摘要： The present invention relates to an exhaust system (24) for a combustion engine (30) of a marine vessel (1). The exhaust system (24) includes a flow redirection arrangement (48, 50, 56) in the exhaust gas flow path for restricting a flow of liquid flowing in the reverse flow direction towards the exhaust system inlet. A chamber is disposed in the exhaust gas flow path. The flow redirection arrangement includes a baffle plate configured to direct a first stream of the liquid to a first side of the baffle plate and to direct a second stream of the liquid to a second side of the baffle plate to split the flow of liquid into the first and second streams. The exhaust system also includes a recessed region, defined by a first surface of the chamber, into which the baffle plate is configured to guide the first stream. The recessed region is configured to direct the first stream back towards the second stream to collide therewith. The invention also relates to motor assemblies and marine vessels having such exhaust systems.

摘要： A boat drive (1) comprising an internal combustion engine (3) arranged in the interior of a ship body (2), a drive unit (4) which is arranged outside the ship body and which has a propeller shaft (5), and an exhaust system (6) with an exhaust-gas duct (7) and an exhaust-gas outlet (8). Here, the exhaust-gas duct connects the internal combustion engine to the exhaust-gas outlet in order to discharge exhaust gases of the internal combustion engine and cooling water (9) that has been introduced into the exhaust-gas duct. The exhaust-gas outlet is arranged on the propeller shaft. A first exhaust-gas release opening (10) is arranged in the exhaust-gas duct between the internal combustion engine and the exhaust-gas outlet, wherein, during operation, a first fraction (15) of the exhaust gases and of the cooling water is discharged through the first exhaust-gas release opening, and a second fraction (16) of the exhaust gases and of the cooling water is discharged through the exhaust-gas outlet. Means (11) are provided for setting the first fraction that can be discharged through the first exhaust-gas release opening.

摘要： A marine wet exhaust system (10) which injects water into the exhaust flow for cooling and attenuating noise includes a particulate capture and containment system (14) for removing particulates and fluid contaminants from the exhaust gas and the waste cooling water of the discharge. With a first embodiment, this is accomplished by separating the waste cooling water and entrained particulates from the exhaust gas in a muffler/separator (12); accumulating the waste cooling water and entrained particulates in a reservoir (52); and separating the entrained particulates from the waste cooling water in a filter (50). The system further includes a reservoir discharge pump assembly (54), a reservoir drain line (86) and a bleed line (74) to maintain water levels in the reservoir and the filter. With a second embodiment, a condensate trap (56) separates particulates and condensates from the de-watered exhaust gas and returns them to the reservoir (52).

摘要： An engine (6, 206) includes a cylinder block (19) including a plurality of cylinders (18) disposed along a V-shaped line (V1), a pair of exhaust manifolds (25) disposed inside the V-shaped line, and an exhaust pipe (26, 226) disposed inside the V-shaped line (V1). Each of the pair of exhaust manifolds (25) includes a first passage (49) that includes a plurality of inflow ports (49a) into which exhaust gases from the cylinders (18) flow, a collecting portion (49c) at which exhaust gases are collected, and an exhaust port (49b) from which exhaust gases are discharged. The exhaust pipe (26, 226) includes a connection passage (50, 250) that includes a pair of intermediate inflow ports (50a) that are connected to the exhaust ports (49b), at least one intermediate exhaust port (50b) from which exhaust gases are discharged. The connection passage (50, 250) is arranged to connect the pair of intermediate inflow ports (50a) and the at least one intermediate exhaust port (50b).
