Spray Characteristics and Droplet Micro-Explosion of Water in Diesel Emulsion
This paper highlights the potential usefulness of water-in-diesel emulsions when exposed to high-temperature, thereby improving the air�fuel mixing process utilising micro-explosion resulting from multi-component fuel combustion.Although the high injection pressure significantly affects the spray...
