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).
