Various methods are provided for operating an emission control device. In one example, a method for an emission control device including a catalyst and a filter comprises passively regenerating the filter, and adjusting, via a controller, a duration of active regeneration of the filter based on an oxygen storage capacity of the emission control device. 本发明提供了用于操作排放控制装置的各种方法。在个示例中，种用于包括催化剂和过滤器的排放控制装置的方法包括被动再生过滤器，以及基于排放控制装置的氧气储存容量经由控制器调节过滤器的主动再生的持续时间。
