直線噴射式ディーゼル機関の燃焼性能に及ぼす燃料噴孔形状の影響 Effects of Fuel Injector Orifice Configuration on Combustion Performance of DI Diesel Engins Gakushi, Nobuhiko Takamoto, Yoshihisa 瘧師, 信彦 高本, 与志久 In this report, the effects of fuel injector orifice configuration on the combustion performance were studied experimentally, for a high super-charged middle speed.DJ diesel engine. 1) The concentration distribution of burnt gas in the longitudinal direction of cylinder was governed by the angle of collision of fuel jet on the surface of piston crown. 2) Most homogeneous distribution was obtained by directing the fuel jet to the surface of piston crown where the distribution of air in the combustion chamber is maximum. Under this condition, the speed of heat release and the conversion efficiency of effective heat for gas to the indicated work were largest. 3) Super-charging pressure caused no change to the concentration distribution of burnt gas in the cylinder. 1979-03-25 金沢大学工学部 = Faculty of Technology Kanazawa University 1979-03-25 2017-10-03 jpn departmental bulletin paper VoR https://doi.org/10.24517/00011714 http://hdl.handle.net/2297/25554 https://kanazawa-u.repo.nii.ac.jp/records/11727 10.24517/00011714 AN00044309 0022-832X 金沢大学工学部紀要 = Memoirs of the Faculty of Technology Kanazawa University 12 1 77 85 https://kanazawa-u.repo.nii.ac.jp/record/11727/files/AN00044309-12-1-77.pdf application/pdf 233.1 kB 2017-10-03
