中文摘要：

采用相位多普勒粒子分析仪，从索特平均直径、喷雾锥角和喷雾贯穿距等方面对生物柴油和0^#柴油的喷雾特性进行了对比研究。基于高速摄像技术，拍摄了几个典型时刻生物柴油和0^#柴油的喷雾图片。结果表明：在相同的喷射条件下，生物柴油的索特平均直径和喷雾贯穿距大于0^#柴油，而喷雾锥角小于0^#柴油。

英文摘要：

The spray characteristics of bio-diesel oil and 0^# diesel oil, such as Sauter mean diameter（SMD）, spray angle and spray penetration distance, was investigated by using phase doppler particle analyzer（PDPA）. Based on high-speed digital photography, several representative spray pictures of bio-diesel oil and 0^# diesel oil were taken. The results show that SMD and spray penetration distance of bio-diesel oil are greater than that of 0^# diesel oil, while spray angle of bio-diesel oil is smaller than that of 0^#diesel oil at the same injection condition.
