摘要
影响国六柴油车尾气排放污染物的部件主要有NOX上游温度传感器和SCR上游温度传感器、EGR阀、尿素泵、DPF等。它们专门用来处理排放出来的污染物,通过三元催化器的处理后,一氧化碳会被氧化成二氧化碳和水,另外的氮氧化合物被转化为氮气和氧气。
The components that affect the exhaust emissions of National VI diesel vehicles mainly include NOX upstream tempera-ture sensors and SCR upstream temperature sensors,EGR valves,urea pumps,DPF,etc.They are used specifically to treat the pollut-ants emitted.After being treated by a three-way catalyst,carbon monoxide is oxidized into carbon dioxide and water,while other nitro-gen oxides are converted into nitrogenand oxygen.
