The invention relates to an exhaust gas aftertreatment apparatus (1) for a vehicle (2), in particular a motor vehicle, comprising: at least one tank (3) for storing and providing a liquid exhaust gas aftertreatment agent; at least one controllable conveying apparatus (5) for conveying the exhaust gas aftertreatment agent; at least two injection devices (6, 7) arranged at different heights, for injecting the exhaust gas aftertreatment agent into an exhaust gas; and at least one conveying line (9) for connecting the tank (3) to at least two injection devices (6, 7), wherein the conveying line (9) has at least one branching point (10), at which the conveying line (9) is divided into a first sub-line (11) connected to at least one first of the injection devices (6) and a second sub-line (12) connected to at least one second of the injection devices (7). At least one longitudinal portion (13) of the first sub-line (11) and at least one longitudinal portion (14) of the second sub-line (12) are arranged running horizontally and in parallel with one another.

    本发明涉及一种用于车辆(2)、尤其是机动车的废气后处理装置(1),其具有至少一个用于储存和提供液态废气后处理剂的箱(3)、用于输送废气后处理剂的至少一个可操控的输送装置(5)、用于将废气后处理剂喷射到废气中的至少两个以不同高度布置的喷射设备(6,7)、以及用于将所述箱(3)与至少两个喷射设备(6,7)连接的至少一个输送管路(9),其中,所述输送管路(9)具有至少一个分支部位(10),在所述分支部位处,所述输送管路(9)分为与至少一个第一喷射设备(6)连接的第一子管路(11)和与至少一个第二喷射设备(7)连接的第二子管路(12)。本发明设置,所述第一子管路(11)的至少一个纵向区段(13)和所述第二子管路(12)的至少一个纵向区段(14)水平地并且彼此平行延伸地布置。
