Abstract:
An exhaust gas purification device includes: a substrate of wall-flow structure having an inlet cell, an outlet cell and a porous partition wall; an upstream catalyst layer provided inside the partition wall and disposed in an upstream portion, including an exhaust gas inflow end section, of the substrate; and a downstream catalyst layer provided inside the partition wall and disposed in a downstream portion, including an exhaust gas outflow end section, of the substrate. The downstream catalyst layer contains a carrier, and Rh supported on the carrier. The upstream catalyst layer contains a carrier, and Pd and/or Pt supported on the carrier.

Claim (Index 5):
The exhaust gas purification device according to  claim 1 ,\n wherein in a thickness direction of the partition wall, the upstream catalyst layer is unevenly distributed within the partition wall, so as to be in contact with the inlet cell and not in contact with the outlet cell, and the downstream catalyst layer is unevenly distributed within the partition wall, so as to be in contact with the outlet cell and not in contact with the inlet cell.
