摘要： 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 and advancing mixed gas flow in direction of the longitudinal axis as a mixed exhaust gas flow; and a second substrate being positioned within the interior of the housing downstream to the mixer arrangement, wherein the mixed exhaust gas flow being configured to flow through the second substrate in direction of the longitudinal axis.
