Patent number: 6773481Abstract: 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 &mgr;m is 15% or less of the total pore volume, the volume of a pore with a diameter of 10 to 50 &mgr;m is 75% or more of the total pore volume, and the volume of a pore with a diameter of above 50 &mgr;m 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.Type: GrantFiled: July 17, 2002Date of Patent: August 10, 2004Assignee: NGK Insulators, Ltd.Inventors: Yasushi Noguchi, Hideaki Nishi, Hiroyuki Suenobu
