    摘要： [Problem] To suppress the generation of turbulent flow that does not contribute to the purification of exhaust gas to decrease the pressure loss, and to decrease the amount of the catalyst applied to the region that does not contribute to the purification of exhaust gas.
    [Solution] A honeycomb core for carrying a catalyst, comprising a flat metal foil and a corrugated metal foil, the flat metal foil and the corrugated metal foil being layered, wherein the corrugated foil is configured by repeating a concavo-convex shaped part including a first top surface that is in contact with one of the flat foils adjacent in a layering direction, a second top surface that is in contact with another flat foil adjacent in the layering direction and is disposed at a position where the second top surface avoids the first top surface as viewed in the layering direction, and an inclined leg surface that has one end connected to the first top surface through a first bent part and another end connected to the second top surface through a second bent part, and extends in a direction inclined with respect to the first top surface and the second top surface, and has an offset part having different wave phases between front and rear in an axial direction of the honeycomb core,the first bent part and the second bent part each have a R shape,a radius of curvature R1 of an inner edge of the first bent part and a radius of curvature R2 of an inner edge of the second bent part satisfy the following conditional expressions (1) and (2), respectively, and a separation distance h in the layering direction between the first top surface and the second top surface and a separation distance S between a pair of the inclined leg surfaces connected to the first top surface through the first bent parts satisfy the following conditional expression (3) :0.02 (mm) ≤ R1 ≤ 2.0 (mm) (1),0.02 (mm) ≤ R2 ≤ 2.0 (mm) (2), and 1.5 ≤ S/h ≤ 10 (3).

    摘要： The invention relates to a honeycomb body (1) wrapped and/or layered from layers (2, 3), having a geometric center axis (4), a cavity (5) arranged rotationally symmetrically around the center axis (4), and an outer lateral surface (6), wherein each layer (2, 3) extends approximately concentrically around the center axis (4), wherein at least one of the layers (2) is at least partially structured, so that the layers (2, 3) form a plurality of channels (7) through which a fluid can flow, which channels extend from the cavity (5) outward to the outer lateral surface (6) at a non-right cone angle (α) to the center axis (4), and wherein the channels (7) have a channel cross-section (7i, 7a) that changes in the course of the channels from the inside to the outside. The special form results in particular in that at least one structured layer (2) is arranged in alternation with at least one intermediate layer (3; 8; 13; 23; 33), wherein the two layers are helically layered on each other and wherein the structure height (H) of the structured plate layer (2), which structure height forms the channels (7), is substantially constant and the channel cross-sectional areas (7i, 7a) increase from the inside to the outside. The intermediate layer (3) can be made of simple wires (8) or of specially cut or folded smooth plates (13; 23; 33).

    摘要： A unit (4) for reducing the emission of pollutants contained in exhaust gas is disclosed. It comprises a frame and a stack (2) comprising a plurality of layers (20) of corrugated sheet material. The stack (2) is formed by alternately folding back and forth an unfolded strip (1). The unfolded strip (1) has a length (100) corresponding to the length (200) of the layers (20) and a width (101) corresponding to a multiple of the width (201) of the layers (20). The corrugations (10) of the unfolded strip (1) run in a direction including an angle ( α ) different from zero with the direction of the length (101) of the strip (1), so that after folding the strip (1) the corrugations of the adjacently arranged layers (20) come to lie on one another crossing each other at a crossing angle ( β ) which is twice as much as the angle ( α ). The folds (21) connecting the adjacently arranged layers are welded to the side walls (31, 33) of the frame along welding seams (40, 41).
