Abstract

An arrangement and a method for control of transfer of EGR gases in a turbocharged combustion engine (1), whereby exhaust gases are drawn off in a regulated manner via a draw-off valve (7) to drive an EGR pump (6) for creating an EGR transfer flow which is regulated by an EGR valve (10). Both the draw-off valve (7) and the EGR valve (10) are regulated by means of a single control valve (14), and the draw-off valve (7) responds to a control fluid pressure which is higher than the control fluid pressure to which the EGR valve (10) responds, causing the EGR valve (10) to open before the draw-off valve (7). The invention also relates to a diesel engine equiped with such an arrangement.
