Abstract: An apparatus for aftertreatment of exhaust gas including a housing having a longitudinal axis that extends between a first end and a second end of the housing; an exhaust inlet being positioned at a portion of the first end of the housing for entering exhaust gas flow into the interior of the housing; a first substrate being positioned within the interior of the housing downstream to the exhaust inlet, wherein the exhaust gas flow being configured to flow through the first substrate in direction of the longitudinal axis; mixer arrangement being positioned within the interior of the housing downstream to the first substrate and including: first flow guide arrangement configured to guide the exhaust gas flow to rotating and advancing gas flow in direction of a crosswise axis perpendicular to the longitudinal axis; a reactant inlet for dispensing reactant to the rotating and advancing gas flow, the reactant configured to mix with the exhaust gas; and second flow guide arrangement configured to guide the rotating

Abstract: An apparatus for aftertreatment of exhaust gas includes a housing configured to define an inner cavity; an exhaust inlet arranged to the housing for entering exhaust gas flow to the inner cavity; a mixer unit arranged in the inner cavity to dispense a reactant to the exhaust gas flow; a mixing device, located downstream of the mixer unit, to evenly mix the reactant to the exhaust gas flow. The mixing device includes: a toroidal cylinder to receive the exhaust gas flow from the mixer unit via a solid tubular element, wherein the solid tubular element is in a centric manner to a first base of the toroidal cylinder for guiding the exhaust gas flow led into the toroidal cylinder to swirl inside the toroidal cylinder; and an exhaust outlet arranged to a curved side of the toroidal cylinder, to exit the exhaust gas flow from the mixing device.
