Title: Arrangement for recirculation of exhaust gases of a supercharged internal combustion engine

Abstract: An arrangement for recirculation of exhaust gases of a supercharged combustion engine in a vehicle. A first EGR cooler effects a first step of cooling the recirculating exhaust gases in the return line by means of a cooling medium in the form of a cooling air flow, and a second EGR cooler effects a second step of cooling the recirculating exhaust gases in the return line by means of a cooling medium which is at substantially the temperature of the surroundings. The first EGR cooler is fitted in an internal region of the vehicle which is adapted to have the cooling air flow passing through it during operation of the combustion engine.
