Abstract: An exhaust gas aftertreatment system includes an exhaust conduit having an inner wall, and a mixer mounted inside the exhaust conduit. The exhaust conduit defines a passage along a length of the exhaust conduit for exhaust gas flow therethrough. The mixer includes first bars coupled to second bars. Each first bar includes deflectors on a straight section, a first end, and a second end. The one or more of the first bars include a curved section at the first end and the second end. Each second bar includes a straight section, a third end, and a fourth end. The one or more of the second bars include a curved section at the third end and the fourth end. The mixer is mounted inside the exhaust conduit by coupling the curved section of the first bar and the second bar to the inner wall of the exhaust conduit.
