    • The invention relates to an exhaust gas aftertreatment system particularly for a self-ignition internal combustion engine (1) having a catalytic converter and/or particulate filter inserted into a housing and associated with a burner (6) arranged upstream in an exhaust gas line (7), to which fuel can be supplied, and combustion air can be supplied via a combustion air line. The invention further relates to a method for operating an exhaust gas aftertreatment system of said kind. According to the invention, an exhaust gas aftertreatment system and a method for operating a system of said kind are provided, which are improved regarding the operation of the internal combustion engine (1). This is achieved in that the combustion air line (5) is connected to a crankcase ventilation line (2) of the internal combustion engine or that according to the claimed method the combustion air is the crankcase ventilation gas of the internal combustion engine (1). Thus advantageous use or disposal of the crankcase ventilation gas is achieved.
    • 本发明涉及一种特别用于自燃内燃机(1)的废气后处理系统,该自燃内燃机(1)具有插入壳体中的催化转化器和/或微粒过滤器并且与布置在排气管线(6)的上游的燃烧器 燃料可以供给到其中,并且燃烧空气可以经由燃烧空气管路供应。 本发明还涉及一种用于操作所述类型的排气后处理系统的方法。 根据本发明,提供了一种废气后处理系统和用于操作所述类型系统的方法,所述系统在内燃机(1)的操作方面得到了改进。 这是通过将燃烧空气管线5连接到内燃机的曲轴箱通风管线2或根据所要求保护的方法将燃烧空气作为内燃机1的曲轴箱通风气体来实现的, 。 因此实现了曲轴箱通风气体的有利使用或处置。
