Abstract
An arrangement for cooling of recirculating exhaust gases of a combustion engine () in a vehicle (). The arrangement comprises a first EGR cooler (), a driving means () adapted to driving air through the first EGR cooler () in order to cool the exhaust gases in a return line () which are subjected to a first step of cooling in the first EGR cooler (), and at least one second EGR cooler () in which the exhaust gases in the return line () are intended to undergo a second step of cooling. The arrangement comprises an air line () which extends at least from the first EGR cooler () to the exhaust pipe () at a location between the turbine () and the exhaust-treating component (), which air line () is adapted to leading warm air from the first EGR cooler () into the exhaust line () at said location.
