Because of major interest in the combustion process for the presentation of a numerical simulation model, the gas exchange process is simply assumed to be of the idealized indicator diagram. As the fuel, n-octane and as the components of the burned gas, eleven species, CO, CO_2, H, H_2, H_2O, N, N_2, NO, O, O_2 and OH are considered to be in chemical equilibrium except for NO whose formation is predicted by Zeldovich mechanism. Stepwise solutions of the time- and space-dependent mass- and energy-conservation equations together with associated gasdynamic and chemical equations yield the time histories of thermodynamic properties and chemical compositions throughout the engine cycle under various operation conditions of the compression-ratio, the boost pressure (charging efficiency), the engine speed, the ignition timing, the air-fuel ratio (equivalence ratio), the burning velocity etc. The results demonstrate definitely major effects of these operating parameters on the cycle performance and provide comprehensibly the details of the combustion process and the NO formation during the engine operation, although the used assumptions still remain to be further investigated.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124446000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"item_9_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八田, 桂三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐野, 妙子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HATTA, Keizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SANO, Taeko","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":"2020-01-23"}],"displaytype":"detail","filename":"SA0124446.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124446.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31533/files/SA0124446.pdf"},"version_id":"4a4d40d4-ea1a-4efc-9d1f-81563bd71970"}]},"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":"火花点火機関の燃焼および性能に関する数値実験的研究 : 第1報4サイクル機関","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"火花点火機関の燃焼および性能に関する数値実験的研究 : 第1報4サイクル機関"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31533","relation_version_is_last":true,"title":["火花点火機関の燃焼および性能に関する数値実験的研究 : 第1報4サイクル機関"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:57:21.190284+00:00"}
