摘要： A compact and lightweight outboard engine (1) mounted to a boat stern by a mounting device having a tilt shaft comprises: an engine (2) including a flywheel (56) positioned at a lower end portion of a vertically extending crankshaft, and an oil pan positioned below the flywheel (56). An upper wall of a flywheel chamber (59) accommodating the flywheel 56 is made up of a bottom wall of a crank chamber made of a crankcase (30), etc., and a bottom wall (30a) of the crankcase (30) forming a front portion of the engine body (3) has a return oil path 71 formed forward of an inner circumferential wall surface (60e) of a circumferential wall (60) of the flywheel chamber (59) and having inflow openings (71a, 71b) through which lubricant oil flows from the crank chamber. Such outboard engine prevents output loss by preventing or minimizing lubricant oil staying in the crank chamber while the engine is driven in a tilt-up condition.

摘要： An outboard engine comprises an engine having a crankshaft (36) extending vertically, a flywheel 56 provided on the crankshaft (36) below the engine body, an oil pump (58), and a flywheel chamber (59) defined by a pump body (65) of the oil pump (58) united to coupling walls 61, 62 of the engine body to accommodate the flywheel 56; and a mount case (4) having a support wall 64 for uniting the engine body. The engine body is united with its coupling walls (61, 62) to the support wall (64) via an outer circumferential wall (63) of the pump body (65) such that the coupling walls (61, 62), outer circumferential wall (63) and support wall (64) overlap in the direction of a rotation axis of the crankshaft (36). Such outboard engine permits a connecting portion between the engine body and the mount case, which are united together via the oil pump body, to be decreased in size and weight.

摘要： A box-shaped intake silencer for an engine is obtained by joining together an upper half and a lower half. The intake silencer includes a connecting duct for supplying air to the engine and an intake duct for bringing in outside air. The intake silencer brings in a blow-by gas generated by the engine and returns fresh air purified by a filter to the engine. The filter is inserted into a retaining part made up of the upper and lower halve and held at the retaining pat by joining the upper and lower halves together.

摘要： A vertical internal combustion engine E is incorporated into an outboard motor or the like. The vertical internal combustion engine E includes a crankshaft 18 enclosed in a crank chamber 20, and a belt-drive transmission mechanism 50 including a rubber belt 53 for transmitting power of the crankshaft 18 to a camshaft 24, and held in a belt chamber 63. The belt chamber 63 is isolated from the crank chamber 20 by a lower case 61 of a transmission case 60 holding the belt-drive transmission mechanism 50 therein such that the flow of an oil-containing gas from the crank chamber 20 deviates from a direction toward the belt 53. The belt 53 is lubricated with oil injected concentratedly into the belt chamber 63 through jet nozzles 80 disposed in the belt chamber 63. Thus the excessive exposure of the belt 53 to the oil-containing gas from the crank chamber can be avoided, the life of the belt can be extended and the belt is lubricated properly.
