    • An internal combustion engine with dry sump lubricating system includes a feed pump which supplies lubricating oil from a lubricating oil tank disposed outside an engine body to all moving parts in the engine. After circulating through the engine, the lubricating oil drops down into a crank chamber and is immediately picked up from the crank chamber and sent back into the lubricating oil tank by a recovery pump. Since the lubricating oil tank is attached to an end of the engine body from which a crankshaft project, it does not increase the overall width (dimension in the direction perpendicular to the axis of the crankshaft) and height of the engine. Even when the engine has inclined cylinders, the lubricating oil tank can avail a high degree of design freedom because the end face is not influenced by inclination of the cylinders as greatly as side surfaces of the engine body. The engine also includes a breather system so designed as to prevent an operation failure of the engine which would otherwise be caused due to inflow of the lubricating oil into an intake system of the engine.
    • 具有干式油底壳润滑系统的内燃机包括供给泵,其将设置在发动机外部的润滑油箱的润滑油供给到发动机中的所有运动部件。 在通过发动机循环后,润滑油下降到曲柄室中,并立即从曲柄室拾起并通过回收泵送回润滑油箱。 由于润滑油箱安装在发动机主体的从曲轴突出的端部,所以不增加总体宽度(与曲轴的轴线垂直的方向的尺寸)和发动机的高度。 即使发动机具有倾斜气缸,润滑油箱也可以具有高度的设计自由度,因为端面不受发动机主体侧表面极大的气缸倾斜的影响。 发动机还包括通气系统,其被设计成防止由于润滑油流入发动机的进气系统而引起的发动机的操作故障。

    • A small-sized boat of the present invention includes a plurality of diaphragm type carburetors corresponding to each cylinder of a multicylinder engine. A crankshaft axis extends along a line extending through a bow and a stern of a hull. The carburetors include a plurality of shafts for throttle valves extending vertically in correspondence thereto, one throttle link connected to upper parts of the shafts for the throttle valves, and a plurality of diaphragm mechanisms having operating surfaces perpendicular to the crankshaft axis. By linking a plurality of the carburetors together to form an assembly of the carburetors, an overall size of carburetors is made small. Therefore, each carburetor can be mounted in a small engine room in correspondence to each cylinder of the engine.
    • 本发明的小型船包括对应于多缸发动机的每个气缸的多个隔膜式化油器。 曲轴轴线沿着延伸穿过船体的船首和船尾的线延伸。 化油器包括多个用于对应于其垂直延伸的节流阀的轴,一个连接到用于节流阀的轴的上部的节气门连杆,以及具有垂直于曲轴轴线的操作表面的多个隔膜机构。 通过将多个化油器连接在一起以形成化油器的组件,使化油器的总体尺寸变小。 因此,每个化油器可以安装在与发动机的每个气缸相对应的小型发动机室中。
