主要特點(diǎn) Main features
針對柴油車國三與國四排放標(biāo)準(zhǔn),威孚公司開發(fā)了選擇性催化還原催化劑(SCR)。該催化劑以氨或尿素水溶液為還原劑將排氣中的NOx還原為無害的N2和水。此催化劑具有良好的NOx轉(zhuǎn)化效率和耐久性。
According to the CN IV,V Emission Standards for diesel vehicles(engines),WEIFU developed the SCR catalyst.This catalyst can use ammonia or urea solution as reductant to convert NOx which in the exhaust gas to harmless N2 and H2O.WEIFU SCR catalyst is superior in NOx conversion efficiency and durability.
