主要特點 Main features
針對汽油車國三、國四排放標(biāo)準(zhǔn),威孚公司開發(fā)了耐高溫、高活性三元催化劑(TWC),使尾氣中的CO、THC與NOX轉(zhuǎn)化率達到90%以上。通過控制氧化鋁、儲氧材料的微觀物理結(jié)構(gòu),使得TWC產(chǎn)品以較低貴金屬用量滿足國Ⅳ--10萬公里國Ⅴ--16萬公里的耐久性要求。威孚公司TWC系列產(chǎn)品具有更靈活的適用性,可安裝在歧管、緊耦合或底盤位。 According to the CN IV,V Emission Standards for gasoline cars,WEIFU has developed heat-resistant and high active TWC with 90% convertion rate fo CO,THC and NOX.By controlling the micro physical structure of alumina and oxygen-storage materials,WEIFU uses less precious metal to meet the durability requirements ie.100,000 km for CN IV and 160,000 km for CN V.The TWC serial can be flexibly installed to manifold,tight coupling or bottom position.
