摘要： An outboard motor which is capable of suppressing discoloration around an exhaust hollow is provided. An outboard motor 5 includes an engine 9, a drive shaft 10, a propeller shaft 11, a housing 14, an exhaust passage P1, a water intake passage Q, and a valve structure 40. The exhaust passage P1 guides an exhaust gas from the engine 9 toward the discharge chamber R inside the housing 14. The water intake passage Q guides water, which enters an inside of the housing 14, to the discharge chamber R, when a forward propulsive force is generated. The valve structure 40 regulates passage of the exhaust gas at the first hollow portion 131c1 by water pressure, when a forward propulsive force is generated. The valve structure 40 permits the passage of exhaust gas at the first hollow portion 131c1 by exhaust pressure, when a backward propulsive force is generated.

摘要： A method for controlling the saturation level of gas in a liquid discharge, for example effluent gases of a vehicle underwater, includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and a pressure measurement of a source feedstock in a feedstock tank, correlating said measurements to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement and generating a valve operating control law for how the feedstock valve should function in a cycle. In that way, an effluent discharge solution having a known gas solubility saturation is generated avoiding bubble discharge.

摘要： A marine craft (10) having a propeller tunnel (20) in which the sidewalls (31) of the tunnel are essentially parallel and vertical and mate with a descending upper surface of the tunnel which optionally can be divided into a transom plate portion (21), engine plate portion (22), and bottom plate portion (24). The bottom plate portion mates with the bottom of the boat hull in a sharp line intersection. A surfacing propeller (25) and associated drive shaft (26) is mounted in the tunnel with a rudder (18) positioned aft of the surfacing propeller. Baffles (32) are provided on the lateral sides of the tunnel and terminate in a forward portion (34) aft of the bottom plate portion of the tunnel. Optionally the exhaust (45) can be vented onto the bottom plate portion of the tunnel to augment the flow of air.

摘要： A method for controlling the exit of exhaust gases from an engine which is used to power an underwater propeller drive arranged at the hull bottom of a boat is provided. According to the method exhaust gases are allowed to flow from the engine through an exhaust channel and exit through a first underwater exhaust outlet in the underwater propeller drive. According to the method, if the engine is running and the transmission of the propeller drive is in neutral position, a second underwater exhaust outlet is opened for letting exhaust gases in the exhaust channel exit in a position closer to the hull bottom of the boat than the first underwater exhaust outlet.
