| Abstract(J) | 本研究では燃料の動粘度，表面張力および密度に注目し，それぞれの物性値のみが主に異なる燃料を製作した．60MPaに加圧した燃料を噴孔径0.133mmの10噴孔インジェクタから大気圧中に噴射し，燃料噴霧を高速度カメラで撮影した．動粘度が低い場合および表面張力が低い場合は噴霧幅が広い．密度が高い場合は噴霧先端到達距離が短い． Translation |
| Abstract(E) | The kinematic viscosity, surface tension, and density of the fuel were focused in this study, and test fuels were prepared in which only these physical properties differed. The test fuel, pressurized to 60 MPa, was injected into the atmosphere through a 10-hole injector with a nozzle diameter of 0.133 mm. The fuel spray was observed using a high-speed camera. The spray width was wider when the kinematic viscosity was low or the surface tension was low. The spray penetration was shorter when the density was high. |
