    摘要: A water separator for use in a marine exhaust system comprises a horizontally disposed, generally cylindrical housing including a wet exhaust inlet, a dry exhaust outlet, and a water outlet. Wet exhaust entering the wet exhaust inlet is constrained against the inner housing wall by a variable geometry vane or baffle which causes the wet exhaust to accelerate such that centrifugal force causes the entrained water to separate from the exhaust gas. Separated water encounters a longitudinally disposed barrier and flows to the water outlet for discharge from the vessel. A tubular dry exhaust pipe is longitudinally disposed within the housing and includes an inlet disposed in proximity to a first end thereof, and an outlet projecting from a second end thereof.

    摘要: A marine muffler capable of handling both marine engine exhaust gas and marine engine cooling water includes a double wall baffle partitioning the muffler interior so as to function as a cooling water conduit. The cooling water conduit includes an inlet disposed external to the main muffler housing and an outlet configured and disposed so as to discharge the engine cooling water into the exhaust duct connected to the muffler outlet. The muffler is thus able to convey the engine cooling water through the muffler housing within a dedicated conduit while maintaining the cooling water separate from the exhaust gas. A muffler that is adapted to handle both the exhaust and cooling water flowing from a marine engine allows for the elimination of engine cooling water piping.

    摘要: A water jacketed exhaust component includes an exhaust pipe having a radially inwardly tapered tail end, a water jacket disposed in surrounding relation with the exhaust pipe, and a generally V-shaped spray ring. The spray ring includes a first and second set of apertures that create diverging streams of cooling water. A first set of apertures creates an annularly disposed series of streams that are directed downstream and radially inward. These streams are generally directed toward the outer surface of the exhaust pipe structure which extends downstream of the spray ring. A second set of apertures creates an annularly disposed series of streams that are directed downstream and radially outward. These streams are generally directed toward the inner surface of the water jacket structure extending downstream of the spray ring. By providing a water jacketed exhaust component with a spray ring that creates diverging streams of cooling water, the present invention provides a water jacketed marine exhaust component that provides improved exhaust gas cooling over a wider range of engine operating conditions. An alternate embodiment includes a V-shaped spray ring configured to create converging streams of cooling water.

    摘要: A water drop muffler for use in a marine exhaust system to silence exhaust noise while separating entrained water from exhaust gas using hydro-dynamic centrifugal separation principles enhanced by turbulent flow. A muffler housing defines an internal volume bounded by a generally vertically disposed cylindrical inner surface formed about a longitudinal axis. An exhaust inlet receives a mixture of exhaust gas and entrained cooling water. A flow channel transitions the flow for discharge through an opening thereby creating vortex flow within the housing to maximize the generation of centrifugal forces. Water is drawn toward the cylindrical inner surface and allowed drain from the housing.

    摘要: A marine muffler comprises an elongate cylindrical housing having an inlet and an outlet and defining an internal volume partitioned, by an angularly disposed internal baffle, into a lower chamber in communication with the inlet and an upper chamber in communication with the outlet. A vertically disposed duct is insertably secured to the baffle to allow exhaust gas and exhaust cooling water to flow from the lower inlet chamber to upper outlet chamber. The exhaust duct may preferably be further adapted with internal structure forming a plurality of individual flow conduits or passages. The duct is preferably positioned such that a plurality of flow passage inlets are positioned in proximity to the lower cylindrical housing wall, with flow passage outlets positioned in proximity to the upper housing wall. The lower duct wall may further be adapted with sidewall apertures for improving exhaust flow dynamics therethrough.

    摘要: A marine exhaust system adapted for discharging marine exhaust below the water line through at least one streamlined conformal discharge fitting attached to the vessel hull. Each discharge fitting comprises a low profile body attached to the vessel hull in relation with an exhaust discharge conduit terminating in a thru-hull opening so as to discharge marine exhaust into the discharge fitting body. The discharge fitting preferably includes a forward end and an aft end connecting a main discharge fitting body disposed in spaced relation with the underside of the vessel hull. The discharge fitting body defines an exhaust outlet disposed on outboard side thereof so as to allow exhaust gas to exit in an outward and aft flow such that corrosive exhaust gas does not flow over the vessel propellers. Forward and aft baffles are disposed within the discharge fitting body to direct and re-direct exhaust gas flow. By maintaining a streamlined and low-profile/conformal shape, reduction in overall hull hydrodynamics due to increased drag is minimized.

    摘要: A marine muffler adapted with an internally tunable sound suppression structure is adaptable to different configurations thereby allowing for structural adjustments to optimize sound suppression and minimize backpressure for particular engine and exhaust conditions. A muffler housing defines an interior volume and includes an exhaust inlet and outlet. The outlet has a reduced diameter as compared with the inlet such that the exhaust gas accelerates through the muffler. An inclined baffle partitions the interior volume into a lower chamber in communication with the exhaust inlet and an upper chamber in communication with the exhaust outlet. Exhaust ducts attached to each side wall penetrate the baffle thereby placing the upper and lower chambers in fluid communication. A corrugated partition divides each exhaust duct into a plurality of non-circular conduits. The muffler may be tuned by selectively capping one or more conduit outlets.
