Definitions

  • the invention relates to a device on an internal combustion engine for retaining combustion residues, e.g. Soot, with a filter material arranged in a container with an inlet and outlet line.
  • combustion residues e.g. Soot
  • soot filters with a smooth metal fiber fleece and a corrugated steel foil and baffles are known from practice. The effectiveness of these soot filters appears to be satisfactory, but they have a complicated structure and are therefore difficult to manufacture.
  • the invention has for its object to provide a device of the type mentioned, which is easy to manufacture.
  • the filter material is formed in two layers to form a cavity and a plurality of such cavities are arranged contiguously and parallel to each other.
  • An advantageous embodiment of the invention is characterized in that the cavities are arranged in a spiral.
  • the filter structure with the cavities can be produced endlessly and then wound up in a spiral.
  • Another advantageous embodiment of the invention is that the cavities are arranged in a meandering shape.
  • Soot filter devices with almost any cross section can be produced with both the spiral and the meandering arrangement.
  • a further advantageous embodiment of the invention is characterized in that the filter material consists of a filter cloth, preferably a metal cloth.
  • a perforated metal foil is provided as the filter material.
  • Another advantageous embodiment of the invention is characterized in that the filter material is coated.
  • a strip of the filter material is folded along a longitudinal center line to form the cavities, elongated cavities arranged parallel to one another being formed between the two partial strips.
  • the two partial strips lie against one another at least linearly between the cavities.
  • the two partial strips between the cavities are connected by welding or the like.
  • a further advantageous embodiment of the invention is characterized in that a piece of pipe is inserted into the open end of each cavity.
  • a further increase in strength results in an embodiment according to the invention in that the pipe section is connected to the filter material by welding or the like.
  • the pipe pieces are inserted into bores in a connection plate. It can be particularly advantageous if, according to a further advantageous embodiment of the invention, the free ends of the pipe pieces located in the plate are crimped at the edge of the respective bore.
  • a further advantageous embodiment of the invention is characterized in that a flap formed during folding is formed on the respective intermediate piece lying between the cavities and can be used to fix the filter material.
  • FIG. 5 shows a section of a filter mat with a tube piece inserted into a cavity.
  • 1 in FIG. 1 denotes a filter mat, which is folded together from a strip of metal mesh 2 around a longitudinal center line 3.
  • semicircular grooves are formed in cross-section in a manner not shown, and then, when folded, cavities 4 are formed by these grooves, which are closed on one side and open on the other side.
  • the two layers can be connected to one another by a weld seam or by individual weld points 6.
  • they are somewhat shorter in the region of the longitudinal center line 3 than the intermediate pieces 5, on the lower end of which tabs 7 are thereby formed.
  • the metal mesh 2 is coated over the entire surface in an invisible manner.
  • a filter mat 1 is wound spirally to form a filter device 21 which is circular in cross section and which is inserted into a filter housing 22 with a likewise circular cross section.
  • the filter mat 1 can also be arranged in other geometric shapes.
  • FIG. 3 shows, for example, a likewise spiral arrangement of a filter device 31, which has an oval cross section.
  • any cross-sectional shapes are possible.
  • soot and mineral residues When operating a diesel engine, soot and mineral residues cling to the filter fabric arranged in the exhaust line.
  • the soot can be largely burned on the filter mat, for example by adding additives; however, the mineral residues accumulate.
  • the mineral residues and any soot residues can be rinsed out of the filter device by a rinsing process.

Abstract

L'invention concerne un équipement d'un moteur à combustion interne destiné à retenir des résidus de combustion, comme la suie. Cet équipement comprend une matière filtrante placée dans contenant (22) doté d'une conduite d'entrée et d'une conduite de sortie. Cette matière filtrante est constituée de deux couches et forme une cavité (4). Plusieurs cavités (4) de ce type communiquent et sont placées parallèlement les unes aux autres.
