Exhaust gas purification filter |
| abstract |
An object of the present invention is to provide an exhaust gas purification filter capable of facilitating downsizing while improving the collection rate of particulate matter. An exhaust gas purification filter has a honeycomb structure and an upstream plug portion. The plurality of cell holes 5 include an inflow cell hole 51 and an outflow cell hole 52. The honeycomb structure 2 has a center side region 23 and an outer peripheral side region 24. In each of the center side region 23 and the outer peripheral side region 24, the flow passage cross-sectional areas Sc2 and So2 of the outflow cell hole 52 are larger than the flow passage cross-sectional areas Sc1 and So1 of the inflow cell hole 51. The channel cross-sectional area Sc1 is smaller than the channel cross-sectional area So1. The channel cross-sectional area ratio Rc, which is the ratio of Sc1 to Sc2, is smaller than the channel cross-sectional area ratio Ro, which is the ratio of So1 to So2. In both the first direction X and the second direction Y, the inflow cell holes 51 and the outflow cell holes 52 are alternately arranged, and the cell wall 4 in the central region 23 is more than the cell wall 4 in the outer peripheral region 24. Also thick. [Selection] Figure 4 |
