    摘要： Provided is a particulate filter in which a PM collection rate is stably increased. The particulate filter according to the present invention includes a substrate 10 having a wall flow structure having a porous partition wall 16 that partitions an inlet cell and an outlet cell, and a wash coat layer held on surfaces of internal pores of the partition wall. In addition, average filling rates A, B, and C of the wash coat layer measured for each predetermined pore diameter range in the internal pores satisfy specific relationships. Further, the wash coat layer is formed in a region that occupies 50% or more of a thickness of the partition wall, and an amount of a noble metal catalyst carried by the wash coat layer is 0 g/L or more but 0.2 g/L or less.

    摘要： The technology disclosed herein provides a particulate filter that can appropriately avoid PM from passing toward the outlet cell and can exhibit an excellent PM capturing performance. The particulate filter 1 disclosed herein includes: an outercoat layer 20 provided on an inlet surface 16a of a partition 16 of a base material 10. The outercoat layer 20 at least includes: a lower layer 22 provided on the inlet surface 16a of the partition 16; and an upper layer 24 provided to cover the lower layer 22. The mean particle diameter of granules contained in the upper layer 24 is higher than the mean particle diameter of granules contained in the lower layer. The mean particle diameter of the granules in the lower layer 22 is from 0.4 µm to 2.0 µm inclusive, and the mean particle diameter of the granules in the upper layer 24 is from 2.0 µm to 7.0 µm inclusive. With such a configuration, PM can be captured in an inlet cell 12, thereby suitably avoiding PM from passing toward an outlet cell 14 and exhibiting an excellent PM capturing performance.

    摘要： A wall-flow exhaust gas-purifying catalyst in which a pressure loss caused by accumulation of PM is small is provided. An exhaust gas-purifying catalyst (1) of the present invention includes a catalyst-coated filter (2). The catalyst-coated filter (2) includes a filter substrate (21) and a catalyst layer (22) on a pore wall of the filter substrate (21). The exhaust gas-purifying catalyst (1) has a first end, a second end, a porous wall (W), a first cell, and a second cell. The first cell is closed at the second end, the second cell is closed at the first end, and the first cell and the second cell are adjacent to each other with the porous wall (W) interposed therebetween. At a surface of the porous wall (W) on the first cell side, a proportion S S /S of a total area Ss of pores having an opening diameter of less than 40 um in a total area S of all pores is 65% or more.

    摘要： A particulate filter disclosed here includes a base material 10 having a wall-flow structure including porous partition walls 16 partitioning inlet cells 12 and outlet cells 14, and wash-coating layers 20 held inside the partition walls 16. The wash-coating layers 20 include inlet layers 22 each formed from a vicinity of an end portion at an exhaust gas inflow side XI to have a predetermined length and a predetermined thickness and outlet layers 24 each formed from a vicinity of an end portion at an exhaust gas outflow side X2 to have a predetermined length and a predetermined thickness. The inlet layers 22 and the outlet layers 24 partially overlap with each other. The inlet layers 22 of the particulate filter contain substantially no noble metal catalyst, and the outlet layers 24 contain a noble metal catalyst. Accordingly, PM collection performance can be easily enhanced in an inlet region, and high gas distributability (pressure loss suppression performance) can be maintained in the outlet region. Accordingly, it is possible to provide a particulate filter capable of achieving high levels of PM collection performance and pressure loss suppression performance.
