Abstract

The present invention relates to an arrangement and a method for recirculation of exhaust gases of a combustion engine (1). The arrangement comprises a valve device (V<SUB>1</SUB>, V<SUB>2</SUB>) arranged in the return line (9) upstream from the EGR cooler (11) with respect to the intended direction of exhaust gas flow in the return line (9), and a control unit (10) which in certain situations is adapted to placing the valve device (V<SUB>1</SUB>, V<SUB>2</SUB>) in a cleaning position in which a portion of the return line (9b) which comprises the EGR cooler (11) is connected to surrounding air (13) so that compressed air from the inlet line (6) flows through said portion of the return line (9b) and the EGR cooler (11) before it is led out to surrounding air (13) by means of the valve device (V<SUB>1</SUB>, V<SUB>2</SUB>).
