摘 要: | 采用实验手段,在5~65℃温度范围内,对柴油/汽油混合燃料的几种基本物性参数进行测量与研究。通过对不同掺混比(柴油体积分数分别为20%,40%,60%,80%)下混合燃料的密度、黏度、表面张力及稳定性等物理特性的测试与研究,总结了混合燃料密度、黏度及表面张力随温度及掺混比的变化规律,得到了具有较高精度的混合燃料的物性参数经验关系式,建立了较为完善的柴油/汽油混合燃料物性参数数据库。 |
关 键 词: | 内燃机工程;柴油/汽油;混合燃料;物理特性 |

Abstract: | Physical properties including density, viscosity, surface tension and the stability of the different contents of diesel-gasoline blend fuel parameters were measured and analyzed. The experiments were performed on the diesel-gasoline blend fuel with 4 different volume fractions of diesel (20%, 40%, 60%, and 80% respectively) at temperature from 5 to 65℃. Based on experimental data, the influence of temperature and diesel content on the blends properties was summarized and the formulas for the material parameters were determined. In addition, a database of the material parameters of the blends was established. |
