<p>Cylinder intake charge swirl is accentuated by selectively directing gas flow past swirl-generating vanes (31) in the intake port (19) which are closest to the cylinder wall and reducing the gas flow past swirl-generating vanes (31) 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 (3,4,5,6) furthest from the cylinder wall and to encourage flow through swirl-directed passages (1,2,7,8) closer to the cylinder wall.</p> |
