Abstract

Biodiesel as well as some nanocatalysts as an additive to diesel fuel can improve the performance and reduce engine emissions. In this study, after production of biodiesel from residual edible oils and conforming its specifications with standard, biodiesel produced in different volume ratios with diesel fuel was prepared. Magnetic nanofluid as an additive was added to the biodiesel mixture in two volume ratios of 0.4 and 0.8% and short-term engine tests were performed to investigate the performance parameters and exhaust emissions of diesel engine for pure diesel and fuel mixtures at different loads. Statistical analysis of the experimental data based on Taguchi method was performed using MiniTab software and also linear regression analysis using SPSS software as a completely randomized factorial design. After making sure that the main effects of the fuel and engine components were significant and their interactions on the measured parameters (braking power, torque and specific fuel consumption), the mean of engine fuel and engine components were compared. Experiments were carried out on a single-cylinder diesel engine at three engine speeds of 2000, 2500 and 3000 rpm under full load conditions. The results showed that using nanofuels and increasing the concentration of nanoparticles in biodiesel 3B fuel increased power and torque at all engine speeds and reduced the specific fuel consumption compared to pure biodiesel
