Embodiment Construction

[0097] The present invention will now be described with reference to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims. The drawings described are only schematic and non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes. The dimensions and relative dimensions do not correspond to actual implementations of the invention.

[0098] The following terms are provided only to aid in the understanding of the present invention.

[0099] The term "porosity" P should be understood as P=100*(1-d), where d=(1m 3 weight of sintered metal fiber medium) / (SF), where SF = per m of the alloy used to provide the metal fibers of the sintered metal fiber medium 3 proportion.

[0100] The term "air permeability" (also referred to as AP) is measured using a device as described in NF95-352 equivalent to ISO 4002. The test method of NF 95-352 (he...

Abstract

The invention relates to diesel soot particulate filter cartridge having a central filter cartridge axis. The filter cartridge has a radial flow. The filter cartridge comprises a porous structure. The porous structure is coiled around the central filter cartridge axis. The porous structure comprises non-sintered metal fibers, said fibers having a roughness being higher than 1.7. The invention further relates to a method of manufacturing a diesel soot particulate filter cartridge. Furthermore the invention relates to a multicartridge diesel soot particulate filter. The flow through the multicartridge diesel soot particulate filter is axial while the flow through the filter cartridges is radial.

Description

technical field [0001] The present invention relates to a radial diesel soot particulate filter cartridge and a method of making the filter cartridge. [0002] The invention also relates to a multi-cartridge filter comprising a plurality of radial filter cartridges and a method of making the multi-cartridge filter. Background technique [0003] A diesel soot particulate filter comprising metal fibers is known, for example, from WO 2007 / 079829. This type of filter is called an axial filter because the flow is axial. However, this type of filter has many disadvantages, such as limited inflow area and high pressure drop. [0004] Also ceramic filters are known in the art for filtering diesel engine exhaust. However, they are characterized by a high thermal mass, resulting in long regeneration times. Furthermore, their mass efficiency is not adjustable. Contents of the invention [0005] It is an object of the present invention to provide a diesel soot particulate filter ...
