Emulsified Fuels:Current State and Perspectives

Emulsion fuel is an attractive alternative fuel, thereby providing the potential to reduce particulate emissions in compression ignition engines. In this review the properties and emulsion of water with fuel are discussed. Special emphasis is placed on the factors critical to the potential commercial use of these emulsion fuel. These factors include properties such as stability, viscosity and lubricity, safety and materials compatibility. The effect of the fuel on engine performance, durability and emissions is also considered. The formulation of additives to correct certain key properties and maintain stability is suggested as a critical factor in ensuring fuel compatibility with engines. However, maintaining vehicle safety with these emulsions may entail fuel tank modifications. Further work is required in specifying acceptable fuel characteristics, confirming the long-term effects on engine durability, and ensuring safety in handling and storing Fuel emulsions using represents a method of diminution of pollutant emissions resulted from burning of liquid petroleum fuels. The selection of fuel emulsions with a high stability and improved flowing characteristics represents the introducing method of this type of fuels on market Both the consideration of the thermo-chemical properties of the tested fuels and the computations of a chemical equilibrium model were helpful for the results analysis.
