に沿つて配列された複数の開口部に夫々接続され
て出口通路を構成する複数のパイプ状ブランチ部
を備えてなる内燃機関の吸気コレクタにおいて、
前記開口部とブランチ部との接続部の境部のうち
吸気入口から長手方向に沿つて流れる吸気流を基
準として吸気上流側に位置する境部を大きなＲを
有する曲面に形成すると共に、吸気下流側に位置
する境部を小さなＲを有する曲面に形成したこと
を特徴とする内燃機関の吸気コレクタ。 In an intake collector for an internal combustion engine, the intake collector has an intake inlet at one end in the longitudinal direction, and includes a plurality of pipe-like branch parts each connected to a plurality of openings arranged along the longitudinal direction and forming an outlet passage. ,
Among the boundaries between the connection portions of the openings and the branch portions, the boundary portions located on the intake upstream side with respect to the intake flow flowing in the longitudinal direction from the intake inlet are formed into curved surfaces having a large radius, and An intake collector for an internal combustion engine, characterized in that a boundary portion located on the side is formed into a curved surface having a small radius.
