摘要： A lubrication system for a direct injected V-type two-cycle engine is disclosed having a lubricant pump adapted to discharge lubricant into each crankcase chamber of the engine through ports positioned adjacent the downstream side of reed valves of the air intake system. Ports supplying lubricant to cylinders in the right cylinder bank of the engine extend through a left wall of the corresponding crankcase chamber. Ports supplying lubricant to cylinders in the left cylinder bank of the engine extend through a right wall of the corresponding crankcase chamber. During engine assembly, the lubricant pump is manually driven before it is mechanically installed so as to fill the attached supply hoses with lubricant. The pump delivers lubricant to each crankcase chamber at a rate high enough to avoid lubricant carbonization at engine idle and low enough to avoid lubricant resistance to crankshaft rotation, which may make the engine difficult to start.

摘要： A lubrication system for a direct injected two-cycle engine is disclosed having a lubricant pump adapted to discharge lubricant into each crankcase chamber of the engine through a port positioned immediately adjacent the downstream side of reed valves of the air intake system. The lubricant is injected in a direction generally coincident with the rotational direction of the crankshaft. Drain ports are positioned in the lowermost scavenge passage of each cylinder and communicate lubricant from the scavenge passage to a return port formed through the wall of a crankcase chamber.

摘要： An outboard motor comprises a cowling, having a top cowling and a bottom cowling, that cooperate to define an engine compartment. An intake air duct draws outside air into the engine compartment. A water collecting part is arranged in the bottom cowling for accumulating water that may enter the cowling through the air duct. A water passage may also be provided for guiding water from the intake air duct to the water collecting part. The water passage may have air openings for allowing air to enter the engine compartment independent of the water. A floor of the engine compartment may be adapted to contain water splashing and direct water to a water collecting part.

摘要： An engine lubrication control includes an improved construction. The engine has a lubrication device that delivers lubricant to a crankcase of the engine in following rotational speed of a crankshaft rotating in the crankcase. The lubricant device includes an adjustment mechanism for adjusting a volume of the lubricant. The adjustment mechanism has at least two positions and increases the lubricant volume delivered when the mechanism is located at one of the positions relative to when the mechanism is located at the other position.

摘要： A lubricating system is disclosed for an engine arranged such that the crankshaft is vertically oriented. The crankshaft rotates within a crankcase chamber defined by the cylinder block and a crankcase cover connected thereto. First crankshaft support members which support half-bearings extend from the cylinder block. Mating half-bearings are supported by second crankshaft support members positioned opposite the first crankshaft support members. A baffle plate is positioned in the crankcase chamber between the crankcase cover and the crankshaft. At least one oil flow passage is defined through the crankcase chamber from a top end to a bottom end of the chamber. In one embodiment, oil is supplied through a main passage in the crankcase cover and a branch passage through each second crankshaft support members for lubricating the bearings.

摘要： A number of the embodiments of exhaust systems and oil tank arrangements for four-cycle internal combustion engine powered outboard motors. In all of the embodiments, idle exhaust gases are discharged to the atmosphere through a path that extends above the oil tank. A cooling jacket is formed around an exhaust pipe that depends through a cavity in the oil tank and coolant from this cooling jacket is discharged to the exterior surface of the exhaust pipe so as to cool it. Cooling water from the engine and from the exhaust pipe cooling jacket is isolated from the idle exhaust gas discharge so as to ensure that this cooling water cannot enter the engine through the idle exhaust gas discharge path.

摘要： A lubrication system of an outboard motor delivers lubricant to an internal combustion engine. The internal combustion engine is supported by an upper end of a case. The lubrication system has an oil pan configured to hold lubricant oil. An oil conduit has a lower end opening to the oil pan. An upper end of the oil conduit extends towards the internal combustion engine. An oil pump delivers the lubricant oil towards the internal combustion engine through the oil conduit. The oil pump is located in the vicinity of a front part of the oil pan as viewed from the side of the outboard motor. An inside bottom surface of the oil pan defines a lower bottom portion and an upper bottom portion. The lower bottom portion is located under the lower end of the oil conduit. The upper bottom portion of the oil pan is positioned rearward of the lower bottom portion.

摘要： An outboard motor has a cowling for enclosing an engine. Air inlet openings are formed in the cowling. An air intake chamber connects the air inlet openings and an air intake duct. Air that flows through the air inlet openings passes through the air intake chamber to the air intake duct. The air is then introduced into the engine. A front wall of the air intake chamber has a center portion positioned rearwardly of outer portions of the front wall. The air intake duct is positioned rearwardly of the front wall of the air intake chamber. The air inlet openings are positioned on both sides of the air intake duct. A rear wall is positioned rearwardly of the air intake duct. Each of the air inlet openings extends from the rear wall to one of the outer ends of the front wall of the air intake chamber.

摘要： A silencing arrangement for the induction system of an internal combustion engine particularly as applied to an outboard motor. The engine silencing system includes at least one intake silencing valve that controls the emanation of sounds from the interior of the plenum chamber of the silencing device to the atmosphere. This valve position does not restrict airflow under the controlled positions. The valve can be positioned either in response to engine load as determined by factors such as throttle position or by engine speed.
