Title (EN) EXHAUST GAS PURIFYING CATALYST FOR 2-STROKE GENERAL-PURPOSE ENGINES
(FR) CATALYSEUR DE PURIFICATION DE GAZ D’ÉCHAPPEMENT POUR MOTEURS À USAGE GÉNÉRAL À 2 TEMPS
(JA) 2ストローク汎用エンジン用排ガス浄化触媒
Abstract:
(EN) An exhaust gas purifying catalyst for 2-stroke general-purpose engines, which is characterized in that: the exhaust gas purifying catalyst comprises a base and a coat layer on the base; the coat layer contains noble metals and metal oxides; the noble metals include palladium and one or more elements selected from among platinum and rhodium; the zirconia content in the coat layer is 0.07 mole or less per 100 g of the metal oxides contained in the coat layer; and the total content of one or more metal oxides selected from among lanthana and alkaline earth metal oxides in the coat layer is 0.05 mole or more per 100 g of the metal oxides contained in the coat layer.
(FR) L'invention concerne un catalyseur de purification de gaz d'échappement pour moteurs à usage général à 2 temps, qui est caractérisé en ce que : le catalyseur de purification de gaz d'échappement comprend une base et une couche de revêtement sur la base ; la couche de revêtement contient des métaux nobles et des oxydes de métal ; les métaux nobles comprennent du palladium et un ou plusieurs éléments choisis parmi le platine et le rhodium ; la teneur en zircone dans la couche de revêtement est inférieure ou égale à 0,07 mole pour 100 g des oxydes de métal contenus dans la couche de revêtement ; et la teneur totale d'un ou plusieurs oxydes de métal choisis parmi des oxydes de métal alcalino-terreux ou de lanthane dans la couche de revêtement est supérieure ou égale à 0,05 mole pour 100 g des oxydes de métal contenus dans la couche de revêtement.
(JA) 基体と、該基体上のコート層と、を有し、前記コート層が貴金属及び金属酸化物を含み、前記貴金属が、パラジウムと、白金及びロジウムから選択される1種以上と、を含み、前記コート層のジルコニアの含有量が、該コート層に含まれる金属酸化物100g当たり0.07モル以下であり、そして前記コート層のランタナ及びアルカリ土類金属酸化物から選択される1種以上の金属酸化物の合計含有量が、該コート層に含まれる金属酸化物100g当たり0.05モル以上であることを特徴とする、2ストローク汎用エンジン用排ガス浄化触媒。
