JP JP2002219319A
SUBJECT OF THE INVENTION
Collection efficiencies, such as microparticles|fine-particles (particulate), are high, and increase of the pressure loss by clogging of a pore can be prevented,
The porous honey-comb filter which can exhibit these characteristics corresponding to the diesel engine which employ|adopted high pressure fuel injection in recent years, a common-rail, etc. especially, and its manufacturing method are provided.
PROBLEM TO BE SOLVED
It is a porous honey-comb filter which consists of material which makes the cordurite which controlled pore distribution the main crystal phase.
Pore volume which exceeds 50 micrometers of pore diameters for pore distribution 15 % or less of the pore-volume:all pore volume of less than 10 micrometers of pore diameters, and 75% or more of the pore-volume:all pore volume of 10-50 micrometers of pore diameters: You may be 10 % or less of total pore volume.
