ガソリンエンジンにおける燃焼室内熱伝達の計測(空燃比の影響の検討) Measurement of Heat Transfer to Combustion Chamber of Gasoline Engine (Examination of Infuluence of Air-Fuel Ratio) ガソリン エンジン ニ オケル ネンショウシツナイ ネツデンタツ ノ ケイソク (クウネンヒ ノ エイキョウ ノ ケントウ) 90180489 長瀬, 慶紀 ナガセ, ヨシノリ Nagase, Yoshinori 長瀬 ナガセ Nagase 慶紀 ヨシノリ Yoshinori 宮崎大学 University of Miyazaki 亀園, 淳二 カメゾノ, ジュンジ 田坂, 英紀 タサカ, ヒデノリ Tasaka, Hidenori Kamezono, Junzi Gas flow, Heat transfer coefficient, Air-fuel ratio, Heat flux probe Abstract As for an internal combustion engine, making to highly effective is requested because of the improvement of environmental problems. For the purpose, the gas flow in the cylinder is introduced for the improvement of the rate of burning. However, to promote the heat transfer between the gas in the cylinder and the combustion chamber wall by introducing the gas flow, it does not necessarily connect with making to highly effective. In this research, gas flow measurements and heat flux measurements are carried out by changing swirl strength and air-fuel ratio. The relation between gas flow and heat transfer coefficient in air-fuel ratio change is clarified. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2004-10 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/333 https://miyazaki-u.repo.nii.ac.jp/records/2357 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 33 273 278 https://miyazaki-u.repo.nii.ac.jp/record/2357/files/KJ00002428254.pdf application/pdf 522.0 kB 2020-06-21
