テイキユレート捕集装置。[Claims for Utility Model Registration] A filter cell having a partition wall of a porous ceramic structure is formed to collect particulate matter, the collected particulate matter is ignited by an external heating means, and the combustion is propagated to regenerate the filter cell. In the exhaust gas purification device for a diesel engine having this structure, the partition wall of the filter cell from a predetermined part downstream of the ignition part to the downstream end is coated with a ceramic coating having better thermal conductivity than the constituent material of the partition wall. A diesel engine particulate collection device characterized by being coated.
