A novel fuel which is an emulsion of water in at least one hydrocarbon, and which contains an emulsifying system containing at least one sorbitol ester, at least one fatty acid ester and at least one polyalkoxylated alkylphenol. The system has an overall HLB of between 6 and 8, and the emulsion contains droplets of aqueous disperse phase which are less than or equal to 3 .mu.m in size.
