ABSTRACT:
An internal combustion engine is disclosed having an apparatus which operates to induce cylinder charge swirl across the range of valve lift and volumetric flow. The intake system of the present invention includes a cylinder-disposed chamber shroud which extends circumferentially about a portion of the intake valve opening in the combustion chamber. The shroud operates to preferentially direct intake charge flowing into the combustion chamber to one side of the cylinder thereby inducing charge swirl. A port guide wing, disposed upstream of the intake valve opening within the intake port supplying charge to the combustion chamber, directs inlet charge to one side of the intake port under high flow conditions. The flow entering the combustion chamber primarily through one side of the valve opening induces swirl within the cylinder.
