主要特點 Main features
針對CNG/LPG發(fā)動機(車)國三、國四排放標(biāo)準(zhǔn),威孚公司開發(fā)了不同應(yīng)用條件的催化劑。本技術(shù)采用的稀土材料作為助劑,使用少量貴金屬,利用陶瓷載體或鐵-鉻-鋁合金載體骨架,對尾氣中難以氧化的甲烷碳?xì)洌–H4)具有較低起燃溫度、較高的催化轉(zhuǎn)化效率。
According to the CN IV,V Emission Standards for CNG/LPG Engines,WEIFU has developed many catalysts in different applications.This technology uses special rare earth as addictive with precious metal in small amount and ceramic carrier and iron-chromium-aluminum alloy carrier.This structure helps to convert the inert CH4 in exhaust gas with lower ignition temperature and higher conversion rate.
