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.
A heat exchanger, comprising heat exchange surfaces arranged to allow heat exchange between a first, EGR flow of exhaust gas that flows from an outlet side of an internal combustion engine to an inlet side of the engine, and a second, exhaust flow of exhaust gas that flows from the outlet side of the engine so that the heat exchanger functions as an EGR cooler, wherein the EGR flow and the exhaust flow flow through first and second conduits through the heat exchanger, respectively, the first and second conduits having separate inlets into the heat exchanger.
