Abstract:
1. An arrangement for recirculation of exhaust gases of a supercharged combustion engine, the arrangement comprising: an exhaust line configured to lead exhaust gases out from the combustion engine; an inlet line configured to lead air from a compressor to a first EGR cooler and then from the first EGR cooler to the combustion engine; the compressor configured to compress the air in the inlet line to above atmospheric pressure, and a return line which connects the exhaust line to the inlet line so that the return line recirculates exhaust gases from the exhaust line to the inlet line; the first EGR cooler positioned at the inlet line and configured to cool the recirculating exhaust gases in the return line using the air in the inlet line; and a second EGR cooler positioned at the inlet line and configured to cool the recirculating exhaust gases in the return line after the recirculating exhaust gases in the return line have been cooled in the first EGR cooler.
