Title (EN) LOW WASHCOAT LOADING SINGLE LAYER CATALYST FOR GASOLINE EXHAUST GAS CLEANING APPLICATIONS
(FR) CATALYSEUR À COUCHE UNIQUE À FAIBLE CHARGE D'IMPRÉGNATION POUR DES APPLICATIONS DE NETTOYAGE DE GAZ D'ÉCHAPPEMENT D'ESSENCE
Abstract:
(EN) A three-way catalyst article, and its use in an exhaust system for internal combustion engines, is disclosed. The catalyst article for treating exhaust gas comprising: a substrate; and a single catalyst layer deposited directly on the substrate; wherein the single catalyst layer comprises a first platinum group metal (PGM) component, an oxygen storage component (OSC) material, and an inorganic oxide; and wherein the single catalyst layer has a total washcoat loading of less than 0.15 g/cm3 (2.4 g/in3).
(FR) La présente invention concerne un article de catalyseur à trois voies et ses utilisations dans un système d'échappement pour moteurs à combustion interne. L'article de catalyseur pour le traitement de gaz d'échappement comprend : un substrat; et une seule couche de catalyseur déposée directement sur le substrat; la couche de catalyseur unique comprenant un premier composant de métal du groupe du platine (PGM), un matériau de composant de stockage d'oxygène (OSC) et un oxyde inorganique; et la couche de catalyseur unique ayant une charge d'imprégnation totale inférieure à 0.15 g/cm3 (2.4 g/in3).
