The invention relates to a system and a method for mixing exhaust gas and reductant. A mixing assembly for an exhaust aftertreatment system includes a mixing body, an upstream plate, a downstream plate, and a swirl plate. The mixing body includes an upstream mixing body opening and a downstream mixing body opening. The upstream mixing body opening is configured to receive exhaust gas. The upstreamplate is coupled to the mixing body. The upstream plate includes a plurality of upstream plate openings. Each of the plurality of upstream plate openings is configured to receive a flow percentage that is less than 50% of the total flow of the exhaust gas. The downstream plate is coupled to the mixing body downstream from the upstream plate in a direction of exhaust gas flow. The downstream plateincludes a downstream plate opening. The swirl plate is positioned between the upstream plate and the downstream plate and defines a swirl collection region and a swirl concentration region. 本申请涉及用于混合废气和还原剂的系统和方法。一种用于排气后处理系统的
