Abstract: A mixer comprises a tubular housing defining a longitudinal axis along which exhaust gas flows. Injected reductant flows along an injection axis that extends at a non-parallel angle to the longitudinal axis. A first flow guide element extends across and blocks a portion of the tubular housing and includes a first aperture extending therethrough. The first flow guide element is positioned upstream from the reductant inlet such that exhaust gas flowing through the first aperture is impinged by the reductant. A second flow guide element is positioned downstream from the first flow guide element and fixed to the first flow guide element to define a mixing chamber in which injected reductant and exhaust gas mix. An intermediate wall is integrally formed with one of the first and second flow guide elements. The other of the first and second flow guide elements is fixed to the intermediate wall.

Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The reductant inlet is positioned on a first side of the tubular housing and oriented to direct injected reductant along an injection access that extends transversely to a longitudinal axis. A first flow guide element is shaped as a sheet including a first aperture extending therethrough as well as a surface facing upstream. Exhaust gas flowing through the first aperture is impinged by the injected redundant. A second flow guide element is shaped as a sheet, positioned downstream from the first flow guide element and fixed to the first flow guide element to define a mixing chamber between the first flow guide element and the second flow guide element in which the injected redundant and the exhaust gas mix.

Abstract: A mixer assembly comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The tubular housing defines a longitudinal axis along which exhaust enters the housing. The reductant inlet is positioned on a first side of the tubular housing. An upstream element covers approximately one-half of the cross sectional area of the enhaust gas inlet and is positioned upstream of the reductant inlet. An upstream surface of the upstream mixing element directs exhaust gas flow transversly toward the reductant inlet. A downstream mixing element along with the upstream mixing element at least partially defines a reductant receiving duct in which injected reductant and exhaust gas mix.

Abstract: The subject matter of the invention is apparatuses for the aftertreatment of the exhaust gases of diesel engines. The apparatus comprises a pipe (2), through which the exhaust gases flow, a nozzle for injecting an additive into the pipe (2), and a mixing section (3) which is arranged behind the nozzle. A mixing pipe (20) is inserted into the pipe (2) adjacently to the nozzle. Said mixing pipe (20) is provided with large-area perforations (22) on the circumference, is seated in the pipe (2) with a radial spacing, has a closure cover (25) at its end with a receptacle (26) for the nozzle and, at its other end, has a funnel-shaped widened portion (23) which bears against the pipe (2) at least in regions.

Abstract: A system for applying secondary fluids to vehicular exhaust after-treatment apparatus utilizes a mixing chamber coupled for receipt of a portion of the vehicle's exhaust flow. A source of secondary fluid is coupled to the mixing chamber and a fluid distribution element is positioned in a mean exhaust flow conduit upstream of the exhaust after-treatment apparatus. The fluid distribution element presents a preselected pattern of fluid flow toward an upstream face of the after-treatment apparatus.
