Abstract: | The main properties and engine emissions of low blending rate soybean oil methyl ester blended with diesel from 5 to 30 wt% were compared and analyzed. The experimental results show that, compared with diesel fuel, with an increase in the soybean oil methyl ester percentage in the blends, distillation temperature at 50%, flash point, kinematic viscosity, specific gravity, gelatine content, carbon residue, acidity and ash increase while a cold filter plugging point, solidifying point and copper corrosion keep constant, sulfur content decreases, smoke density and HC decrease while NOx emission increase, CO increases at 2,200 r/min but decreases at 3,400 r/min. |
