| Biodiesel, as a renewable and environmentally friendly alternative to conventional diesel fuel, has gained significant attention due to its potential to reduce greenhouse gas emissions and mitigate the depletion of fossil fuel reserves. In this study, statistical analysis was employed to evaluate the performance of a diesel engine using different biodiesel fuels, engine load, and engine speed, along with their interactions in terms of exergy efficiency. The first and second laws of thermodynamics were applied to analyze the energy and exergy of a direct injection, four-stroke, single-cylinder, air-cooled diesel engine. Biodiesel fuel was prepared from waste cooking oil, and factorial experiments were conducted with a completely randomized design at engine speeds of 1800-2200 rpm, with five levels of biodiesel fuel blend. Diesel and biodiesel fuel blends, with biodiesel content ranging from 0% (B0) to 20% (B20), were tested under 50% and 100% engine loads to apply the first and second laws of thermodynamics. The interaction of independent parameters on energy and exergy parameters for the controllable volume of the diesel engine was investigated using data obtained from the experiments. The results showed that engine speed and biodiesel fuel composition significantly affected exergy efficiency at the 1% level. Additionally, triple interactions of independent variables were significant only for engine cooling exergy (heat loss exergy) and not for other dependent variables. Similar trends were observed for energy efficiency. | ||
