  • Patent number: 11266982
    Abstract: A substrate (11) of an exhaust gas purification catalyst (10) includes inflow-side cells (21), outflow-side cells (22), and porous partition walls (23), each porous partition wall separating the cells (21, 22) from each other. A first catalyst portions (14) is provided at least on a portion of a side of the partition wall (23) that faces the inflow-side cell (21), the portion being located on an upstream side in an exhaust gas flow direction, and a second catalyst portion (15) is provided at least on a portion of a side of the partition wall that faces the outflow-side cell, the portion being located on a downstream side in the exhaust gas flow direction.

  • Patent number: 11097260
    Abstract: A substrate (11) includes an inflow-side cell (21), an outflow-side cell (22), and a porous, gas-permeable partition wall (23) that separates the inflow-side cell (21) and the outflow-side cell (22) from each other, and also includes a first catalyst portion (14) that is provided on a side of the partition wall (23) that faces the inflow-side cell (21) at least at a portion in upstream side in an exhaust gas flow direction, and a second catalyst portion (15) that is provided on a side of the partition wall that faces the outflow-side cell at least at a portion in downstream side.
