摘　　要：在定容燃烧弹中进行了高喷射压力条件下加氢生物柴油与普通柴油的喷油特性试验,利用高速摄像机对2种燃油的喷油形态、喷雾锥角及油束贯穿距离等进行了拍摄,利用相关仿真软件分析及研究了喷油压力、缸内气体压力及温度等参数对加氢生物柴油油束贯穿距离的影响规律。研究结果表明:喷油压力提高,加氢生物柴油的油束贯穿距离增大;缸内气体压力升高,加氢生物柴油的油束贯穿距离增大;缸内气体温度升高,加氢生物柴油的油束贯穿距离先增大后减小。In the fixed-volume incendiary bomb,the fuel injection characteristics of hydrogenated biodiesel and ordinary diesel under high injection pressure conditions were tested,and the fuel injection form,spray cone angle and oil beam penetration distance of the two fuels were photographed by high-speed cameras,and the influence of fuel injection pressure,cylinder gas pressure and temperature on the penetration distance of hydrogenated biodiesel oil beam was analyzed and studied by using relevant simulation software.The results show that the fuel injection pressure increases and the oil beam penetration distance of hydrogenated biodiesel increases.The gas pressure in the cylinder increases,and the oil beam penetration distance of hydrogenated biodiesel increases.The gas temperature in the cylinder increases,and the oil beam penetration distance of hydrogenated biodiesel first increases and then decreases.
