室を、該上部燃焼室の下面に断面積の比較的小さ
な下部燃焼室を夫々凹設し、機関低負荷運転時に
は前記下部燃焼室に向けて燃料を噴射し、機関高
負荷運転時には前記上部燃焼室と下部燃焼室とに
向けて燃料噴射する燃料噴射手段を前記上部燃焼
室と下部燃焼室とに臨むように設けた筒内燃料噴
射式内燃機関。 An upper combustion chamber with a relatively large cross-sectional area is formed on the top surface of the piston, and a lower combustion chamber with a relatively small cross-sectional area is formed on the lower surface of the upper combustion chamber. When the engine is operated at low load, fuel is directed toward the lower combustion chamber. A cylinder fuel injection type internal combustion engine is provided with a fuel injection means that faces the upper combustion chamber and the lower combustion chamber and injects the fuel toward the upper combustion chamber and the lower combustion chamber during high-load operation of the engine. .
