Claims (1)
- 気筒上部周囲に配置された燃料噴射弁により燃料を噴射して均質混合気を形成する筒内噴射式火花点火内燃機関において、前記燃料噴射弁は、主には幅方向に広がる扇状燃料噴霧を、前記扇状燃料噴霧の厚さ方向中心平面が気筒中心軸線と略平行となるように吸気行程後半の気筒内全体に噴射し、前記扇状燃料噴霧の上部は、前記扇状燃料噴霧の下部に比較して貫徹力が弱められ、前記燃料噴射弁は、前記扇状燃料噴霧を噴射するために上下方向に配列された多数の小径噴孔を具備し、上側の小径噴孔群の孔径が下側の小径噴孔群の孔径より小さいか、又は、上側の小径噴孔群の孔数が下側の小径噴孔群の孔数より少ないことを特徴とする筒内噴射式火花点火内燃機関。
