摘要： A device for aftertreatment of exhaust gas includes: a prechamber having an exhaust gas inlet; a main chamber; a mixing device, in which the exhaust is mixable with an additive; and an intermediate device, via which a partial exhaust gas flow is deliverable from the prechamber to the mixing device. The intermediate device has swirl elements configured to reverse the direction of swirl of swirled exhaust gas flow generated in the prechamber as the exhaust gas overflows into the interior of the intermediate device, and/or the prechamber is configured to impel a first partial exhaust gas flow in a direction of swirl, and the main chamber is configured to impel a second partial exhaust gas flow from the prechamber in a direction of swirl, the direction of swirl of the exhaust gas in the prechamber being opposed to the direction of swirl of the exhaust gas in the main chamber.
