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 to the combustion engine, a compressor adapted to compressing the air in the inlet line to above atmospheric pressure, and return line which connects the exhaust line to the inlet line. The arrangement comprises an 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 upstream of the compressor with respect to the direction of flow of the air in the inlet line.
