A small quartz spectrometer, a hydrogen discharge tube as light source and a quartz reaction chamber of diameter 33mm, length 300mm were employed. The temperature susceptibility of lag, the time required for the appearance of formaldehyde absorption caused by premixed fuel-air mixture enclosed in reaction chamber at given preflame temperature, is measured under atmospheric pressure. Assuming the reciprocals of lag are proportional to reaction rates of radical formation in preflame combustion, apparent activation energies of these reactions are calculated. It was found that these activation energies of fuels differ greatly according to their chemical structures, and they are in the following order : Benzene > Ethyl alcohol > n-Heptane > Toluene > Methyl alcohol > i-Octane, Acetone > i-Propylether Concerning to engine experiences, when running conditions of engine become severe, the better the performance, the smaller the activation energy of fuel is. Thus, i-propylether improves its octane rating at higher mixture temperature. Tetraethyllead may be a feeder of active radicals into the oxidation mixtures under this experimental conditions, and could serve to cut down the lag of preflame reaction. The direct connection of formaldehyde formation rate under these experimental conditions to antiknocking property is not reasonable.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2410128000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学理工学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0371-6090","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":"AN00162611","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大學理工學研究所"},{"subitem_text_value":"東京大學理工學研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY, UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY, UNIVERSITY OF TOKYO"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山崎, 毅六"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMAZAKI, Kiroku","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMADA, Minoru","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":"2020-01-24"}],"displaytype":"detail","filename":"SA2410128.pdf","filesize":[{"value":"960.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2410128.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34667/files/SA2410128.pdf"},"version_id":"b12d7f4b-3b08-42b1-b8b9-162fab31e23d"}]},"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":"前炎燃燒におけるフォルムアルデヒド生成のおくれ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"前炎燃燒におけるフォルムアルデヒド生成のおくれ"}]},"item_type_id":"9","owner":"1","path":["1890","1908"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34667","relation_version_is_last":true,"title":["前炎燃燒におけるフォルムアルデヒド生成のおくれ"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:37:20.441625+00:00"}
