り、さらに下流に存する流れガイドでも絞りながら吸気
弁軸回りに旋回して流動する吊り金型渦室部を形成した
ものにおいて、上記流れガイドと渦室部内壁との間に存
する上記スワールポート首部の吸気流通断面積を増減し
て平均スワール比を調整しうるように構成したことを特
徴とする直噴式ディーゼル機関の吸気ポート構造。The above-mentioned flow is created by forming a suspended mold vortex chamber in which the earth wall is low and the port cross-sectional area is small to reduce the intake flow rate, and the flow guide located downstream is also throttled while swirling around the intake valve axis and flowing. An intake port structure for a direct injection diesel engine, characterized in that the average swirl ratio can be adjusted by increasing or decreasing the intake air flow cross-sectional area of the swirl port neck existing between the guide and the inner wall of the swirl chamber.
