Definitions

  • the present invention relates to a method for producing an exhaust gas treatment device, which contains in a tubular housing at least one exhaust gas treatment insert, in particular for an exhaust system of an internal combustion engine.
  • the invention also relates to an exhaust gas treatment device, in particular for an exhaust system of an internal combustion engine, which contains at least one exhaust gas treatment insert in a tubular housing.
  • Exhaust gas treatment devices such as catalysts and particulate filters, have at least one insert which is arranged in a tubular housing.
  • inserts made of ceramic materials are known.
  • metallic inserts are known. It is customary to arrange the respective use with the help of a use enveloping the bearing mat in the respective housing.
  • This storage mat has several functions. On the one hand, it dampens lateral accelerations to which the exhaust gas treatment insert may be exposed during operation. On the other hand, the bearing mat can form a thermal insulation to the thermal load of the Reduce housing. Furthermore, a positional fixation of the insert in the housing is regularly achieved with the bearing mat. For this purpose, the bearing mat must be pressed radially between the insert and the housing.
  • the radial compression of the bearing mat is relatively problematic, since it can cause damage to the ceramic inserts when excessive forces occur.
  • the inserts in particular ceramic monoliths, can have comparatively large dimensional tolerances, as a result of which local stress peaks can occur during the radial deformation of the housing.
  • a gap formed radially between the respective insert and the housing and filled by the bearing mat in the circumferential direction can thus have an uneven, radially measured gap dimension.
  • the gap dimension can locally become so great that the bearing mat is not sufficiently compressed there, which during operation can lead to the bearing mat being detached at this inadequately compressed point, as a result of which a bypass that forms the insert is formed in the housing.
  • a method for producing catalysts is known in which a breaking characteristic of the ceramic monolith is first determined, which depends on the particular combination of ceramic material and bearing mat material.
  • This breakage characteristic includes in particular the dependence of the forces occurring during pressing of the bearing mat on the speed with which the pressing is carried out.
  • the pressing of the bearing mat is now carried out so that damage to the monolith is avoided.
  • the present invention is concerned with the problem of providing an improved embodiment for a manufacturing method of the type mentioned at the outset or for an exhaust gas treatment insert of the type mentioned above, which is characterized in particular by reducing the risk of damage to the insert during manufacture and / or that a comparatively uniform gap progression in the circumferential direction is achieved.
  • the invention is based on the general idea of measuring the circumferential geometry at least in an axial section during the respective use prior to introduction into the housing and to take into account the measured circumferential geometry during the subsequent deformation of the housing. This can take into account the deformation of the housing in particular tolerance-related form deviations of the respective use. As a result, on the one hand voltage peaks can be avoided. On the other hand, the radial compression of the bearing mat can be realized more uniformly.
  • the method can be carried out such that, at least in an axial section of the housing assigned to the respective axial section of the at least one insert, a circumferential geometry of the housing is deformed in dependence on the measured circumferential geometry of the at least one insert such that a radially between the housing and the housing at least one insert trained gap sets a predetermined gap profile in the circumferential direction.
  • the predetermined gap progression can take into account optimum compression of the bearing mat.
  • the predetermined gap profile can take into account anisotropic load limits of the respective insert. Since the achievable gap size correlates with the radial compression of the bearing mat and thus with the forces occurring during pressing, the load of the respective insert during deformation of the housing can be determined by specifying the gap dimension.
  • the respectively measured circumferential geometry of the respective insert can be assigned to predetermined circumferential segments of the insert, in which case, in addition, for the respective circumferential segment, an averaged peripheral geometry from those in the respective circumferential segment measured circumferential geometry values is determined.
  • the deformation of the housing is then also in circumferential segments which are assigned to the circumferential segments of the respective insert, wherein the deformation of the housing in the housing-side circumferential segments takes into account the averaged circumferential geometries.
  • This procedure takes into account in particular deformation tools distributed in the circumferential direction, arranged segmented moldings.
  • the detection and consideration of the circumferential geometry of the respective insert takes place at least in an axial section of the insert. It is clear that in other embodiments, several axial sections can be measured with respect to their circumferential geometry. Accordingly, a corresponding number of axial sections of the housing can then also be deformed during the deformation of the housing as a function of the respectively measured peripheral geometries. In principle, any resolution in the longitudinal direction is conceivable. For example, the complete outer contour of the respective insert may be e.g. be detected by so-called 3-D scanning. Thus, in addition, a longitudinal geometry of the respective insert during deformation of the housing can be taken into account.
  • An exhaust gas treatment device which is produced by the method according to the invention can be characterized, for example, by the fact that the housing has a cross-section adapted to the cross-section of the insert, even if the respective insert has an asymmetrical cross-section with respect to rotations about its longitudinal central axis.
  • the cross-section of the housing then shapes the respective asymmetry of the insert more or less exactly.
  • Ceramic monoliths the cell matrix of which has a lattice of mutually perpendicular webs, have a pressure load capacity that varies from the rotational position. Parallel to webs of the respective monolith is higher loadable than in the diagonal direction of the cells. The dependence of the compressive strength of the respective use of its rotational position can be taken into account when deforming the housing.
  • an exhaust gas treatment device which has been produced by the process according to the invention, in particular also characterized in that the housing is formed in an axial portion associated with the respective application so that adjusts a course in the circumferential direction for the radial gap geometry, one of the radial, with the rotational position varying pressure load capacity of the respective use dependent course taken in the circumferential direction of the radial compression of the bearing mat.
