主要特點(diǎn) Main features
針對(duì)柴油車國(guó)三、國(guó)四及以上排放標(biāo)準(zhǔn),威孚公司開發(fā)了柴油車氧化型催化劑,使尾氣中的CO、HC、SOF的轉(zhuǎn)化率達(dá)到90%以上。通過(guò)控制稀土材料使用及涂層微觀結(jié)構(gòu),使DOC能以較低貴金屬用量達(dá)到良好的低溫活性。威孚公司DOC系列產(chǎn)品不僅可單獨(dú)使用,還能與POC或DPF配合使用,以協(xié)助顆粒捕集器的再生。
According to the CN III,IV and above Emission Standards for diesel vehicles(engines),WEIFU developed DOC product which can remove more than 90% of the CO,HC and SOF in the exhaust gas.By controlling the utilization of rare earth materials and micro structure of washcoat,DOC can possess well low-temperature activity with the low loading amount of precious metal.The DOC produced by WEIFU can not only be used alone but also be combined use with POC or DPF to help the regeneration process.
