Diesel engines, one of the biggest sources of global warming and harmful exhaust emissions, constitute an important research topic in terms of reducing dependency on fossil fuels and environmental damage. The limited life of fossil-based fuels and the increase in energy demand increase the need for sustainable energy solutions that require the evaluation of waste. In this context, the evaluation of pyrolytic oil obtained from waste tires and waste transformer oil that has completed its service life as alternative fuels has great importance both environmentally and economically. In this study, fuel mixtures were created by mixing pyrolytic oil obtained from waste tires, waste transformer oil and diesel fuel in different proportions. In addition, cetane number improver was added to the prepared mixtures and these mixtures were tested in a single-cylinder diesel engine. Mixing the components used in the blends in different proportions allowed a detailed examination of their effects on engine performance and exhaust emissions. Experimental results showed that changes in the ratios of pyrolytic oil and transformer oil directly affect the performance parameters of the engine such as power, fuel consumption and thermal efficiency. At the same time, it has been determined that certain mixtures provide reductions in emission values, especially the release of harmful gases such as CO and NOx is significantly reduced. These findings reveal that optimization of fuel mixture ratios is critical for both environmentally friendly fuel production and engine performance.
