Patent ID: 8261549

Claim:
An arrangement for recirculation of exhaust gases of a supercharged combustion engine block, the arrangement comprising: an exhaust line configured and operative to lead exhaust gases out from the combustion engine; an inlet line configured and operative to lead air to the combustion engine, the inlet line comprising a first inlet line portion having a beginning at a vehicle fresh air intake point and terminating at a compressor, the first inlet line portion positioned upstream of the compressor with respect to the direction of flow of the air in the inlet line; the compressor configured and operative to compress the air in the inlet line to above atmospheric pressure; a return line which connects the exhaust line to the inlet line, the return line being configured and operative to recirculate exhaust gases from the exhaust line to the inlet line; a first Exhaust Gas Recirculation (EGR) cooler configured and operative to subject the recirculating exhaust gases in the return line to a first step of cooling by a liquid coolant flowing through the combustion engine block; and a second EGR cooler configured and operative to cool the recirculated exhaust gases in the return line by the air in the first inlet line portion of the inlet line.
