A steam turbine which is used for the solar thermal power system uses a lot of water. The Sun Belt zone which has high direct solar radiation is suitable for the solar thermal power system. However, these areas correspond with desert zone and water shortage water zone. Accordingly, it is needed to develop an electricity generating system which does not use the water. In order to solve the problem, the authors develop a generator with a reciprocating engine driven by only compressed air. This engine was remodeled from four strokes to two strokes. Valve timing was decided by considering ideal p-V diagram. Intake valve opening period is from TDC to 100 deg. and exhaust valve opening period is from BDC to TDC. During the valve closing period, internal gas expands adiabatically. The engine takes compressed air from a compressor through a surge tank. The maximum supply pressure was 0.7MPa. In the experiment, temperature of intake and exhaust port, cylinder internal pressure was measured. In order to evaluate the performance of the engine, indicated work and various coefficients was calculated. As a result, it is found that the maximum efficiency was approximately 6.6 % under 443 W of load condition. In comparison with the theoretical efficiency, it is very low. Therefore, further development should be done.","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":"下別府, 陽平","creatorNameLang":"ja"},{"creatorName":"シモベップ, ヨウヘイ","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":"河村, 隆介","creatorNameLang":"ja"},{"creatorName":"カワムラ, リュウスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Shimobeppu, Yohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawamura, Ryuusuke","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":"engineering44_179-182.pdf","filesize":[{"value":"541.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://miyazaki-u.repo.nii.ac.jp/record/4733/files/engineering44_179-182.pdf"},"version_id":"97ba0a92-2b9b-4dad-b8f5-d8461e396945"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Solar power generation, Reciprocating engine, Beam-Down Solar Concentrator","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":"ビームダウン式太陽集光装置のための発電用エンジンの研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ビームダウン式太陽集光装置のための発電用エンジンの研究","subitem_title_language":"ja"},{"subitem_title":"Study on Power Generation Engine for Beam-Down Solar Concentrator","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","325"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-06-21"},"publish_date":"2020-06-21","publish_status":"0","recid":"4733","relation_version_is_last":true,"title":["ビームダウン式太陽集光装置のための発電用エンジンの研究"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-09-02T13:01:54.629707+00:00"}
