摘要： An apparatus and method for silencing marine engines. In one embodiment, a separation chamber (100) receives a fluid mixture (22) of exhaust gas (16) and liquid coolant (10) and a dynamic separation member (e.g., 106 or 116) separates the exhaust gas (16) from the liquid coolant (10). In one aspect of the invention, a horizontal axial-flow silencer includes a separation plate, having at least one dynamic separator, horizontally positioned in the separation chamber (100). A dam (130) maintains the free surface of the fluid mixture (22) at or slightly above the separation plate at an engine speed within nominal operating range, and provides for the continuing passage of exhaust gas (16) through the liquid coolant (10). The separation plate employs inertial effects introduced by a series of vanes (107) that deflect the gas-coolant mixture upstream to separate the coolant with a greater inertia from the exhaust gas (16) with a lesser inertia. Alternatively, the separation plate may consist of a mesh pad (116) that employs frictional effects to achieve a similar result. The separate exhaust gas (110) is passed through a resonator tube or tubes (150) to further attenuate the acoustic energy of the gas.

摘要： A silencer (143) is disclosed that reduces the acoustic energy of a fluid mixture (111) of a liquid coolant (109) and of exhaust gas (107) from an engine. The engine may be a marine engine. The silencer (143) according to this aspect includes a receiving chamber (171) that receives the fluid mixture (111) and exhaust gas (107), at least one lifting conduit (175); and a separation chamber (173). The lifting conduit (175) has a receiving portion (177) with a first opening (179) and an expelling portion (181) with a second opening (183). The receiving portion (177) is fluidly coupled with the receiving chamber (171) so that the fluid mixture (111) enters the first opening (179) from the receiving chamber (171) and is lifted through the lifting conduit (175) to the expelling portion (181). This lifting may be accomplished, at least in part, by dynamic effects. The separation chamber (173) is fluidly coupled with the second opening (183) of the lifting conduit (175), and has at least one interior surface (185). The expelling portion (181) of the lifting conduit (175) is disposed so that fluid mixture (111) expelled from the second opening (183) is directed toward the at least one interior surface (185) of the separation chamber (173). The at least one interior surface (185) may dynamically separate, for example by linear momentum effect or centrifugal effect, at least a portion of the exhaust gas (107) from the fluid mixture (111).
