In this paper, the assessment of puffing and micro-explosion occurrence in emulsion drops with differentwater percentage is studied. The emulsified fuels are formulated using micro channel emulsifier, rapeseedoil and diesel fuel as continuous phase, as well as water and Sorbitan Sesquioleate as surfactant. Theformulated dispersed systems are covered under different experimental factors such as water ratio andsurfactant percentage. The puffing occurrence is reported in all emulsified fuels tested (i.e. with andwithout surfactant). A sudden puffing and highest number of occurrence is noted when the water amountincreases in all emulsified fuels. The micro-explosion phenomenon is only noted in emulsified fuelformulated without surfactant.
