Abstract

Disclosed is an intake pipe for a combustion engine, comprising a housing () with a supply duct () for especially compressed air, a heat exchanger () which is disposed within a main duct () in the housing () and through which the air can flow in order to exchange heat with a fluid, and a bypass duct () that is separated from the main duct () in at least some sections and is fitted with at least one positioning element () to allow the fed air to adjustably bypass the heat exchanger (). An end of the bypass duct () on the engine side is placed at a still flow-relevant short distance from an opening () of an intake valve () of the combustion engine.
