Exhaust gas purifying apparatus, particulate filter and manufacturing method thereof

摘要

This invention relates to an exhaust gas purifying apparatus having a particulate filter for collecting particulates in exhaust gas. This particulate filter ( 22 ) contains partition walls defining paths ( 50, 51 ) in which exhaust gas flows. This partition wall is formed of porous material. This particulate filter ( 22 ) is created by gathering tips of the partition walls and then baking with the adjacent partition walls being in contact with each other. The adjacent partition walls are bonded together at a predetermined bonding strength if the partition walls are baked such that they are in contact. According to this invention, the end portion of the particulate filter ( 22 ) has a higher strength than the predetermined bonding strength.
