- 燃焼室のほぼ中心に設けられる点火栓と、
二つの吸気弁を介して前記燃焼室に開口する吸気ポートと、
前記燃焼室の吸気ポートと相対する位置に二つの排気弁を介して開口する排気ポートと、
前記吸気ポートの下方に配設され、前記排気弁側に向けて燃料を噴射する噴射弁と、
前記燃焼室の中心より前記排気弁側へ偏った位置に凹部が設けられるピストンと、
を備える筒内直接噴射内燃機関であって、
前記凹部の最深部はピストン冠面中心より排気弁側に位置するとともに、当該最深部からピストン冠面中心より吸気弁側に設定された稜線に向けて当該凹部の曲面状の傾斜面が形成され、
前記燃焼室の上側を前記吸気弁側から前記排気弁側へ進み、前記燃焼室の前記排気弁側を下降し、前記燃焼室の下側を前記排気弁側から前記吸気弁側へ進み、前記燃焼室の前記吸気弁側を上昇するガス流動を前記凹部の上方に形成するとともに、
圧縮行程後半に前記噴射弁から噴射されて前記凹部に集中した燃料を前記ガス流動により前記傾斜面に沿って前記燃焼室の上部へ押し上げて前記点火栓の周辺まで輸送し当該点火栓の周辺に濃混合気を配するようにしたことを特徴とする筒内直接燃料噴射内燃機関。
