This work presents results of an experimental investigation of a dual pressure swirl injector for atomization of biofuels. An injector prototype was built for comparative testing with distillate water, hydrated ethanol and B100 soy biodiesel. The atomization characteristics of the injector were obtained in a test bench specially developed for this research. The discharge coefficients, the average droplet diameters, the distribution of droplet sizes, the spray cone angles, the spray mass distributions, and the effects of operating pressures and mass flow rates of biofuels on the performance of the injector were determined using different experimental techniques.ഀ
