Multi-response optimization to improve the performance and emissions level of a diesel engine fueled with ZnO incorporated water emulsified soybean biodiesel/diesel fuel blends

The present study examines the effect of silicon dioxide (SiO2) nano-additives on the performance and emission characteristics of a diesel engine fuelled with soybean biodiesel. Soybean biofuel was prepared using the transesterification process. The morphology of nano-additives was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The Ultrasonication process was used for the homogeneous blending of nano-additives with biodiesel, while surfactant was used for the stabilisation of nano-additives. The physicochemical properties of pure and blended fuel samples were measured as per ASTM standards. The performance and emissions characteristics of different fuel samples were measured at different loading conditions. It was found that the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) increased by 3.48–6.39% and 5.81–9.88%, respectively, with the addition of SiO2 nano-additives. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions for nano-additive added blends were decreased by 1.9–17.5%, 20.56–27.5% and 10.16–23.54% compared to SBME25 fuel blends.

This study describes preparation of biodiesel through micro emulsification of diesel with 15, 25 and 35% of used mustard oil and 2.5% of Triton-X100 as surfactant by volume. The prepared blends are designated as B15; B25 and B35.The physiochemical properties of blends were tested as per American Society for Testing and Materials (ASTM) standard and compared their properties with diesel. Experiments were conducted on single cylinder, 4 strokes, water cooled direct injection diesel engine fuelled by three different micro emulsified fuel blends. The results indicated that a slight decrease in the brake specific energy consumption and increase in brake thermal efficiency for B35 fuel compared to diesel fuel operation. Reduction in HC, CO<sub>2</sub>, CO and nitric oxide emission was observed for all test fuels compared to diesel fuel.
