Claims (1)
接続されかつほぼまっすぐに延びる入口通路部とにより
構成されたヘリカル型吸気ポートにおいて、上記入口通
路部の一側壁面上に該−側壁面から入口通路部内に向け
てほぼ水平方向に突出する隔壁を形成して該隔壁により
入口通路部内を上下２層の上部通路と下部通路に分割し
、該下部通路内に開閉弁を設けて該開閉弁を機関低負荷
運転時に閉弁するようにしたヘリカル型吸気ポート。In a helical intake port configured with a spiral part formed on the side of the intake valve and an inlet passage part connected tangentially to the spiral part and extending almost straight, there is a spiral part on one side wall surface of the inlet passage part. A partition wall is formed that projects from the side wall surface into the inlet passageway in a substantially horizontal direction, and the partition wall divides the inside of the inlet passageway into an upper passageway and a lower passageway in two layers, upper and lower, and an on-off valve is provided in the lower passageway. A helical intake port is provided so that the opening/closing valve is closed during low engine load operation.
