Abstract:
(EN) Provided is an engine in which a crankshaft 61 is positioned further toward one side Do1 than the center line Lc of a cylinder 511 and a space is thereby maintained on the other side Do2 of the center line Lc of the cylinder 511. In addition, the space is used effectively by arranging the upper end 55T of a reservoir section 55 on the other side Do2 of the center line Lc of the cylinder 511 so as to overlap with the crankshaft 61 when viewed from an offset direction Do. As a result, it is possible to maintain a wide engine oil storage volume while minimizing increases in the size of the engine 5.
(FR) L'invention concerne un moteur dans lequel un vilebrequin (61) est positionné plus loin vers un côté Do1 que la ligne centrale Lc d'un cylindre (511) et par ce moyen un espace est maintenu sur l'autre côté Do2 de la ligne centrale Lc du cylindre (511). De plus, l'espace est utilisé efficacement en agençant l'extrémité supérieure (55T) d'une section de réservoir (55) sur l'autre côté Do2 de la ligne centrale Lc du cylindre (511) de façon à chevaucher le vilebrequin (61) lorsqu'il est vu depuis une direction de décalage Do. Par conséquent, il est possible de maintenir large un volume de stockage d'huile moteur tout en réduisant au minimum les augmentations de la taille du moteur (5).
(JA) クランク軸61をシリンダー511の中心線Lcより一方側Do1に位置させることで、シリンダー511の中心線Lcの他方側Do2にスペースを確保している。そして、貯留部55の上端部55Tを、オフセット方向Doから見てクランク軸61に重なるようにシリンダー511の中心線Lcの他方側Do2に配置して、このスペースを有効活用している。これによって、エンジンオイルの貯留容積を広く確保しつつエンジン5の大型化を抑制することが可能となっている。
