Moreover, the volumetric flow rate was increased about 2.5 times at the same injection pressure. Although the spray tip penetration of the multi-hole nozzle is short, the spread of the spray is considerably large about 3 times as large as the previous single hole atomization enhancement nozzle, high-dispersion spray was obtained. Furthermore, the injector, which was designed for high-viscous liquid based on the atomization enhancement nozzle, the spread of the spray becomes large significantly and the droplet diameter becomes small, the excellent spray was obtained independent of kinematic viscosity.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究（C）研究期間：2007～2009課題番号：19560217研究分野：工学科研費の分科・細目：機械工学・熱工学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://rns.nii.ac.jp/nr/1000070298933"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"TAMAKI, NOBUSHIGE"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学・工学部・准教授"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"玉木,  伸茂"},{"creatorName":"タマキ, ノブシゲ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3344","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70298933","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_19560217seika.pdf","filesize":[{"value":"897.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_19560217seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3067/files/KAKEN_19560217seika.pdf"},"version_id":"a6b0c581-e7ca-4d93-aaed-de501bb304e2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ディーゼル機関","subitem_subject_scheme":"Other"},{"subitem_subject":"燃料噴射ノズル","subitem_subject_scheme":"Other"},{"subitem_subject":"噴霧特性","subitem_subject_scheme":"Other"},{"subitem_subject":"キャビテーション","subitem_subject_scheme":"Other"},{"subitem_subject":"燃焼特性","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"省エネ型・高効率内燃機関用噴射ノズルの実用開発と燃焼特性の改善","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"省エネ型・高効率内燃機関用噴射ノズルの実用開発と燃焼特性の改善"}]},"item_type_id":"8","owner":"3","path":["2699","2700"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-06"},"publish_date":"2010-07-06","publish_status":"0","recid":"3067","relation_version_is_last":true,"title":["省エネ型・高効率内燃機関用噴射ノズルの実用開発と燃焼特性の改善"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:47:44.121288+00:00"}
