EXHAUST GAS PURIFICATION DEVICE

WIPO Patent Application WO/2024/106260

A1

The purpose of the present invention is to provide an exhaust gas purification device that can suppress increases in pressure loss.　This exhaust gas purification device is characterized by comprising a honeycomb substrate and an inflow-cell-side catalyst, and is characterized in that: the honeycomb substrate comprises a porous partition wall that defines a plurality of cells that extend from an inflow-side end surface to an outflow-side end surface; the plurality of cells include an inflow cell and an outflow cell that are adjacent, with the partition wall sandwiched therebetween; the inflow cell is open at an inflow-side end and sealed at an outflow-side end; the outflow cell is sealed at an inflow-side end and open at an outflow-side end; the inflow-cell-side catalyst is disposed at least on an inflow-cell-side partition wall surface in an inflow-cell-side catalyst region of the partition wall, or in an inflow-cell-side partition wall interior region; and, if a position 50% of the length of the inflow-cell-side catalyst region from an inflow-side end of the partition wall in a direction of extension is considered a reference position, the proportion of a region of the partition wall covered by the inflow-cell-side catalyst in plan view of the inflow-cell-side partition wall surface of the partition wall at the reference position is in the range 50%–95%.
