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 means (S<SUB>2</SUB>) arranged in the inlet line (6), a line (13) extending from the valve means (S<SUB>2</SUB>) to a connection point (9a) to the return line, which connection point (9a) is situated 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 means (S<SUB>2</SUB>) in a cleaning position so that at least part of the compressed air in the inlet line (6) is led via the valve means (S<SUB>2</SUB>) and said line (13) to the return line (9), whereby the air is led in such a direction that it flows through the EGR cooler (11).
