Title (EN) EXHAUST GAS PURIFICATION DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE PURIFICATION DES GAZ D'ÉCHAPPEMENT POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の排ガス浄化装置
Abstract:
(EN) An exhaust gas purification device 100 for an internal combustion engine 1 according to the present invention is provided with a plurality of catalysts 10 which are provided in series in an exhaust pipe 2. Phosphorus-containing engine oil is circulated in the internal combustion engine. The catalyst 10a positioned furthest upstream among the plurality of catalysts is provided with: an upstream section 53 which extends a prescribed distance L1 downstream from an upstream end 51; and a downstream section 54 positioned further downstream than the upstream section. The upstream section and the downstream section include a catalytic metal. The upstream section supports a smaller amount of the catalytic metal per unit length than the downstream section.
(FR) La présente invention concerne un dispositif de purification des gaz d'échappement (100) pour un moteur à combustion interne (1), ledit dispositif comprenant une pluralité de catalyseurs (10) qui sont disposés en série dans un tuyau d'échappement (2). De l'huile moteur contenant du phosphore est mise en circulation dans le moteur à combustion interne. Le catalyseur (10a) positionné le plus en amont parmi la pluralité de catalyseurs comporte : une section amont (53) qui s'étend sur une distance prédéterminée (L1) en aval d'une extrémité amont (51) ; et une section aval (54) positionnée plus en aval que la section amont. La section amont et la section aval comprennent un métal catalytique. La section amont supporte une plus petite quantité de métal catalytique par longueur unitaire que la section aval.
(JA) 本開示によれば、排気管2に直列に設けられた複数の触媒10を有する内燃機関1の排ガス浄化装置100がであって、内燃機関には、リンを含むエンジンオイルが循環され、複数の触媒のうち最上流側に位置する触媒10aは、上流端51から所定距離L1下流側までの上流側部分53と、上流側部分より下流側に位置する下流側部分54とを有し、上流側部分と下流側部分は触媒金属を含み、上流側部分は下流側部分より、単位長さ当たりにおける触媒金属の担持量が少ない。
