An arrangement for recirculation of exhaust gases of a supercharged combustion engine. A return line which connects an engine exhaust line to an air inlet line for air supply to the combustion engine, to recirculate exhaust gases via the return line. A first EGR cooler in which the recirculating exhaust gases in the return line are cooled, as a first step, by a first coolant in a first cooling system. A second EGR cooler in which the recirculating exhaust gases in the return line are cooled, as a second step, by a second coolant in a second cooling system, and the second coolant is adapted to be at a temperature substantially corresponding to the temperature of the ambient surroundings when it is led into the second EGR cooler. A charge air cooler for the inlet line, a radiator for the second cooling system to cool the exhaust gases and a radiator element for cooling the second coolant. |
