Abstract:
(EN) In this engine, a main shaft 67 is arranged so that an angle θ1 < an angle θ2. In other words, the main shaft 67 is arranged near a virtual half-line Lh having a crankshaft center C61 at the end thereof so as to satisfy the abovementioned angular relationship, and the concentration of mass is thereby achieved. As a result, it possible to concentrate mass in an engine 5 provided with the main shaft 67, a crankshaft 61, and a balancer shaft 63.
(FR) Dans ce moteur, un arbre principal (67) est agencé de telle sorte qu'un angle θ1 est < à un angle θ2. En d'autres termes, l'arbre principal (67) est agencé à proximité d'une demi-ligne virtuelle Lh ayant un centre de vilebrequin C61 au niveau de son extrémité de façon à satisfaire la relation angulaire précitée, et la concentration de masse est ainsi obtenue. Par conséquent, il est possible de concentrer une masse dans un moteur (5) pourvu de l'arbre principal (67), d'un vilebrequin (61) et d'un arbre d'équilibrage (63).
(JA) 角度θ1<角度θ2を満たすように、メイン軸67が配置されている。つまり、この角度関係を満たすように、クランク軸心C61を端とする仮想半直線Lhにメイン軸67を近づけて配置して、マスの集中を図っている。これによって、メイン軸67、クランク軸61およびバランサ軸63を備えたエンジン5において、マスの集中を図ることが可能となっている。
