Multi-cylinder engine air intake system slots air feedtube possibly severally normal to tube axis right along parallel to air manifold so slots face air inlet tube entries.

摘要

The air feedtube (10) is slotted out (11) normal to its long axis (L) and the air manifold (2) is of the long type and runs right along the tube axis (L) and parallel to this. Several outlet slots (12) can be placed along the tube (10) so each faces an inlet tube (20) entry (22). The tube (10) is fixed to the manifold inwall at the valves and tapers in the air feed direction within the manifold.
