Abstract

L'invention concerne un moteur-générateur dans lequel l'arbre rotatif (361) d'un ventilateur (360) de radiateur est directement relié à un vilebrequin (305). Cette configuration rend inutile une courroie de ventilateur et supprime le besoin du remplacement périodique de la courroie de ventilateur, étendant l'intervalle entre les entretiens. En outre, une partie située plus haut que la section la plus élevée de la chemise d'eau d'une culasse se trouve sur une base (900) de radiateur pour supporter un radiateur (330), et un bouchon de remplissage (390) pour ouvrir et fermer un conduit de ravitaillement (380) relié au radiateur (330) est prévu sur la partie. En conséquence, l'eau peut être apportée par retrait du bouchon de remplissage (390). Ceci signifie que la liaison directe de l'arbre rotatif (361) du ventilateur (360) de radiateur au vilebrequin (305) permet l'alimentation en eau même si la hauteur de l'extrémité supérieure du radiateur (330) est réduite.
