摘要:
In a diesel particulate trap, a filter (4), which is formed with a three-dimensional mesh-like structure porus body (fig. 13) made of a heat resistant metal or metal unwoven cloth, is placed in a case (1) containing therein a trap connected to an exhaust of a diesel engine. The filter surfaces of the filter are parallel to the direction of a flow of exhaust gas. The pore diameter, thickness, a material packing density or a mass diameter of the filter is varied in the lengthwise of the filter. With this unique structure, the flow velocity of the exhaust gas passing through the filter (4) is uniform over the entire length of the filter. Therefore the particulate collecting or trapping efficiency is improved. Further, the filter, when bearing catalyst thereon, has an additional function to remove poisonous gas components from the exhaust gas.
摘要(中):
在柴油机颗粒捕集器中,将由耐热金属或金属无纺布制成的三维网状结构多孔体(图13)形成的过滤器(4)放置在壳体(1)中, 其中包含与柴油发动机的排气口连接的捕集器。 过滤器的过滤表面平行于废气流的方向。 过滤器的纵向上过滤器的孔径,厚度,材料填充密度或质量直径是变化的。 通过这种独特的结构,通过过滤器(4)的废气的流速在过滤器的整个长度上是均匀的。 因此颗粒收集或捕集效率得到改善。 此外,过滤器在其上承载催化剂时还具有从废气中去除有毒气体成分的附加功能。
