20090078498 | SEAMLESS IN-LINE AIRBOAT MUFFLER - A muffler comprising a generally cylindrical in-line muffler having a seamless outer body for use in silencing airboat engines is disclosed. An inner perforated stainless steel inner tube is surrounded by a stainless steel mesh liner and a stainless steel outer body having opposing ends swaged to a reduced diameter. The use of all stainless steel components provides a muffler that is highly resistant to corrosion. In addition, the muffler is ideally suited for use in marine environments since it is capable of discharging ingested water as the stainless steel perforated inner tube and mesh liner will not become water logged. A method for fabricating mufflers in accordance with the present invention if further disclosed. | 03-26-2009 |
20100000821 | MARINE MUFFLER WITH ANGULARLY DISPOSED INTERNAL BAFFLE - 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. | 01-07-2010 |
20100041287 | GASKETED CONNECTION OF MARINE ENGINE EXHAUST OUTLET TO EXHAUST CONDUIT - A connecting flange comprises a generally open ended cylindrical body having an inlet adapted for receiving a gasket for providing a sealing connection with a turbocharger housing, and an outlet for connection to marine exhaust conduit. The connector inlet terminates in an end having a radially flared angularly disposed end wall adapted for mating abutting engagement with a correspondingly angled turbocharger housing end wall. The connector inlet end further includes circumferential axially recessed groove that receives spiral wound gasket in a configuration wherein the gasket forms redundant seals at a plurality of locations. The connector inlet structure cooperates with the turbo charger outlet structure to completely enclose the gasket thereby protecting the gasket from hot corrosive exhaust gases. A V-Band clamp is disposed in covering relation with the connector end wall and abutting turbocharger housing component to secure the connector to the turbocharger. | 02-18-2010 |
20100041288 | SUBMERGED EXHAUST DISCHARGE FOR MARINE VESSEL - 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. | 02-18-2010 |

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.
