摘要: An exhaust system for an internal combustion engine of an outboard motor is provided. The exhaust system provides dual exhaust passages, simplifying the engine's construction and reducing manufacturing costs, while optimizing engine performance. The exhaust system includes exhaust ports having equal lengths that avoid differential pressure losses across cylinders. The arrangement of the exhaust passages enables a cowling to have a tapered aerodynamic design.

摘要: A fuel supply for an internal combustion engine includes an improved construction for inhibiting vapor from appearing in the fuel supplied to the engine's combustion chamber(s). A fuel injector, as one of fuel supply devices, is provided for supplying fuel to the combustion chamber of the engine. There are a first and second fuel reservoirs. The first fuel reservoir stores fuel and delivers it to the second fuel reservoir through a first fuel supply conduit, while the second fuel reservoir temporarily store the fuel and delivers it to the fuel injector through a second fuel supply conduit. The excess fuel is returned to the second fuel reservoir from the fuel injector through a fuel return conduit. The fuel supply includes a fuel cooling device for cooling the fuel passing through at least one of the conduits. The construction of the fuel supply and the fuel cooling device permits them to be located with the tight confines between the engine and a protective enclosure (e.g., a cowling of an outboard motor).

摘要: An outboard motor incorporates a driveshaft and a propulsion shaft driven by the driveshaft. The driveshaft carries a pinion. The propulsion shaft carries forward and reverse gears. The pinion always meshes with the forward and reverse gear and drives the forward and reverse gears in opposite directions relative to each other. A hydraulic forward clutch mechanism couples the forward gear with the propulsion shaft. A hydraulic reverse clutch mechanism couples the reverse gear with the propulsion shaft. A shift actuator selectively operates the forward clutch mechanism or the reverse clutch mechanism to provide forward, reverse and/or neutral running conditions for the outboard motor.

摘要: A cowling assembly for an outboard motor includes an improved construction that can supply relatively cool air containing little if no water to the induction device and that can also supply air to cool engine components without reducing the charging efficiency. The outboard motor has an engine that includes an air induction device and is enclosed by the cowling. The induction device has an air inlet opening. The cowling assembly defines a closed cavity in which the engine is contained and has an air intake duct that introduces air into the cavity. The intake duct adjoins the inlet opening and has an opening opened to the cavity and positioned lower than a lower end of the inlet opening. In one form, the cowling assembly has at least one front air intake opening formed on a side surface of its front portion. A rear air intake opening is also formed on a rear surface of its rear end portion. The cowling front air opening primarily supplies air to the induction system, while the cowling rear air opening primarily supplies a cooling air flow across the engine.

摘要: A direct fuel injector is positioned to provide better fuel atomization within the combustion chamber. The direct fuel injector is disposed between an intake manifold and a cylinder head assembly thereby eliminating the need for additional fuel delivery conduits, thus decreasing the size of the engine and lowering the production costs of the outboard motor. The direct fuel injector position permits immediate air/fuel mixture adjustments allowing improved acceleration enrichment and lean stratified charge operation. The direct fuel injector position and routing of induction system components allows for compact placement of auxiliary components. The integrated direct fuel injector position enables the operator to enjoy compact engine design, improved engine performance and increased fuel efficiency.

摘要: A blow-by gas ventilation system for a crankcase of an engine includes an improved construction for distributing blow-by gases more evenly between multiple cylinders. The engine has an air intake device that includes a plurality of air delivery conduits for the cylinders and a plenum chamber housing disposed upstream of the air delivery conduits. The ventilation system comprises a blow-by gas conduit that couples the crankcase with the plenum chamber housing. The plenum chamber housing includes an opening to which the blow-by gas conduit is connected. A baffle is disposed in front of the opening within the plenum chamber housing so as to divide the blow-by gases equally for the respective cylinders.
