ABSTRACT:
The present invention relates to an arrangement for recirculation of exhaust gases of a supercharged combustion engine. The arrangement comprises an exhaust line intended to lead exhaust gases out from the combustion engine, an inlet line intended to lead air which is at above atmospheric pressure to the combustion engine, a compressor adapted to the inlet line so that it is possible, via the return line, to recirculate exhaust gases from the exhaust line to the inlet line. The arrangement comprises a first EGR cooler in which the recirculating exhaust gases in the return line are cooled by the air in a portion of the inlet line which is situated downstream of the compressor in the inlet line with respect to the direction of flow of the air in the inlet line.
