包括氨气和氢气生成的排气后处理系统
摘要：
本发明提供一种后处理系统，其包括提供在排气通道中的排气处理部件、承载水溶液试剂的储箱、以及与该储箱连通并被配置成用于从该储箱接收该水溶液试剂的电化学室。该电化学室被配置成用于将水溶液试剂转换成第一排气处理流体和第二排气处理流体。控制器与该电化学室连通。该控制器被配置成用于改变这些电化学室所生成的第一排气处理流体和第二排气处理流体各自的量和/或成分。注入器与该电化学室和排气通道连通，并且被配置成用于从该电化学室接收该第一排气处理流体或该第二排气处理流体中的一者，并且将这一排气处理流体定量给送到该排气通道中该排气处理部件上游的位置处。
摘要（英）：

An after-treatment system is provided and includes an exhaust treatment component provided in an exhaust passage, a tank carrying an aqueous reagent, and an electrochemical cell in communication with the tank and configured to receive the aqueous reagent therefrom. The electrochemical cell is configured to convert the aqueous reagent into a first exhaust treatment fluid and a second exhaust treatment fluid. A controller is in communication with the electrochemical cell. The controller is configured to vary amounts and/or composition of each of the first exhaust treatment fluid and the second exhaust treatment fluid produced by the electrochemical cell. An injector is in communication with the electrochemical cell and the exhaust passage, and is configured to receive one of the first exhaust treatment fluid or the second exhaust treatment fluid from the electrochemical cell, and dose the one exhaust treatment fluid into the exhaust passage at a location upstream from the exhaust treatment component.
