Abstract: The invention relates to an exhaust gas cleaning device (2) for an internal combustion engine, with an injection module (1) for a reduction agent, particularly urea, having a housing (3) with a main chamber (4), in which main chamber (4) a mixing tube (5) is arranged downstream of a metering chamber (6) into which the reduction agent is injected by means of an injection device (11). The injection module (1) for exhaust gas has at least one first inlet (8) into the main chamber (4) and at least one first outlet (7b) out of the mixing tube (5). In order to achieve a high exhaust gas quality in as simple and space-saving a manner as possible, the metering chamber (6) has at least one second inlet (12) for exhaust gas, the main chamber (4) has at least one second outlet (9) for exhaust gas, and the main chamber (4) is separated in a gas-tight manner from the metering chamber (6) and from the interior (5a) of the mixing tube (5).
