An innovative Emulsification Engine Feeding System (EEFS) has been developed in the Roma Tre University Fluid Machinery Lab. It is based on an emulsification loop, where fuel and water are fed in real time with the emulsion injection. Thus no chemicals to stabilize water in diesel fuel or ethanol in diesel fuel emulsions, are used. The system assures the emulsion stability level sufficient for the emulsion to be injected inside the engine. Tests carried out on the EEFS, developed for a 6 cylinder, four stroke, 12.88 litres, 382 kW diesel engine, have shown the good quality of the emulsion in terms of the water droplet diameters and volumetric mixing ratio, at the various engine loadings and rpm. A water separation section that operates for the duration of the engine shutdown is a unique feature of the EEFS to avoid corrosion during steps.
