Abstract
In an internal combustion engine which is provided with a throttle valve of the type which, when slightly opened, provides a flow of intake gases which is biased towards one particular side of the intake passage, a vane is provided, which particularly directs gases passing near that one particular side of the intake passage towards a portion of the edge of the inlet port which is most remote from the central axis of the power cylinder, whereby good swirl and turbulence are generated in the power cylinder, especially during low and medium load operation of the engine.
