Abstract: The invention relates to a structure for filtering particle-laden gases, comprising an assembly of elements of the honeycomb type linked by a joint or seal, each element incorporating a set of adjacent ducts or channels 20 of mutually parallel axes and separated by porous walls, which ducts are closed off by plugs at one or other of their ends so as to define entry chambers that open onto a gas intake face and exit chambers opening onto a gas discharge face 25, in such a way that the gas to be filtered passes through the porous walls, said structure being characterized in that its geometrical centre, in a cross section of the structure perpendicular to its main axis, does not correspond to a symmetry element of an element or of a group of elements 30 in the assembly.

Abstract: The invention relates to a structure for filtering particle-laden gases, of the honeycomb type and comprising an assembly of longitudinal adjacent channels of mutually parallel axes, separated by porous walls, said structure being characterized in that at least one, and preferably all, of the walls joining two vertices of a channel and separating the latter from a contiguous channel has, in cross section and with respect to the center of said channel, at least one concavity and at least one convexity.

Abstract: The invention relates to a method for the calibration and/or management of an exhaust line of a motor vehicle comprising a particle filter (X), said method comprising an initial step of measuring, over a representative population of the filter, the increase in the loss of load generated by a limited load of soot particles present in a filter, that is the threshold for the triggering of a filter regeneration phase; a step of measuring, in the absence of soot particles, the loss of specific load of the filter (X); and a step of determining, on the basis of the values obtained in steps a) and b), a limited value for the loss of load, that is the threshold for the triggering of a regeneration phase. The invention also relates to a system for managing an exhaust line comprising means for implementing said method.

Abstract: The invention relates to a honeycomb monolithic element for the filtration of particles, characterized in that the peripheral channels forming part of the outer wall of said element are configured to help in the formation of an outer wall whose inner face is substantially flat over the whole length of the element and in that said flat wall also has an increased thickness at the corners, so that, on a cross section, the ratio R of the thickness Ec of the wall, measured along the bisecting line of the angle at a corner of the element, over the minimal thickness Emin of said wall is greater than 1.5.
