EXHAUST GAS PURIFYING APPARATUS, PARTICULATE FILTER AND MANUFACTURING METHOD THEREOF

摘要

This invention relates to an exhaust gas purifying ap aratus having a particulate filter for collecting particulates in exhaust gas. This particulate filter (22) contains partition walls defining paths (50, 51) in wich 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. Alcording to this invention, the end portion of the particulate filter (22) has a higher strength than the predetermined bonding strength.
