| description | To provide an internal combustion engine that easily promotes mixing of spray and air.SOLUTION: An internal combustion engine comprises: a cylinder head; and a cavity formed in a top surface of a piston, and forming a combustion chamber between itself and the cylinder head. The cavity comprises: a first surface arranged in a top surface center part of the piston; a second surface arranged around the first surface, and arranged closer to the side of the cylinder head than the first surface; a groove part provided in the second surface, and recessed toward the side of the first surface; and a lid part covering the groove part on the side of the cylinder head, and separating a first space formed in the groove part, and a second space formed above the groove part. The lid part includes a slit connecting the first space and the second space.SELECTED DRAWING: Figure 3
【課題】噴霧と空気の混合を促進しやすい内燃機関を提供する。【解決手段】内燃機関は、シリンダヘッドと、ピストンの頂面に形成され、シリンダヘッドとの間に燃焼室を形成するキャビティと、を備え、キャビティは、ピストンの頂面中央部に配置される第１面と、第１面の周囲に配置され、第１面よりもシリンダヘッド側に配置される第２面と、第２面に設けられ第１面側に向けて凹んだ溝部と、溝部のシリンダヘッド側を覆い、溝部内に形成される第１空間と、溝部の上部に形成される第２空間とを隔てる蓋部を有し、蓋部は、第１空間と第２空間とを接続するスリットを含む。【選択図】 図３ |
