Patent
CA 2273255
A subtank (89) provided on a side wall of an engine block on an outboard motor temporarily stores a fuel supplied from a fuel tank not shown and provided on a hull, and pressurizes the fuel to a high pressure to deliver it to a fuel injection valve (94). An upper space in the subtank (89) is connected to an inner space of an intake silencer (76) through two air vent pipes (L7, L8 ). Even when a fuel vapor liquefies in the intake silencer (76) at the time of engine suspension, the liquefied fuel is caught at a bottom of the intake silencer (76) having a large volume with no possibility of flowing out.
Un réservoir auxiliaire (89) monté sur l'un des côtés du bloc moteur d'un moteur hors bord emmagasine temporairement du carburant provenant d'un réservoir non montré placé sur la coque, et met le carburant sous pression pour le fournir à une soupape d'injection (94). L'espace supérieur du réservoir auxiliaire (89) est relié à un espace intérieur d'un silencieux d'admission (76) par l'intermédiaire de tubes évents (L7, L8). Même lorsque les vapeurs de carburant se liquéfient dans le silencieux (76), lors d'un arrêt du moteur, le carburant liquéfié est retenu à la base du silencieux (76) d'admission où il dispose d'un important volume, sans pouvoir s'échapper.
