2013摘要：具有六边形单元几何形状的基于钛酸铝（AT）的柴油颗粒过滤器（DPF）先前已被呈现为具有极低压降的有前途的介质，这来自于DPF的特定六边形通道。在发动机台架上的试验研究表明，六边形单元结构的AT过滤器具有与标准单元结构的AT过滤器不同的燃烧特性。为了理解这种行为，在过滤器内部进行了微观尺度的直接观察。研究发现，六边形通道在颗粒物上诱导了多个台阶
2013 ABSTRACT : Aluminum titanate (AT)-based Diesel Particulate Filter (DPF) with hexagonal cell geometry has previously been presented as a promising media showing extremely lower pressure drop, coming from its specific hexagonal channels of DPF. In addition these AT characteristics, the investigation on an engine bench verified that AT filter with the hexagonal cell structure exhibited different combustion behavior from the one with the standard cell structure. To understand this behavior, direct observation inside the filter on its microscopic scale was carried out. It was found that the hexagonal channels induced multiple steps on particulate matter
