摘要： An oil separator comprises an oil chamber having a first space on an upper side and a second space on a lower side which communicate with each other. An air-fuel mixture transport pipe is connected to a peripheral portion of the oil chamber so as to communicate with the second space. An oil discharge pipe is connected to a lower end portion of the oil chamber. A blow-by gas discharge pipe is connected to an upper end portion of the oil chamber. The second space communicates with the first space so as to inhibit the oil from flowing from the second space into the first space. The first space communicates with the blow-by gas discharge pipe so as to inhibit the oil from flowing from the first space into the blow-by gas discharge pipe. The flow direction at one end portion of the air-fuel mixture transport pipe substantially corresponds with the circumferential direction of the oil chamber.

摘要： A first exhaust chamber and a second exhaust chamber are disposed within a body of a watercraft. The first exhaust chamber communicates with an exhaust port of an engine through a first exhaust pipe. A first space of the first exhaust chamber communicates with the second exhaust chamber through a first inverted-U shaped pipe. The second exhaust chamber communicates with another space of the first exhaust chamber through a second inverted-U shaped pipe. The first and second inverted-U shaped pipes are each positioned in the flow path of the exhaust gas and bent to be substantially inverted-U shaped. The other space of the first exhaust chamber communicates with an outside of the body through a second exhaust pipe. An uppermost portion of the first inverted-U shaped pipe and an uppermost portion of the second inverted-U shaped pipe are located higher than a waterline of the watercraft.
