颗粒物氧化器(POC)
·通过其特殊的载体结构使排气通过多褶皱而不堵塞的通道,可以捕捉并氧化部分颗粒物;
·其突出的特点是其颗粒物的转化效率可达到60%-70%以上(结合恰当匹配的DOC);
·采用EGR+DOC+POC,轻型柴油车可达到国4标准;
·薄孔壁(约0.03mm)保证了低背压;
·机械强度高,很好的导热率,启动快;
·不会造成烟灰或颗粒的阻塞,不需要主动再生设备,可表面涂覆催化剂,免维护。
·The special substrate structure of POC forces exhaust gas flowing through multi-fold while non-blocking channels, capturing and oxidizing part of PM emissions;
·Conversion efficiency can reach over 60%-70% (with appropriately matched DOC);
·EGR + DOC + POC is a solution for light duty diesel vehicles reaching Euro IV;
·Low wall thickness (~0.03mm) ensures low back pressure;
·High mechanical strength, good thermal conductivity, fast activating;
·No blocking by ash or particulates, no need for active regeneration, can be coated, life time maintenance free.
