Title (EN) PARTICLE FILTER INCLUDING A CATALYTIC PHASE
(FR) FILTRE A PARTICULES COMPRENANT UNE PHASE CATALYTIQUE
Abstract:
(EN) The invention relates to a particle filter for purifying exhaust fumes produced by an internal combustion engine including a filtering substrate made of porous ceramic and a catalytic phase, characterised in that the catalytic phase is made of yttria zirconia. The invention also relates to an exhaust line including such a particle filter.
(FR) L'invention concerne un filtre à particules pour l'épuration des gaz d'échappement produits par un moteur à combustion interne comprenant un substrat filtrant en céramique poreuse et une phase catalytique, caractérisé en ce que la phase catalytique est à base de zircone yttriée. L'invention a aussi pour objet une ligne d'échappement comprenant un tel filtre à particules.
