する内燃機関の吸気マニホルド。In an intake manifold for an internal combustion engine, which is comprised of a riser part, a curved passage part on both sides of the riser part, and a branch port that communicates the curved passage part with an intake port of the cylinder head, the extension line of the outer peripheral wall of the curved passage part is the cylinder head. A separator is formed so as to intersect at the sides, and a separator is protruded from the lower surface of the branch port and the curved passage part, and the separator starts near the port branch point and extends toward the curved passage part, and the separator is aligned with the center line of the manifold. On the other hand, Seha L/
- An intake manifold for an internal combustion engine, characterized in that the intake manifold is inclined so that the tip of the intake manifold faces inward.
