摘要： The exhaust gas purification device according to the present invention is provided with a particulate filter disposed in an exhaust passage of an internal combustion engine and capturing particulate matter in exhaust gas discharged from the internal combustion engine. The particulate filter is provided with a wall-flow part 20 having an inlet-side cell 22 that is open only at an end on an exhaust gas inflow side, an outlet-side cell 24 that is adjacent to this inlet-side cell 22 and is open only at an end on an exhaust gas outflow side, and a porous wall 26 that partitions the inlet-side cell 22 from the outlet-side cell 24, and is also provided with a straight-flow part 30 having a through cell 32 that penetrates the filter in an axial direction thereof and is open at the end on the exhaust gas inflow side as well as the end on the exhaust gas outflow side.

摘要： A particulate filter provided in the exhaust gas purification device according to the present invention includes: a wall-flow part 20 having an inlet-side cell 22 that is open only at an end on an exhaust gas inflow side, an outlet-side cell 24 that is adjacent to this inlet-side cell 22 and is open only at an end on an exhaust gas outflow side, and a porous wall 26 that partitions the inlet-side cell 22 from the outlet-side cell 24; and a straight-flow part 30 having a through cell 32 that penetrates the filter in an axial direction thereof and is open at the end on the exhaust gas inflow side as well as the end on the exhaust gas outflow side. Here, in a cross section of the filter 100 orthogonal to its axial direction, cross-sectional areas of the inlet-side cell 22 and the outlet-side cell 24 present in an outer peripheral region of the cross section are larger than cross-sectional areas of the inlet-side cells 22 and the outlet-side cell 24 present in a central region of the cross section.
摘要翻译：本发明的废气净化装置所具备的微粒过滤器具备：壁流部20，其具有仅在废气流入侧的端部开口的入口侧单元22;出口侧单元24 与该入口侧电池22相邻且仅在排气流出侧的端部开口的多孔壁26;将入口侧电池22与出口侧电池24分隔的多孔壁26; 以及具有贯通孔32的直流部30，贯通孔32在轴向上贯通过滤器，在排气流入侧的端部以及排气流出侧的端部开口。在此，在与轴方向正交的过滤器100的截面中，存在于截面的外周区域的入口侧单元22和出口侧单元24的截面积大于截面积入口侧单元22和出口侧单元24的区域存在于横截面的中心区域中。
