With this study, we want to analyse the different techniques used to develop emulsions and then apply a new mechanism to manufacture a water-in diesel emulsion that would be stable for a relatively long period. After the research on previous studies, we confidently applied the knowledge acquired during the time of personal study and the research to develop a system that brought us to keep in a semi-stable state an emulsion of water and diesel for a period of 24 hours. In this research we are not focusing on one of the two aspects that should be noted once you study emulsions: we are trying to develop a stable emulsion through the employment of vibrations without considering the employment of such emulsion in an engine, for the moment.
