    摘要： An outboard engine assembly for use on a boat has an engine mechanism including in an upper region thereof an engine having a substantially vertical crankshaft and a vertical array of substantially horizontal cylinders. The engine mechanism is mounted on the stern of the boat by an attachment. The attachment includes a stern bracket adapted to be fixed to the stern of the boat, a swivel case supported on the stern bracket for vertical angular movement, a substantially vertical swivel shaft supported on the swivel case for horizontal angular movement, and a pair of upper and lower supports mounted on the swivel shaft and supporting the engine mechanism. The engine has joint members coupled to the upper support at a position between adjacent two crankshaft counterbalances which correspond to adjacent two cylinders, respectively, as viewed in side elevation, the joint members having respective portions located within a path of the two crankshaft counterbalances as viewed in plan. The engine mechanism also has a balancer mechanism mounted on a front wall of the engine for attenuating engine vibrations, and a fuel supply assembly mounted on an engine side wall.

    摘要： 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.

    摘要翻译： 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。

    摘要： 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.

    摘要： An extension case in which an oil pan is accommodated includes on its left and right side surfaces mount receiving recesses for receiving a pair of lower mounts, respectively, and further an oil drain recess on the right side surface to which a drain bolt is exposed for draining oil from the oil pan. The oil drain recess is formed upwardly of the right mount receiving recess with a partition wall interposed therebetween and these recesses are opened at the right side surface of the extension case. When the extension case is produced by casting with two die parts which are divided into left and right sides, the arrangement makes it possible to form both the recesses simultaneously with use of one of the die parts.

    摘要： In a V-type engine including first and second pistons connected to a common crank pin of a crankshaft through first and second connecting rods, a large end of each of the connecting rods is formed so that its lower surface assumes a substantially horizontal attitude at a most-lowered position of the crank pin. This ensures that even if the construction is such that the large ends of the conducting rods do not contact with a defined amount of oil stored in lower portion of a crankcase in the V-type engine, the lower portion of the crankcase can be formed at a small depth, thereby lowering the entire height of the V-type engine.
