Abstract
An internal combustion engine exhaust gas system includes an EGR arrangement adapted to lead a first flow of exhaust gas, the EGR flow, from an outlet side of the engine to an inlet side of the engine, an exhaust gas conduit adapted to lead away a second flow of exhaust gas, the exhaust flow, from the outlet side of the engine, and an energy recovering unit, such as a turbo, associated with the exhaust gas conduit. The unit is adapted to recover exhaust gas energy from the exhaust flow. The system includes a heat exchanger adapted to allow heat exchange between at least a part of the EGR flow and at least a part of the exhaust flow, the heat exchanger being associated with the exhaust gas conduit at a position downstream the energy recovering unit.
