of the branched-off exhaust-gas flow into a cooling medium. A heat exchanger is provided, via which heat can be transferred between the exhaust-gas flow, which branches off on the high-pressure side, and an exhaust-gas flow on the low-pressure side with regard to the compressor.
