顆粒物氧化器（poc）

·通過(guò)其特殊的載體結(jié)構(gòu)使排氣通過(guò)多褶皺而不堵塞的通道，可以捕捉并氧化部分顆粒物；
·其突出的特點(diǎn)是其顆粒物的轉(zhuǎn)化效率可達(dá)到60%-70%以上（結(jié)合恰當(dāng)匹配的doc）；
·采用egr+doc+poc，輕型柴油車可達(dá)到國(guó)4標(biāo)準(zhǔn)；
·薄孔壁（約0.03mm）保證了低背壓；
·機(jī)械強(qiáng)度高，很好的導(dǎo)熱率，啟動(dòng)快；
·不會(huì)造成煙灰或顆粒的阻塞，不需要主動(dòng)再生設(shè)備，可表面涂覆催化劑，免維護(hù)。

·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.
