針對(duì)汽油車國(guó)IV、國(guó)V、國(guó)VI排放標(biāo)準(zhǔn)，昱凱達(dá)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(dá)到95%以上。通過控制氧化鋁、儲(chǔ)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(guó)IV--10萬公里國(guó)V--16萬公里的耐久性要求。昱凱達(dá)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。
In response to the National IV, V, and VI emission standards for gasoline vehicles, Yukaida has developed a high-temperature resistant and highly active three-way catalyst (TWC), which achieves a conversion rate of over 95% for CO, THC, and NOx in exhaust gas. By controlling the microstructure of alumina and oxygen storage materials, TWC products can meet the durability requirements of China IV -100000 kilometers and China V -160000 kilometers with a lower amount of precious metals. The Yukaida TWC series products have more flexible applicability and can be installed in manifolds, tight couplings, or chassis positions.
