摘要： An engine includes an engine body and an air induction system. The engine body includes a cylinder block defining a cylinder bore in which a piston reciprocates. A cylinder head member closes an end of the cylinder bore to define a combustion chamber together with the cylinder bore and the piston. The air induction system is arranged to introduce air into the combustion chamber. The induction system includes a first intake conduit through which the air flows to the combustion chamber. A first plenum chamber unit is disposed upstream of the first intake conduit. A control mechanism is arranged to control an amount of the air flowing through the first intake conduit. The induction system also includes a second intake conduit through which the air flows to the combustion chamber. A second plenum chamber unit is disposed upstream of the second intake conduit. The second intake conduit is coupled with the first intake conduit downstream of the control mechanism.

摘要： A fuel injected induction system for a crankcase compression, two-cycle, V-type internal combustion engine includes a plurality of throttle valves corresponding in number to the number of crankcase chamber of the engine. Each throttle valve communicates with a dedicated intake passage that directly communicates with a respective crankcase chamber. At least one fuel injector is positioned within each intake passage in order to form the air/fuel charge delivered to the crankcase chamber. The corresponding number of throttle valves, fuel injectors and crankcase chambers allows for enhanced control over the air-fuel ratio delivered to each of the cylinders, as well as improved consistence of the air-fuel charge delivered to each of the cylinders of the engine.

摘要： A marine drive has an open loop cooling system for cooling various engine components using water drawn from the body of water in which an associated watercraft is operating. A water inlet of the cooling system has a filter cover which includes a series of apertures through which water can flow. The apertures have a maximum cross-sectional width. After passing through the water inlet, cooling water is pressurized and directed to an engine coolant passage to cool engine components. A pilot water passage branches off of the engine coolant passage and delivers cooling water through peripheral engine components to cool the components. The pilot cooling water is discharged from the marine drive in a pilot water stream that is visible to the operator of the watercraft. No portion of the pilot water passage has a diameter that is less than the maximum dimension of the water inlet filter cover openings.

摘要： An outboard motor mounted to a hull of a watercraft includes a V-type engine having right and left cylinder banks positioned in a cowling and having a crankshaft generally vertically disposed when the watercraft is under a running condition. A surge tank is disposed in the cowling. Right and left side long intake conduits and right and left side short intake conduits both connect the surge tank to intake ports of respective right and left banks of cylinders. The associated long intake conduits and short intake conduits can be selectively established depending on information about operational conditions of the hull and/or the outboard motor. The outboard motor includes right and left shut-off valves interchanging the long intake conduits and the short intake conduits. Right and left actuators individually actuate the right and left shut-off valves in accordance with information about operational conditions. A control means individually controls operations of the respective actuators.

摘要： An intermediate drive mechanism allows an alternator to be mounted beneath an engine flywheel on the side of the engine. This location reduces both the girth and height of the engine, thereby reducing the size of the power head of an outboard motor. The intermediate drive mechanism includes a first intermediate pulley, which lies generally at the same level as a drive pulley attached to the engine output shaft. A second intermediate pulley lies beneath the first intermediate pulley and generally at the same level as a driven pulley of the generator. Belts couple the pulleys of the intermediate drive mechanism to the respective drive and driven pulleys. The intermediate pulleys also can move relative to the corresponding pulleys so as to function as a belt tensioner.
