摘要： A fuel injection system for an internal combustion engine of the type utilized to power an outboard motor of a watercraft is disclosed. The engine is oriented with its crankshaft vertically extending, such that the engine has a top and a bottom, a first end and a second end, and a side between the ends. An air delivery passage extends generally from the first end along said side to an intake passage leading through the engine to a combustion chamber therein. A fuel injector is positioned along the side of the engine and arranged to deliver fuel into air flowing through the passage. In one arrangement, the fuel injector is connected to an intake manifold defining at least a part of the air delivery passage and is adapted to deliver fuel opposite the flow of air through the passage at the point of delivery. In a second embodiment, the fuel injector is positioned between the air delivery passage and the side of the engine. In this embodiment, the fuel injector is preferably arranged to deliver fuel perpendicular to the flow of air through the passage.

摘要： A crankcase arrangement for an engine includes an improved construction that allows lubricant to more freely flow through the crankcase and to quickly return to a lubricant reservoir even though the engine has a compact construction. A cylinder body of an exemplifying engine includes at least an upper bearing portion, intermediate bearing portion and lower bearing portion. A crankcase member, which defines a crankcase cavity with the cylinder body, includes an upper bearing section and a lower bearing section. An upper main bearing journal of a crankshaft is rotatably journaled between the upper bearing portion and the upper bearing section and a lower main bearing journal of the crankshaft is rotatably journaled between the lower bearing portion and the lower bearing section. A bearing cap is arranged to rotatably journal the crankshaft with the intermediate bearing portion. In a preferred form, the bearing cap includes a plurality of cap sections that are joined together. Each cap section cooperates with a corresponding intermediate bearing portion of the cylinder body. Intermediate main bearings, which are formed by the cooperating cap sections and intermediate bearing portions, journal the crankshaft at a plurality of locations between the upper and lower main bearing journals of the crankshaft.

摘要： An outboard motor having a multi-cylinder four-cycle, internal combustion engine as a power plant. An improved crankcase ventilating system is provided wherein the crankcase ventilating gases follow a circuitous path through the crankcase chamber, camshaft chambers and then to the intake system through an extended conduit passing over the exhaust manifold so as to reduce the emissions of hydrocarbons. The intake system is designed to preclude uneven distribution of the ventilating gases. The intake system also is comprised of a plenum device, a plurality of runners and throttle bodies and an intake manifold that are attached as a unit to the rest of the engine body. Portions of this unit are formed from a synthetic resin.
