A configuration for treating exhaust gases of an internal combustion engine having a predetermined displacement volume, includes an exhaust gas recirculation line. Exhaust gas flowing through the exhaust gas recirculation line interacts with a turbocharger. A screening layer is provided in the exhaust gas recirculation line upstream of the turbocharger. The screening layer is larger than an average cross section of the exhaust gas recirculation line. A motor vehicle having at least one such configuration is also provided.

A method for gluing and brazing a honeycomb structure includes at least one partially structured foil with a pitch and a wave height. The method includes the steps of choosing a mean brazing material diameter of a powder brazing material, said diameter being 15% smaller than the height of the wave; determining a minimum thickness of the glue strip according to equation; gluing at least partially structured foil within the width of the glue strip on at least part of the wave crests formed by the undulation; brazing the honeycomb structure. The invention also relates to a corresponding honeycomb structure that ensures satisfactory joint connections even when said structure is used in the exhaust systems of automobiles.

Honeycomb structure and method for applying adhesive and brazing material to the structure

A method for producing aluminum-containing honeycomb bodies includes providing at least partly structured aluminum-based metal foils. The at least partly structured metal foils are stacked and/or wound to form a honeycomb structure having passages. The metal foils are heated from an open end face of the passages with at least one radiant heater. The honeycomb structure is heated in at least one subregion in such a way that the at least one subregion has a temperature between approximately 450&#xb0; C. and approximately 600&#xb0; C. after approximately 2 seconds to approximately 30 seconds. The metal foils are connected together in the at least one subregion by technical joining.

Process for producing aluminum-containing honeycomb bodies using radiant heaters

A process and an apparatus for producing a honeycomb body include forming a metallic honeycomb structure having cavities through which a fluid can at least partially flow, and bringing at least one end side of the honeycomb structure into contact with a metallic melt having a lower melting point than the metallic honeycomb structure. The process and the apparatus allow layers of sheet metal to be intimately and permanently joined in an advantageous manner in joining regions by placing at least one end face of a honeycomb structure of the honeycomb body in contact with a metallic melt which has a lower melting point than the honeycomb structure and contains aluminum, for example. A honeycomb body which is produced by the method or the apparatus is also provided.

A process for producing a metallic layer includes forming structures at least in subregions of the metallic layer. The structures have corrugation troughs and corrugation peaks, an upper bearing surface formed at least in part from the peaks, and a lower bearing surface formed at least in part from the troughs. The metallic layer is formed with at least a first region having a first thickness and a second region having a second thickness, different than the first thickness. The structures are formed, in longitudinal direction, independently of the thickness, with at least one of the upper and lower bearing surfaces in the regions being substantially aligned in longitudinal direction in vicinity of at least one of the peaks and the troughs. A metallic layer with regions of varying material thickness and a honeycomb body produced at least partly from such metallic layers, are also provided.
