Identification of best additive using the selected ratio of ethanol-diesel-based emulsified fuel

The present universal problem is to identify an alternate fuel, for the current existing engines without any modification, with better performance and less emission. Emulsion technique is the best method to solve the above-mentioned problem. Emulsified fuels with a surfactant are familiar nowadays. The addition of oxygen-enriched additives in the emulsified fuels gives good results than the previous one. Usually, NOx emission is high for the emulsified fuels, when compared with diesel fuel. But additive-added emulsified fuels emit less NOx than diesel. Based on this, the present work has been carried out using oxygenenriched additives: diethyl ether, hydrogen peroxide and dimethyl ether (DME). The water-in-oil-type emulsion method is used to prepare the emulsified fuel. The test results have shown that DME gives the best performance and less emission, with the selected emulsified fuel ratio of 50D: 50E, when compared with the other two additives.
