For sharp cut-off, there is a lower limit to oil speed in the injection pipe; or expressed differently, the pipe must not be too large compared with the nozzle. When the oil speed is lower than this limit, the pressure cannot be cut-off sharply, and the pressure-time curve takes the form of steps. These facts were ascertained by experiments. There is also an upper limit to oil speed for sharp cut-off, and if the oil speed exceeds this limit, the form of the pressure-time curve must also be steplike. In this case, however, experimen's show that the steps can be seen clearly only when the oil speed is very high, or the pipe is very small.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4147647000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, Tokyo Imperial University"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00387631","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中西, 不二夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 正治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北村, 菊男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKANISHI, Fujio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, Masaharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KITAMURA, Kikuo","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":"SA4147647.pdf","filesize":[{"value":"595.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4147647.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35479/files/SA4147647.pdf"},"version_id":"4824b321-7ed0-4ed6-bad7-24b457adf254"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"On the Effect of Pipe Bores on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Effect of Pipe Bores on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1993"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35479","relation_version_is_last":true,"title":["On the Effect of Pipe Bores on the Cut-off of Fuel Spray in Injection Systems with Open Nozzles."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:18:43.447694+00:00"}
