| Abstract(J) | ディーゼル機関は，火花点火機関と比べ，熱効率が高く，CO2排出量が少ないといったメリットがある一方，低温時において，始動性が悪いことや青白煙の発生などのデメリットがある．これらは燃料噴霧の良否に大きく依存するため，そのディーゼル噴霧の特性を把握する必要がある．そこで，低温条件下での燃料噴射条件と雰囲気圧力の変化が，燃料噴射の時間的特性（噴射特性）に及ぼす影響について調査した． Translation |
| Abstract(E) | In order to understand the characteristics of diesel spray under low temperature conditions, it is important to understand the temporal variation of fuel injection rate. In this study, the effects of fuel injection conditions and atmospheric pressure on fuel injection rate under low temperature conditions were investigated using momentum flux. Obtained results show that the start of injection delays and the rate of fuel injection decreases with decreasing fuel temperature due to increasing the fuel viscosity. In the case of a short injection duration, the end of injection becomes faster as the fuel temperature decreases. |
