カル吸気ポート。an inlet portion connected to the intake manifold and an outlet portion opening into the combustion chamber in a direction substantially perpendicular to the inlet portion; A bulging portion is provided that bulges toward the intake valve, and the bulging portion extends around the axis of the intake valve to form a turning passage therearound. The opposing portion is connected to the intake air flow that has collided with the opposing portion through the swirl passage.
The wall of the inlet section, which is continuous with the root of the bulge, is inclined to provide a velocity component toward the opening end and a velocity component directly toward the opening end, and the wall portion of the inlet section that is continuous with the root of the bulge section has a wall section that allows the intake air flowing through the inlet section to flow toward the opening end. What is claimed is: 1. A helical intake port for an internal combustion engine, characterized in that it is provided with an inclined surface section that is inclined to provide a direct velocity component.
