Abstract

A mixing device for integration into an exhaust pipe of an internal combustion engine and for mixing an exhaust gas stream (T), which device is formed from a housing having a tubular wall and a mid-axis that can be aligned parallel to the exhaust pipe and from an intermediate wall which is aligned transversely with respect to the mid-axis, wherein the intermediate wall divides the housing and has an inflow side and an outflow side, wherein at least one inflow opening (E1) is provided in the intermediate wall, via which the exhaust gas stream (T) can at least partly flow from the inflow side of the intermediate wall to the opposite outflow side of the intermediate wall, wherein the at least one inflow opening (E1) is placed eccentrically with respect to the mid-axis and is brought close to a wall section (W1) of the tubular wall, wherein a flow guide element (S2) having a longitudinal axis (L2) is provided on the outflow side, which at least partly bounds a mixing chamber with the intermediate wall and by an at least partial deflection of the exhaust gas stream (T) in a radial direction in relation to the mid-axis can be effected, wherein the flow guide element (S2) has at least two outflow openings (A1, A2) and, by the flow guide element (S2), the exhaust gas stream (T) coming from the inflow opening (E1) can be guided to the at least two outflow openings (A1, A2), wherein the outflow openings (A1, A2) are placed eccentrically with respect to the mid-axis and brought close to a common wall section (W2) of the tubular wall, wherein the wall section (W2) is arranged opposite to the wall section (W1) with respect to the mid-axis, and wherein the outflow openings (A1, A2) are arranged on opposite sides of the flow guide element (S2) with respect to the longitudinal axis (L1, L2), wherein, with respect to the mid-axis, the first partial stream (T3) can be can at least partly guided in the anticlockwise direction and a second partial stream (T4) can at least partly be guided in the clockwise direction out of the outflow openings (A1, A2).
