Abstract

Recirculated exhaust gases are fed into a section of the engine intake pipe (2) next to a section (8) that contains a wing part (9) for modifying the flow of incoming air, this part having a wing profile when viewed in the main flow direction of the pipe. The wing part is used to reduce pressure.
