EXHAUST PURIFYING FILTER
摘要:
Provided is an exhaust purifying filter having high catalyst purification performance and particulate matter capturing performance while reducing pressure loss. A GPF includes a filter substrate in which a plurality of cells extending from an inflow-side end surface to an outflow-side end surface are partitioned and formed by a porous partition wall and an inflow-side cell in which an opening in the outflow-side end surface is sealed and an outflow-side cell in which an opening in the inflow-side end surface is sealed are alternately disposed; and a TWC which is carried on the partition wall, wherein a difference between a total volume of pores having pore diameters within a range of 0.1 μm to 10.7 μm in pore distribution of the GPF and a total volume of pores having pore diameters within a range of 0.1 μm to 10.7 μm in pore distribution of the filter substrate is 0.015 ml/g˜0.06 ml/g.
