An exhaust-gas module A for an internal combustion engine, which exhaust-gas module has a base housing having a first side wall, at least one second side wall, an inlet for connection to the internal combustion engine and at least one outlet, wherein the inlet is arranged in the first side wall, and having multiple exhaust-gas purification components which are arranged in the base housing, wherein at least one SCR and/or one DOC are/is provided, wherein the at least one outlet is arranged in the second side wall and serves for the connection of an exhaust tailpipe of the internal combustion engine and/or alternatively for the coupling of an attachment housing, wherein the rest of the base housing, with the exception of the second side wall, is formed without outlets, wherein a connection contour with a circumferential contour Uwhich has a basic shape Gis provided for the connection of the attachment housing, wherein the connection contour delimits the second side wall at the edge, wherein at least one of the exhaust-gas purification components DPF, NH3, LNT, HOH is present in the base housing, and/or wherein at least one auxiliary component such as a mixer, an injector or a burner is present in the base housing.

Exhaust-gas module for an internal combustion engine

An exhaust-gas mixing pipe for admixing additive into an exhaust-gas stream of a combustion engine. The housing wall has multiple rows, arranged over a circumference U, of openings through which gas can flow into the interior of the pipe, wherein the at least one opening of a row forms in each case one stage M characterized according to its size by the average opening cross section Q of the openings, wherein the sum of all the opening cross sections Q of all the openings of all the rows of the exhaust-gas mixing pipe is equal to SQ. In that context, at least one first-order stage M, is provided, wherein stage Mhas openings having an average opening cross section Q. At least one second-order stage M, is provided, with openings having an average opening cross section Q, where Q&#x3e;=f Q, where 5&#x3c;=f&#x3c;=25.
