Exhaust aftertreatment filter with particulate distribution pattern |
摘要 |
<p>An exhaust aftertreatment filter and method is provided for filtering engine exhaust. Varying cell size is provided to spread trapped contaminant particulate along a distribution pattern reducing heat concentration and the risk of melting during regeneration, to minimize hot-spot meltdown otherwise caused by high density concentration of trapped particulate during regeneration. Cell size is varied by varying volume and/or height and/or width and/or length. Tapering of cells is also provided to change the cross-sectional area from the upstream to the downstream end. <IMAGE></p> |
