摘要： The invention concerns a procedure to heat a reducing agent generation system of an exhaust gas aftertreatment system of an internal combustion engine by combustion of fuel, whereby the reducing agent is produced for the selective catalytic reduction of nitrogen oxides in the exhaust gas of the internal combustion engine in the intermittently operated reducing agent generation system, whereby the reducing agent generation system consists of a plasma burner, a mixing chamber located downstream or upstream from the plasma chamber, an oxidation reformation unit as well as a nitrogen oxide storage/ammonia production unit and whereby nitrogen oxide is produced in a plasma in the plasma burner. The invention concerns additionally a corresponding device.The task of the invention concerning the procedure is thereby solved, in that the combustion of the fuel is ignited by the plasma. For this reason, the heating of the catalytic components required at the start of the reducing agent generation system results through the combustion of fuel by means of a burner functionality, which consists of a fuel metering mechanism and the existing plasma burner. A special heating burner as an auxiliary mechanism can be omitted.
摘要翻译：本发明涉及通过燃料燃烧来加热内燃机的废气后处理系统的还原剂产生系统的方法，由此制备用于选择性催化还原内燃机废气中的氮氧化物的还原剂所述还原剂产生系统由等离子体燃烧器，位于等离子体室下游或上游的混合室，氧化重整单元以及氮氧化物储存/氨生产单元组成，由此在等离子体燃烧器中的等离子体中产生氮氧化物。本发明另外涉及相应的装置。从而解决了关于该过程的本发明的任务，因为燃料的燃烧被等离子体点燃。因此，在还原剂生成系统开始时所需的催化剂组分的加热，是通过燃料功能燃烧而形成的，燃烧器功能由燃料计量机构和现有的等离子燃烧器组成。可以省略作为辅助机构的特殊加热燃烧器。
