Movable aerodynamic device for e.g. four stroke combustion engine, steers air flow strongly to channel wall, so that air flow is conducted tangentially into valve area and swirl is produced in cylinder, and accelerates air flow
摘要
<p>The device (6) is supported at a channel wall and continuously changes a turbulence swirl in each operating point of a combustion engine by using an external drive. The device steers an air flow strongly to the channel wall, so that the air flow is conducted tangentially into a valve area and the swirl is produced in a cylinder. The device accelerates the air flow by a nozzle shaped narrowing of the inlet channel.</p>
