The microcosmic spray characteristics of diesel and biodiesel at constant pressure were studied by using Ma Erwen laser particle size analyzer on the spray characteristic test bench. The average diameter and size distribution of diesel and biodiesel droplets were studied. The cumulative volume distribution and characteristic diameter are compared. The experimental results show that the average diameter and characteristic diameter of biodiesel droplets are larger than those of diesel oil under the same injection pressure. The atomization quality of biodiesel is worse than that of diesel.
