Abstract

An influx chamber (1) for a catalytic converter (2) comprising a body (3) having a side surface (31) and two front faces (32, 33) spaced apart from and opposite to each other, with the side face (31) und a first front face (32) being made from a material impermeable to exhaust gases (4), and a second front face (33) being permeable to exhaust gases (4). The side face (31) comprises an inlet opening (34) for reducing agent (5) loaded exhaust gases (4). The influx chamber (1) further comprises an inlet pipe (6) made from a material impermeable to exhaust gases (4) and penetrating the side face (31) of the body (3) in the region of the inlet opening (34). The longitudinal axis (LR) of the inlet pipe (6) is disposed in a plane perpendicular to the longitudinal axis (LG) of the body (3). The inlet pipe (6) further extends inside the body (3) along the longitudinal axis of the inlet pipe (6) for at least half of the diameter (DG) of the body (3), and in particular for the whole of the diameter (DG) of the body (3). The inlet pipe (6) has a baffle plate (61) at its end located inside the body (3), the baffle plate (61) being made from a material impermeable to exhaust gases (4). The inlet pipe (6) further has at its end located inside the body (3) and adjacent to the baffle plate (61) a discharge opening (62) that opens a radial wall of the inlet pipe (6). Figure: 1
