Claims (1)
を形成し、一方の給気ポートを内周面が螺旋状に形成さ
れてシリンダ内に旋回流を半じさせるヘリカリポートと
し、他方の給気ポートを前記旋回流の旋回方向と順方向
に吸入空気を前記シリンダ内に流出させるダイレクトポ
ートとしたことを特徴とする直接噴射式ディーゼルエン
ジンの給気ポート装置。Two air supply ports are arranged on the cylinder head in two stages, upper and lower. One of the air supply ports is a helical port whose inner circumferential surface is formed in a spiral shape to half-stir the swirling flow inside the cylinder, and the other An air intake port device for a direct injection diesel engine, characterized in that the air intake port is a direct port that allows intake air to flow out into the cylinder in a forward direction of the swirling direction of the swirling flow.
