Abstract:
The dilferenee of physieal properies between biodiesel and diesel has impact on the spray charae-teristies of diesel engines. In this paper, diesel and biodiesel made from soybean erude oil were blended indiferent proportions. The physical properly indexes of blended fuel such as density , kinematie viseosity, sur.laee tension and distillation temperalure were tested. Meanwhile, spray charaeteristies of biodiesel and diesewere measured in amosphere environment by sporls cameras and Malvern pariele size analyzer. The resultindieate that the density, kinematie viseosity, surfaee tension and distillation temperature of biodiesel are high.er than those of diesel. The spray eone angle of biodiesel at different time is less than that of diesel. Converse.ly, penelration distanee is longer than that of diesel. Compared with diesel, biodiesel’s Sauter mean diameterand representative diameter inerease. Simultaneously , the curve of drop size distribution and aecumulative vol.ume distribution shifl to the direetion of large particles, which indieates that atomization quality of biodiesel ispoorer than that of diesel.
