ABSTRACT:
There is provided a particulate filter for trapping particulates contained in an exhaust gas discharged from a combustion chamber of an engine, comprising a plurality of exhaust gas flow passages each formed by three porous partitions extending substantially parallel with each other, each of the exhaust gas flow passages having a triangular cross section, wherein the partitions defining one of the adjacent exhaust gas flow passages are deformed at one end area of the filter so that the partitions at one end area of the filter approach each other toward one of the ends of the filter, the deformed portions of the partitions are connected to each other at their ends, thereby an opening of one of the adjacent exhaust gas flow passages is at least partially closed, the partitions defining the other exhaust gas flow passage are deformed at the other end area of the filter so that the partitions at the other end area of the filter approach each other toward the other end of the filter, and the deformed portions of the partitions are connected to each other at their ends, thereby an opening of the other exhaust gas flow passage is at least partially closed.
