摘要： A device (a silencer) for silencing a flow, comprises at least one acoustic chamber through-flowed by gas, e.g., exhaust gas, at least one inlet pipe and at least one pipe or passage interconnecting two chambers or a chamber and an exterior environment or chamber and is designed with such cross-sectional area transitions between passages and the chambers that the sound attenuation achieved by the device is high while the pressure drop across the silencer is low and that high attenuation at low characteristic frequencies of flow systems comprising the device are obtained. One or more diffusers and/or monolithic bodies or catalysts may be comprised in the device. The passages may be curved or helical so as to allow for a low natural frequency. Embodiments with resonance chambers attenuating at selected frequencies are disclosed. A method for operating a vehicle comprising a combustion engine and a silencing system is disclosed.

One or more diffusers (10a, 12a, 13a) for diffusing at least part of the gas flow, e.g., at the inlet to the chambers may be comprised in the device. One or more monolithic bodies or catalysers may be comprised in the device. Devices with curved or helical passages (Fig. 5) allowing a low natural frequency and embodiments having resonance chambers (Fig. 10a, b) attenuating at selected frequencies are disclosed. The device may be used for vehicles, including ships or boats and for stationary installations, such as power plants or stationary engines. A method for designing and/or dimensioning the device for a given desired sound attenuation over a given frequency spectrum at given spatial restrictions is disclosed.

摘要： A silencer that comprises a casing, one or more pipes or passages leading a flow of gas to said casing and means for leading gas from said casing. The silencer further comprises at least one internal chamber, one or more flow inlets to said chamber and one or more flow outlets from said chamber, and one or more flow distributing means connected to said flow inlet(s) and/or to said flow outlet(s). The flow distributing means comprises one or more walls or profiles extending on a geometrical surface that defines a boundary between an inner volume of said flow distributing means and said chamber. The silencer further comprises one or more apertures for a flow of gas through said apertures and for leading gas either out of said inner volume into said chamber, or into said inner volume from said chamber. The apertures have a smallest cross-sectional transverse dimension s and a length L, said dimension s being at the maximum 0.2 times the smallest cross-sectional dimension D of the inlet or outlet. The length L is at least the same as said dimension s.

摘要： The invention relates to a silencer being designed with sound absorptive material (13, 23) and a conduit section (1, 2) with one or more conduits (1) for leading gas flow into the silencer and with one or more outlets (2) for leading gas form the silencer. The sound absorptive material (13, 23) and the conduit section (1, 2) constitutes a protrusion extending from part of an outer shell (4) such as from an end cap (5, 6) constituting part of the shell for the silencer, or from an internal member, such as a baffle (9, 10) possibly separating at least two through-flowed chamber (12) of the silencer. Not-through-flowed cavities (17, 27) are arranged essentially adjacent to or at least partly surrounding said sound absorptive material (13, 23), thereby constituting one or more resonators acoustically communicating with said at least one through-flowed chamber. The silencer may also be designed so as to act as a spark-arrestor. Also, the invention relates to a combustion engine provided with such silencer.
