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 4):
The exhaust gas purification device according to  claim 1 , wherein the upstream catalyst layer is formed so as not to overlap the downstream catalyst layer, in a length direction of the substrate.
