Abstract: The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end and a downstream end. The first catalyst layer contains first catalyst particles and lies on the substrate across a first region extending between the upstream end and a first position. The first position is at a first distance from the upstream end toward the downstream end. The second catalyst layer contains second catalyst particles and lies on the first catalyst layer across the first region. The second catalyst layer is provided with pores. Pore connectivity of the second catalyst layer is 5% to 35%. A mean value of areas of the pores of the second catalyst layer in a cross-sectional backscattered electron image of the second catalyst layer may be 0.7 µm2 to 9.0 µm2.

Abstract: A catalytic wall-flow filter for exhaust gas from a gasoline engine is disclosed. The catalytic wall-flow filter comprises a wall-flow filter substrate having porous walls and a first face and a second face defining a longitudinal direction therebetween and first and second pluralities of channels extending in the longitudinal direction. The first plurality of channels is open at the first face and closed at the second face, and the second plurality of channels is open at the second face and closed at the first face. The filter comprises a first TWC coating comprising a first PGM composition, a first oxygen storage capacity (OSC) material, and a first inorganic support; and a second TWC coating comprising a second PGM composition, a second OSC material, and a second inorganic support.
