A porous honeycomb filter made from a material containing cordierite, of which pore distribution is controlled, as the primary crystalline phase. The pore distribution is such that the volume of a pore with a diameter of below 10 µm is 15% or less of the total pore volume, the volume of a pore with a diameter of 10 to 50 µm is 75% or more of the total pore volume, and the volume of a pore with a diameter of above 50 µm is 10% or less of the total pore volume. This porous honeycomb filter has a high collection efficiency for fine particles (particulates), or the like, and can prevent increase in pressure loss due to the plugging of pores, and particularly can exploit the characteristics thereof for diesel engines that use recent high-pressure fuel injection, common rails, etc.
L'invention concerne un filtre alvéolaire poreux présentant une répartition de taille de pores commandée, ledit filtre comportant un matériau contenant de la cordiérite en tant que phase cristalline primaire. Le filtre selon l'invention est caractérisé en ce que le volume de pores de diamètre inférieur à 10 mu m est 15 % ou moins du volume total de pores, le volume de pores de diamètre compris entre 10 et 50 mu m est 75 % ou plus du volume total de pores, et le volume de pores de diamètre supérieur à 50 mu m est 10 % ou moins du volume total de pores. Ledit filtre alvéolaire poreux permet une meilleure capture d'agents contaminants particulaires et similaires, et permet également d'éviter l'augmentation de la perte de pression due au colmatage des pores, notamment lorsque ledit filtre est employé dans un moteur diesel de conception récente faisant intervenir l'injection de carburant haute pression, de type à rampe commune et similaires.
