Abstract

The present invention relates to an arrangement and a method for recirculation of exhaust gases of a combustion engine (2). The arrangement comprises a return line (11), an EGR cooler device (14, 15) for cooling of recirculating exhaust gases which has an exhaust gas passage (14a, 15a) which comprises a first aperture (14b) and a second aperture (14c, 15b), and a cooling system which is adapted to cooling the recirculating exhaust gases in the EGR cooler device (14, 15) to the condensation temperature of the water vapour in the exhaust gases. The arrangement comprises a valve means (24) adapted to leading the recirculating exhaust gases alternately in opposite directions through the EGR cooler device (14, 15) so that condensate forms alternately within the exhaust gas passage (14a, 15a) of the EGR cooler device in the portion which comprises the first aperture (14b) and in the portion which comprises the second aperture (14c, 15b).
