Induction device for internal combustion engine has air drawn into induction passage with helically formed swirling motion, with rotational axis of vortex running parallel to induction passage

摘要

The induction device has a form designed in such a way that the drawn in air is guided into the induction passage (4) with a helically formed swirling motion (11), the rotational axis (12) of the created air vortex running parallel to the induction passage. The air swirling motion is generated before the place of fuel entry is reached.
