摘要： A mixing device includes a case surrounding a blowing section of a filter or a catalyst; an upper pipe segment having an opening facing a direction opposite to the blowing section and tilted relative to the vertical direction so that the more the upper pipe segment goes vertically downward, the closer it gets to the blowing section; a lower pipe segment bent from a lower end of the upper pipe segment and tilted relative to the vertical direction so that the more it goes vertically downward, the further away it gets from the blowing section, the lower pipe segment extending out from the case and connected to a selective catalytic reduction device; and an injector attached to the case and injecting a liquid additive toward an area faced by the opening, the area being located outside the upper pipe segment in the case.
