    Biodiesel Fuels Produced from Poppy and Canola Oils, Experimental Investigation of the Performance and Emission Values of the Samples Obtained by Adding New Types of Nanoparticles
    (Maik Nauka/Interperiodica/Springer, 2022) Demirpolat, Ahmet Beyzade; Uyar, Muhammed Mustafa; Arslanoglu, Hasan
    In this study, poppy oil and canola oil were subjected to acid and base catalysed transesterification reactions and biodiesel fuels were obtained. In addition, tests of the additive-free state of standard diesel fuel and biodiesel were also performed for comparison. These fuels have been subjected to performance and emission tests in a direct injection three-cylinder diesel engine. These values are compared with the values of standard diesel fuel. According to the results obtained from engine tests, the biodiesel produced with poppy, canola oil, and nanoparticle additives generally showed similar properties with diesel fuel. In terms of volume, the increase in the biodiesel ratio in diesel fuel has been found to increase the specific fuel consumption and exhaust outlet temperature values. By using biodiesel-containing fuels, compared to diesel fuel, CO, HC, smoke emissions decreased, NOx, CO2, and O-2 increased. Biodiesel fuel samples with additives were obtained by adding a new type of CuO nanoparticle produced in the study to biodiesel-containing fuels. Comparison of the biodiesel samples and the fuel created by adding nanoparticles to these samples with the addition of nanoparticles, it has made a great contribution in the desired direction in the consumption of approximately 20% CO, 27% HC, 29% smoke (soot), and 16% specific fuel consumption. As an innovation to the literature, improvement in combustion and performance characteristics of biodiesel with nanoparticle additive, decrease in emission values and positive effect of this decrease on the environment were observed as a result of the study.

    Investigation of performance and emission values of biodiesel fuels produced by adding ZnO nanoparticles as additives to waste sunflower and Kohnu grape seed oil
    (Springer, 2023) Uyar, Muhammed Mustafa; Demirpolat, Ahmet Beyzade; Arslanoglu, Hasan
    Biodiesel was produced by adding ZnO nanoparticles as additives to the waste sunflower and kohlrabi grape seed oil. As a result of the examination of the produced fuels, it was observed that there was a decrease in CO, HC, and smoke emissions and an increase in NOx, CO2, and O-2. When these nanoparticle-doped fuel samples were compared with standard diesel fuel, improvements in emission values were obtained by adding ZnO nanoparticle additives to biodiesel fuel. These improvements were observed as a 35% reduction in CO, a 40% reduction in HC, and a 45% reduction in smoke (soot). The reason for this is that the nanoparticle additive increases the heat transfer coefficient of biodiesel fuel. Accordingly, it has a positive effect on in-cylinder temperature, pressure, ignition delay, and combustion time. It was concluded that the nanoparticle additive added to the fuel together with the observed reductions in emission rates provides a great benefit to the environment. In addition, an 11% reduction in specific fuel consumption was observed thanks to this nanoparticle additive. An improvement was observed in the emission values to the environment.
