Abstract
In an injection-type internal-combustion engine with an air suction passage 2 designed as a twist forming passage means, the edge 10 between a curved passage section 4 and the valve chamber 6 is formed by an elastically deformable hollow body 12 located in a cavity 11. The interior of the hollow body 12 is in communication with a pressure means source 15, 16, by means of which the pressure in the hollow space is varied in dependence upon operating parameters. When pressurized the hollow body extends out of the cavity and effects a constriction of the air stream passing through passage 2 whereby the twist is increased.
