ている内燃機関のピストンであつて、前記空洞部
入口内周面に、前記空洞部内に入る空気流に乱れ
を発生させる突片を内側へ向かつて一体的に設け
たことを特徴とする内燃機関のピストン。 A piston for an internal combustion engine in which a cavity is formed inside by being hollowed out from the lower surface side, and a protrusion that causes turbulence in the air flow entering the cavity is provided on the inner circumferential surface of the entrance of the cavity, and is directed inward. The piston of an internal combustion engine was once characterized by being provided integrally.
