柴油氧化型催化剂 Diesel Oxidation Catalyst(DOC)
主要特点 Main features
针对柴油车国三、国四及以上排放标准,威孚公司开发了柴油车氧化型催化剂,使尾气中的CO、HC、SOF的转化率达到90%以上。通过控制稀土材料使用及涂层微观结构,使DOC能以较低贵金属用量达到良好的低温活性。威孚公司DOC系列产品不仅可单独使用,还能与POC或DPF配合使用,以协助颗粒捕集器的再生。
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.
