| 摘 要： | 应用高速摄影系统与高压共轨系统,在高压定容器内研究了生物柴油的喷雾特性,并与柴油进行了对比。结果表明,生物柴油油束形态比柴油细且长,喷雾贯穿距离比柴油大,喷雾锥角比柴油小;高的运动黏度与表面张力导致生物柴油雾化性能比柴油差。随着喷油压力的升高,生物柴油喷雾贯穿距离变长,喷雾锥角增大;随着背压的升高,生物柴油喷雾贯穿距离...

| Abstract: | High speed photography system was used to investigate the spray behavior of biodiesel and diesel in a diesel engine common rail system.It is found that compared to diesel,biodiesel exhibits longer spray tip penetration and smaller spray cone angle.Higher viscosity and surface tension of biodiesel lead to bad atomization behavior than that of diesel.When the injection pressure increases, the spray tip penetration becomes longer and the spray cone angle becomes larger.When the ambient pressure increases,the s... |
