Abstract
An engine with a cylinder inlet port controlled by a poppet valve has a flow directing vane on a shaft aligned with the valve stem upstream in the direction of flow. The vane is movable between a position aligned with the valve stem in which free flow is allowed and an angled position of less than 90.degree. to one side of the port whereby maximum charge swirl is obtained in the cylinder.
