射する直接噴射式内燃機関において、上記燃焼室
の上記ピストン上面への開口部と底面との形状を
それぞれ同数の円弧状の線分を辺とし同辺よりも
小径の円弧状の線分を上記各辺を接続する隅角部
として、底面の多辺形よりも、小さくした多辺形
状に形成すると共に、上記開口部と底面とは周方
向に偏位して配置されたことを特徴とする内燃機
関の燃焼室。 In a direct injection internal combustion engine that injects fuel into a combustion chamber recessed in the top surface of the piston, the shape of the opening of the combustion chamber to the top surface of the piston and the bottom surface are the same, with the same number of arcuate line segments as sides. An arc-shaped line segment with a smaller diameter than the sides is used as a corner connecting each of the sides, forming a polygon shape smaller than the polygon of the bottom surface, and the opening and the bottom surface are arranged in the circumferential direction. A combustion chamber of an internal combustion engine characterized by being arranged offset.
