ルタ。[Claims for Utility Model Registration] An inlet passage that opens at the upstream end of the exhaust gas and closes at the downstream end of the exhaust gas, an outlet passage that closes at the upstream end and opens at the downstream end, and the inlet passage and the outlet passage. and a porous wall located between the pipes, so that when collecting particulate matter, the exhaust gas flows from the inlet passage to the outlet passage, and when regenerating the filter for particulate incineration, the exhaust gas flows from the outlet passage to the inlet passage. What is claimed is: 1. A diesel exhaust particulate filter using a reverse flow regeneration method, characterized in that a heat generating means for igniting and burning particulate is provided at the closed end of the inlet passage.
