The biogas composition ratio is changed by fermentation condition. Combustibility of biogas was researched about relation between gas flow and flame shape using constant volume combustion chamber. But combustion characteristics of biogas/air mixture have not been researched in spark ignition engine. The purposes of this study are making of engine experimental system and comparing combustion characteristics of biogas with propane. First of all, the authors designed and made intake system for biogas supply, spark ignition system and combustion pressure measurement system. To comparing each combustion characteristics, combustion pressure was measured under same ignition timing condition. In these experiments, concentrations of methane in biogas were 70, 60 and 50%. From the result of pressure measurement, combustion period of propane mixture was the shortest in all conditions. For biogas mixtures, combustion period decreased with increase of methane concentration. Maximum combustion pressure increased with decrease of combustion period. As results, it was found as follows. To investigate combustion characteristics of biogas/air mixture, engine experimental system was designed and constructed. From combustion pressure measurement, there is high correlation between combustion period and methane concentration of biogas. However, to discuss about indicated work, indicated mean effective pressure, indicated thermal efficiency and specific fuel consumption of each conditions, these should be compared under MBT conditions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","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":"森口, 剛士","creatorNameLang":"ja"},{"creatorName":"モリグチ, コウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Tomomatsu, Shigeki","creatorNameLang":"en"},{"creatorName":"友松, 重樹","creatorNameLang":"ja"},{"creatorName":"トモマツ, シゲキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"長瀬, 慶紀","creatorNameLang":"ja"},{"creatorName":"Nagase, Yoshinori","creatorNameLang":"en"},{"creatorName":"長瀬, 慶記","creatorNameLang":"ja"},{"creatorName":"ナガセ, ヨシノリ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{},{}],"givenNames":[{},{},{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Moriguchi, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"36engineering40_pp.211-216pdf.pdf","filesize":[{"value":"947.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"36engineering40_pp.211-216pdf.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2725/files/36engineering40_pp.211-216pdf.pdf"},"version_id":"2c1e3bab-c25c-41a6-bd2e-50076e76abee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Composition ratio of Biogas, S.I. engine, Combustion Pressure, Combustion characteristic","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"火花点火機関におけるバイオガス燃料の燃焼特性に関する研究 : エンジン実験装置製作と燃焼実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"火花点火機関におけるバイオガス燃料の燃焼特性に関する研究 : エンジン実験装置製作と燃焼実験","subitem_title_language":"ja"},{"subitem_title":"Study on combustion characteristics of biogas fuel using S.I. engine : making of S.I. engine experimental device and combustion experiments","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","321"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-11"},"publish_date":"2012-03-11","publish_status":"0","recid":"2725","relation_version_is_last":true,"title":["火花点火機関におけるバイオガス燃料の燃焼特性に関する研究 : エンジン実験装置製作と燃焼実験"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-09-02T13:01:59.324580+00:00"}
