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 1):
An exhaust gas purification device that is disposed in an exhaust passage of an internal combustion engine and that purifies exhaust gas emitted by the internal combustion engine, the device comprising:\n a substrate of wall-flow structure having an inlet cell in which only an exhaust gas inflow end section is open, an outlet cell which is adjacent to the inlet cell and in which only an exhaust gas outflow end section is open, and a porous partition wall that partitions the inlet cell and the outlet cell from each other; an upstream catalyst layer provided inside the partition wall and disposed in an upstream portion of the substrate in a direction of exhaust gas flow, the upstream portion including the exhaust gas inflow end section; and a downstream catalyst layer provided inside the partition wall and disposed in a downstream portion of the substrate in the direction of exhaust gas flow, the downstream portion including the exhaust gas outflow end section, wherein the downstream catalyst layer contains a first carrier, and Rh supported on the first carrier; and the upstream catalyst layer contains a second carrier, and at least one of Pd and Pt supported on the second carrier.
