Generally, if the wall thickness is thin, the soot in diesel exhaust gas may break through and leak the filter, because the depth filtration doesn’t work enough. However, most of filtration efficiency depends on surface filtration, because the soot cake forms on the surface of ceramic filter, and the soot cake takes part in highly performance of the filter. Therefore, the most important thing is how to make the soot cake rapidly. In this study, we pay attention to the surface roughness of ceramic filter. We observed the micro-porous structure of the filter based on SEM images. Also, we measured soot diameter and particle number concentration using different filters. Results show that, when too big open and too deep pore exist on the filter surface, the soot leakage occurs easily. In this case, it’s hard to make soot layer rapidly and the soot leaks during initial DPF usage. Once the soot layer is formed, the filtration efficiency becomes high, and small particulates called SPM are caught effectively. Thus, it is important to control surface roughness for making soot layer rapidly.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/19810"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "一般社団法人 日本機械学会", "subitem_publisher_language": "ja"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0387-5016", "subitem_source_identifier_type": "PISSN"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "常吉, 孝治", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "51972", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "高木, 修", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "51973", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "山本, 和弘", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "51974", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TSUNEYOSHI, Koji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "51975", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKAGI, Osamu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "51976", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMAMOTO, Kazuhiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "51977", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "87.pdf", "filesize": [{"value": "1.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1100000.0, "url": {"label": "87.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/17744/files/87.pdf"}, "version_id": "853b4c0e-225c-47d1-99d7-7706a22654b1"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Diesel Engine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Combustion Products", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Porous Media", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ceramics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Suraface roughness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "DPF", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "DPFの初期PM捕集性能に対する表面粗さの影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "DPFの初期PM捕集性能に対する表面粗さの影響", "subitem_title_language": "ja"}]}, "item_type_id": "10", "owner": "1", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/19810", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2014-04-22"}, "publish_date": "2014-04-22", "publish_status": "0", "recid": "17744", "relation": {}, "relation_version_is_last": true, "title": ["DPFの初期PM捕集性能に対する表面粗さの影響"], "weko_shared_id": -1}
