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 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 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： 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.

摘要： An oil pump for a lubricating system of an outboard motor is disclosed. The motor has a cowling defining an engine compartment, a water propulsion device, and a guide member having an upper surface and a lower surface, the guide member positioned in the cowling and generally dividing the engine compartment into an upper part and a lower part. An engine is positioned in the upper part of the engine compartment within the cowling and has an output shaft arranged to drive the water propulsion device. The lubricating system includes an oil pan positioned below the guide member and an oil passage leading from the pan through the guide member. The oil pump is positioned in the upper part of the engine compartment, but below the engine, and is driven by a lower end of the output shaft of the engine which extends below the engine, the oil pump having an oil inlet in communication with the oil passage through the guide member.
