Abstract

An inlet conduit is provided for a valve-controlled internal combustion engine, and also provided is a method for producing a flow deflection edge in an inlet conduit. In the region where the supply passage portion and the valve end passage portion of the inlet conduit meet, a cylindrical rod is guided through the cylinder head of the internal combustion engine. Portions of the peripheral surface of the rod form portions of the passage wall of the inlet conduit.
