Abstract

The arrangement for feedback of exhaust gas into an internal combustion engine involves a venturi device (9) with a fixed venturi housing (14) for feeding exhaust gas into the engine inlet conduit (2), where together with the engine inlet air it is feed to the engine itself. The venturi device incorporates a sealing component for at least partly sealing between the venturi housing and the venturi insert (10) to obviate gas flow through a gap between the venturi insert and the venturi housing.
