摘要:
本文设计了高压LPG喷雾实验装置,使用高速CCD相机和光学纹影法分别拍摄了不同喷油压力下,直喷发动机用的相同喷孔径的旋流喷嘴和非旋流喷嘴的液态LPG自由喷雾过程。结果表明:随喷射压力的增加,液态LPG喷雾的贯穿距离增大,而喷雾锥角减小;液态LPG在喷出后会产生闪急沸腾现象,导致LPG的喷雾贯穿距离比汽油喷雾的贯穿距离小一些,而喷雾锥角则大于汽油喷雾锥角;相对于非旋流喷嘴来说,旋流喷嘴燃油雾化效果更好,加速了喷雾的蒸发,有利于混合气的形成。
Abstract:
A LPG spray test system is established by using a high speed CCD camera and schlieren technique, swirl injector and non-swirl injector of the same diameter are used to capture the images of instant sprays at the different injection pressure. Results show, with the increase of the injection pressure, the spray tip penetration increases while the spray angle decreases. The flashing boiling of LPG makes its spray tip penetration less than that of gasoline, while its spray angle is greater than that of gasoline. The swirl injector has promoted the atomization and evaporation of liquid phase LPG than the non-swirl injector, and hence will produce a more homogeneous air-fuel mixture.
