摘要：
An apparatus, system, and method are disclosed for regenerating an exhaust gas treatment device. A controller module 115 directs an injector 110 to provide reductant to an exhaust gas treatment device 105 over a plurality of rich intervals during a regeneration cycle. In addition, the controller module 115 directs the injector 110 to reduce the reductant provided to the exhaust gas treatment device over a lean interval between the rich intervals to create a lean environment within the exhaust gas treatment device 105. In one embodiment, the controller module 115 modifies the reductant provided during each rich interval, the number of rich intervals, the length of the rich intervals, and the length of the lean intervals in response to an exhaust gas state.

公开了用于再生废气处理装置的装置，系统和方法。 控制器模块115引导注射器110在再生循环期间通过多个富间隔向废气处理装置105提供还原剂。 此外，控制器模块115引导注射器110以在富间隔之间的稀薄间隔减小提供给废气处理装置的还原剂，以在废气处理装置105内产生贫化环境。在一个实施例中，控制器模块 115改变在每个富间隔期间提供的还原剂，富间隔的数量，富间隔的长度以及响应于废气状态的稀薄间隔的长度。
