5.选择性催化剂还原SCR为了满足不断提高的尾气排放规定,宝马在当前柴油发动机上采用以下技术,从而在废气再处理过程中还原氮氧化物:氮氧化物存储式催化转换器NSC选择性催化剂还原SCR选择性催化剂还原SCR是一项宝马高效动力措施,可确保现代柴油机车辆以经济方式运行。SCR系统通过向废气中配给一种还原剂(Ad-Blue~)将氮氧化物还原至最低程度。在此不会影响实际燃
5. Selective Catalytic Reduction of SCR In order to meet the evolving exhaust emission regulations, BMW uses the following technologies on current diesel engines to reduce nitrogen oxides in exhaust gas aftertreatment: Nitrogen Oxides Storage Catalytic Converters NSC Selective Catalysts Reduction of SCR Selective Catalysts SCR reduction is an efficient BMW initiative to ensure that modern diesel vehicles operate economically. The SCR system reduces nitrogen oxides to a minimum by deploying exhaust gas with a reducing agent (Ad-Blue®). This does not affect the actual burning
