Abstract
A method and a device for exhaust gas recycling (EGR) in a combustion engine (1), wherein EGR gases are led into a section of the intake channel where a venturi (9) is arranged for modifying the flow of the intake air, and where a reduced pressure prevails because of modified flow, wherein at least a portion of the wall (10) of the venturi (9) is adjustable for varying the cross section of the venture and thereby for desired adjustment to prevailing operational conditions.
