摘要： An exhaust gas purifying system for a gasoline engine with high NH3 purifying performance after duration is provided. The exhaust gas purifying system for a gasoline engine disclosed herein is configured to be disposed in an exhaust path of the gasoline engine. The exhaust gas purifying system includes an upstream catalyst converter including a first catalyst body and a downstream catalyst converter including a second catalyst body. The first catalyst body contains a catalyst precious metal. The second catalyst body has a structure in which an NH3 adsorption layer and a catalyst layer are stacked on a base material. The NH3 adsorption layer of the second catalyst body contains a zeolite as an NH3 adsorber. The catalyst layer of the second catalyst body contains a catalyst precious metal and an OSC material.

摘要： The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end and a downstream end. The first catalyst layer contains first catalyst particles and lies on the substrate across a first region extending between the upstream end and a first position. The first position is at a first distance from the upstream end toward the downstream end. The second catalyst layer contains second catalyst particles and lies on the first catalyst layer across the first region. The second catalyst layer is provided with pores. Pore connectivity of the second catalyst layer is 5% to 35%. A mean value of areas of the pores of the second catalyst layer in a cross-sectional backscattered electron image of the second catalyst layer may be 0.7 µm2 to 9.0 µm2.
