Fuel temperature and wall temperature are especially important parameters because they are closely related to the fuel film formed by spray impingement on the wall. The purpose of this study is to clarify the mixture and fuel film formation process with wall impingement spray under low temperature fuel and wall conditions. Construction of a spray experiment equipment that can simultaneously cool fuel temperature and wall temperature, and Total internal reflection laser induced fluorescence (TIR-LIF) method was applied to the fuel film formed by wall impingement spray. TIR-LIF method can measure fuel film thickness by fluorescence from fuel film during the spray injection without the influence of the spray droplet. In this paper, the fuel and wall temperatures were controlled from 293 K to 253 K to investigated film formation process during spray injection. In addition heat of evaporation considering heat capacity of fuel film was estimated."},{"@language":"ja","@value":"直噴ガソリンエンジンでは零度を下回る冷間始動時でのPM排出低減が重要性を増している．本研究では，低温環境下における壁面衝突噴霧により形成された燃料液膜に対して噴霧液滴の影響を受けずに計測できるTIR-LIF法を適用し燃料および壁面温度を同時冷却した際の衝突期間中を含めた液膜形成過程の結果を報告する．"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410294208468945665","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Adachi Akira"},{"@language":"ja","@value":"安達 晃"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"同志社大学大学院"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294208468945666","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Maekawa Fuma"},{"@language":"ja","@value":"前川 楓馬"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"同志社大学大学院"}]},{"@id":"https://cir.nii.ac.jp/crid/1030859912488459648","@type":"Researcher","personIdentifier":[{"@type":"ORCID","@value":"0000-0002-4396-5844"},{"@type":"NRID","@value":"9000409988191"},{"@type":"NRID","@value":"9000415348103"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/daimatsuda"}],"foaf:name":[{"@language":"en","@value":"Matsuda Dai"},{"@language":"ja","@value":"松田 大"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"同志社大学大学院"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294208468945664","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Matsumura Eriko"},{"@language":"ja","@value":"松村 恵理子"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"同志社大学"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294208468945668","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Senda Jiro"},{"@language":"ja","@value":"千田 二郎"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"同志社大学"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294208468945667","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Okuma Masahiro"},{"@language":"ja","@value":"大隈 正寛"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"株式会社デンソー"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294208468945669","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Saiki Yusuke"},{"@language":"ja","@value":"齋木 優佑"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"株式会社デンソー"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"02878321"},{"@type":"EISSN","@value":"18830811"}],"prism:publicationName":[{"@language":"en","@value":"Transactions of Society of Automotive Engineers of Japan"},{"@language":"ja","@value":"自動車技術会論文集"},{"@language":"en","@value":"JSAE Transactions"},{"@language":"en","@value":"Transactions of the Society of Automotive Engineers of Japan"},{"@language":"ja","@value":"自動車技術会論文集"}],"dc:publisher":[{"@language":"en","@value":"Society of Automotive Engineers of Japan"},{"@language":"ja","@value":"公益社団法人 自動車技術会"}],"prism:publicationDate":"2022","prism:volume":"53","prism:number":"6","prism:startingPage":"1192","prism:endingPage":"1197"},"availableAt":"2022","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Heat%20engine","dc:title":"Heat engine"},{"@id":"https://cir.nii.ac.jp/all?q=Spark%20ignition%20engine","dc:title":"Spark ignition engine"},{"@id":"https://cir.nii.ac.jp/all?q=Cold%20start","dc:title":"Cold start"},{"@id":"https://cir.nii.ac.jp/all?q=Fuel%20injection/fuel%20spray","dc:title":"Fuel injection/fuel spray"},{"@id":"https://cir.nii.ac.jp/all?q=Wall%20impingement%20spray","dc:title":"Wall impingement spray"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2009984978"}]}
