上にピストンの軸線方向に隣接配置された複数個
の断面円弧状凹状燃料反射面を形成して燃料噴射
弁から各凹状燃料反射面に向けて順次燃料を噴射
させ、各凹状燃料反射面の形成位置および断面形
状を各凹状燃料反射面において反射した噴射燃料
がピストンの上昇に伴つてキヤビテイ周辺部から

直噴式デイーゼル機関の燃焼室。 A plurality of concave fuel reflecting surfaces each having an arcuate cross section are formed adjacent to each other in the axial direction of the piston on the inner circumferential wall surface of the cavity formed on the top surface of the piston, and fuel is sequentially directed from the fuel injector toward each of the concave fuel reflecting surfaces. A direct injection type in which the formation position and cross-sectional shape of each concave fuel reflecting surface are determined so that the injected fuel reflected at each concave fuel reflecting surface moves sequentially from the cavity periphery to the cavity center as the piston rises. Combustion chamber of a diesel engine.
