Title (EN) DIESEL PARTICULATE FILTER AND EXHAUST GAS PURIFICATION DEVICE
(FR) FILTRE À PARTICULES DIESEL, ET DISPOSITIF DE PURIFICATION DE GAZ D'ÉCHAPPEMENT
(JA) ディーゼルパティキュレートフィルタ及び排気ガス浄化装置
Abstract: front page image
(EN)Proposed is a novel DPF which can prevent PM from accumulating on the surface and interior of a filter substrate, and can suppress an increase in back pressure caused by exhaust gas. The DPF has a configuration in which an inorganic porous layer, which includes a metal oxide or a metal composite oxide and is provided with surface irregularities having a thickness of at least 50% of the thickness of the inorganic porous layer, is formed on part or all of the surface of the dividing wall on the side where exhaust gas flows in.
(FR)L'invention fournit un nouveau filtre à particules diesel (DPF) qui inhibe la rétention d'un matériau particulaire à la surface et dans la partie interne d'un matériau de base de filtre, et qui permet d'empêcher l'élévation d'une contre-pression sous l'effet d'un gaz d'échappement. Le filtre à particules diesel de l'invention présente une configuration selon laquelle une couche poreuse non organique comprenant un oxyde de métal ou un oxyde de métal composite, et équipée d'une partie irrégularité superficielle d'une épaisseur supérieure ou égale à 50% de la sienne, est formée sur une partie ou l'ensemble d'une paroi de cloisonnement côté introduction du gaz d'échappement.
(JA) フィルタ基材の表面及び内部にPMが滞留するのを防止して、排ガスによる背圧の上昇を抑制することができる、新たなDPFを提案する。 金属酸化物又は金属複合酸化物を含有し、且つ、無機多孔質層の厚さの50%以上の厚さを有する表面凹凸部を備えた無機多孔質層を、排気ガスが流入する側の前記隔壁の表面の一部又は全部に形成してなる構成を備えたDPFを提案する。
