摘要： The invention relates to a honeycomb structure including a set of adjacent channels, each channel being in communication with upstream and downstream surfaces, respectively, via upstream and downstream openings, such that said set of channels forms cross-sectional upstream and downstream patterns on said upstream and downstream surfaces, respectively. According to the invention, at least one of the upstream and downstream surfaces has an error-proofing mark extending over fewer than 50 channels and making it impossible to completely stack any one of the upstream and downstream patterns onto the other, the outer perimeter of the upstream and/or downstream pattern being symmetrical or having an asymmetry that extends over fewer than 10 channels. The invention can be used in the filtration of particles contained it the exhaust gases of internal combustion engines, in particular diesel engines.

摘要： A honeycomb structure includes aluminum titanate, cell walls, and pore portions. The cell walls extend along a longitudinal direction of the honeycomb structure to define cells between the cell walls. The pore portions have an average pore diameter of about 10 μm to about 20 μm. A length of a longest pore portion among the pore portions in a binary image including substrate portions and the pore portions is about 8 times or less of the average pore diameter. The binary image is converted from a microscopic image of a cross section of the cell walls in parallel with the longitudinal direction. The length is measured along a line drawn in a direction perpendicular to a thickness direction of the cell walls.
