INTAKE PATH GAS INTRODUCING STRUCTURE AND INTAKE MANIFOLD

摘要

PROBLEM TO BE SOLVED: To provide an intake path gas introducing structure which can easily discharge condensate and an intake path gas introducing structure and an intake manifold which can uniformly distribute gas between cylinders and uniformly diffuse gas to an intake.

SOLUTION: An intake path 4 is formed by connecting an intake branch pipe 6b of the intake manifold 2 to an intake port 22 at connecting end faces 20. An exhaust gas introducing path 12 is introduced to the intake branch pipe 6b. An end of the exhaust gas introducing path 12 opened to the intake path 4 is formed to protrude to the intake path 4. An end face 12c of the exhaust gas introducing path 12 has a central side of the intake path of the end face 12c inclined to a direction more reverse to a direction of an intake flow than the connecting end face 20 and inclined to a direction more reverse to the direction of the intake flow than a position orthogonal to an axis of the exhaust gas introducing path 12 itself.
