ABSTRACT:
Cylinder intake charge swirl is accentuated by selectively directing flow past swirl generating vanes in the intake port which are closest to the cylinder wall and reducing the flow past swirl generating vanes furthest from the cylinder wall. This may be accomplished by utilizing asymmetrically variable swirl vanes arranged to reduce flow at lower engine loads through passages furthest from the cylinder wall and encourage flow through swirl directed passages closer to the cylinder wall.
