用于排气设施的混合器
摘要：
本发明涉及一种用于内燃机的排气设施的混合器，具有：管部段，所述管部段沿环周方向包围能够由所述废气流穿流的流动横截面并且所述管部段沿轴向方向从该管部段的第一轴向侧延伸至该管部段的第二轴向侧；多个导向叶片，所述导向叶片至少在各轴向侧之一上突出于所述管部段，使得所述导向叶片伸入到所述流动横截面中，其特征在于，所述导向叶片至少分为第一导向叶片组和第二导向叶片组，各导向叶片组沿所述环周方向位错地设置，所述第一导向叶片组的导向叶片相对于所述第二导向叶片组的导向叶片轴向位错地设置。本发明还涉及一种具有这种混合器的、用于内燃机的排气设施的反应剂输送装置以及一种具有这种反应剂输送装置的、用于内燃机的排气设施。
摘要（英）：

An exhaust system mixer (12) mixes a reactant with an exhaust gas flow (3) and includes a pipe section (13), which borders a flow cross section (16), through which the exhaust gas flows (3), in the circumferential direction (17), and which extends in an axial direction (18) from a first axial side (19) to a second axial side (20), and a plurality of guide blades (14, 15), which project from the pipe section (13) at least on one of the axial sides (19, 20), so as to protrude into the flow cross section (16). Guide blades (14, 15) on an axial side, which follow each other in the circumferential direction (17), include a first guide blade group (21), arranged on the respective axial side (19, 20), axially offset in relation to the guide blades (15) of the second guide blade group (22), to reduce a pressure drop.
