  • Publication number: 20250347240
    Abstract: A mixer assembly for mixing, in a mixing tube of an exhaust aftertreatment system, a reductant with an exhaust gas from an internal combustion engine may include a mixer and an electrically heated heating element. The mixer may be positioned in proximity to the reductant injector. The electrically heated heating element may be positioned in proximity to an impingement surface of the mixer. The reductant may directly impinge, after being injected, on the impingement surface causing the reductant to vaporize and mix with the exhaust gas forming a vaporized reductant and exhaust gas mixtures that flows along a flow path defined by the mixing tube. The vaporized reductant and exhaust gas mixture may be heated and further mixed by the electrically heated heating element.
