Influence of Injection Parameters on Performance and Emission of DI Diesel Engine Fuelled by 1,4-Dioxane Emulsified Fuel 2020-28-0518

The pattern of utilizing the water/diesel emulsion fuels in engines had been given great importance due to its ecological and exhaustion of petroleum reserves. This investigation displays the impact of 1,4-dioxane emulsified fuel on performance and emissions at various operating pressures. 1,4-dioxane emulsified fuel (DWSD10) was prepared with 10% 1,4-dioxane, 10% water, 0.2% surfactant and 79.8% diesel. To estimate the engine performance and emissions, the engine was operated with 180 bar, 200 bar and 220 bar operating pressures and the output was equated with diesel fuel operating on normal pressure of 200 bar. BTE of 1,4-dioxane emulsified fuel at 220 bar was higher when compare with diesel fuel. CO, HC and BSEC were lower at 220 bar on par with diesel fuel. However, NO_x was increases for the higher operating pressure. Overall, except NOx, at higher injection pressure (@220 bar) the 1,4-dioxane emulsified fuel outperforms the diesel fuel in terms of emission and performance.
