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

Abstract: A device for silencing a flow includes 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 are obtained. The device may contain at least one of diffusers, monolithic bodies and catalysts. 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 including a combustion engine and a silencing system is disclosed.

Abstract: A silencer, for silencing and purification of exhaust gases, comprises an air-tight casing (1) connected to an exhaust inlet pipe (2) and to an exhaust outlet pipe (3) and contains at least two acoustic compartments (4i, 4ii) and one or more monolithic bodies (5) such as catalysers or particle filters through which exhaust gases flow in a flow direction in longitudinal channels or porosities, and one or more pipes or channels (6, 7), at least one pipe or channel penetrating one or more of the monolithic bodies (5) and guiding exhaust gases in a flow direction which is opposite to the flow direction in the channels or porosities of the monolithic body (5), and at least one of the pipes or channels (6, 7) connecting the at least two acoustic compartments (4i, 4ii). The general flow direction is preferably reversed substantially immediately upstream of a penetrated monolithic body (5) and substantially immediately downstream of either the same monolithic body (5) or of another penetrated monolithic body.

The silencer with built-in catalyser comprises a casing (1) connected to an inlet pipe (2) and to an outlet pipe (3), a sound attenuation compartment (4), a downstream catalytic body (5), a flow-area widening diffuser element (6) extending from the inlet pipe and contained within the compartment, and a cross-plate (7) which is positioned between the diffuser element and the catalytic body and from which the flow is distributed evenly across the inlet to the catalytic body. At least two openings (8) are provided between the diffuser element and the catalytic body, at least one such opening (9) providing a communication to the sound attenuation compartment and at least two such openings (10) being pervaded by gas flows.

Abstract: An apparatus for silencing and catalytic treatment of gases has an air-tight casing connected to an exhaust inlet pipe and to an exhaust outlet pipe, acoustic compartments, monolithic bodies, and a diffuser element. The diffuser element is connected to the inlet pipe, or further downstream within the casing. The diffuser element distributes the gases evenly across the inlet face of the monolithic bodies. The diffuser element is a guide baffle or plate and a juxtaposed stagnation baffle or plate, which causes both flow stagnation in front of the stagnation plate and the gases to flow radially within the diffuser element. The diffuser element has apertures which are pervaded by partial flows of the gas and are adapted to provide additional recovery in the gas flow passing through the diffuser element. The geometry defining the fluid flow field within the diffuser is designed to prevent flow separation from the contour walls of the diffuser.
