Abstract[English]
A catalytic wall-flow filter for exhaust gas from a gasoline engine is disclosed. The catalytic wall-flow filter comprises a wall-flow filter substrate, a first TWC coating in the first plurality of channels, and a second TWC coating in the second plurality of channels. The first TWC coating comprises palladium, rhodium, a first oxygen storage capacity (OSC) material, and a first inorganic support. The second TWC coating comprises platinum, rhodium, a second OSC material, and a second inorganic support.[French]
Un filtre à effet wall-flow catalytique pour gaz d'échappement provenant d'un moteur à essence est divulgué. Le filtre à effet wall-flow catalytique comprend un substrat de filtre à effet wall-flow, un premier revêtement de catalyseur trifonctionnel (TWC, « three-way catalyst ») dans la première pluralité de canaux et un second revêtement de TWC dans la seconde pluralité de canaux. Le premier revêtement de TWC comprend du palladium, du rhodium, un premier matériau de capacité de stockage d'oxygène (OSC) et un premier support inorganique. Le second revêtement TWC comprend du platine, du rhodium, un second matériau OSC et un second support inorganique.
