A passage for supplying a gaseous fuel component, such as air, to the cylinder of an internal combustion engine in which the gaseous component is caused to take on a rotating movement prior to entry thereof into the cylinder. The passage has a curved section at the upstream end and at the downstream end has a cylindrical section which is provided with a valve. Between the curved upstream section and the cylindrical downstream section there is a helical section. The gaseous component is caused to rotate about the axis of the helical section and, therefore, to enter the cylinder in a turbulent, rotating, condition. Inlet and outlet passages are the same and at least similar with respect to the foregoing passage characteristics. |
