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, and which is provided with a helical type inlet port which has a helical surface leading to the combustion chamber which imparts swirl to inlet gases, a vane is provided, which particularly directs gases passing near that one particular side of the intake passage towards the start of the helical surface, whereby good swirl and turbulence are generated in the power cylinder, especially during low and medium load operation of the engine.
