用于将反应剂馈入内燃机排气流中的反应剂馈入设备
摘要：
本发明涉及一种用于将反应剂馈入内燃机排气流中的反应剂馈入设备，其包括：反应剂馈入壳体(16)，其具有被壳体壁(18)包围的反应剂馈入空间(20)，所述壳体壁(18)包括一个能关于排气流动方向(A)定位在上游的流入壁区域(30)、一个能关于排气流动方向(A)定位在下游的流出壁区域(32)和在流入壁区域(30)和流出壁区域(32)之间的两个侧壁区域(34、36)，在至少一个侧壁区域(34、36)中和/或在流出壁区域(32)中设置至少一个通流口(72、74、76)；反应剂喷入装置(28)，其用于将反应剂沿反应剂馈入方向(E)喷入反应剂馈入空间(20)中、到能加热的反应剂馈出元件(48)上。
摘要（英）：

The invention relates to a reactant introduction device for introducing reactant into an exhaust gas stream of an internal combustion engine. The reactant introduction device includes a reactant introduction housing (16) with a reactant introduction space (20) surrounded by a housing wall (18). The housing wall (18) includes an incoming flow wall area (30) positioned upstream in relation to an exhaust gas flow direction (A), an outgoing flow wall area (32) positioned downstream, in relation to the exhaust gas flow direction (A) and two side wall areas (34, 36) between the incoming flow wall area (30) and the outgoing flow wall area (32), at least one flow-through opening (72, 74, 76) is provided in at least one side wall area (34, 36) or/and in the outgoing flow wall area (32); and a reactant injection device (28) injects reactant into the reactant introduction space (20) in a reactant introduction direction (E) onto a heatable reactant release element (48).
