Abstract
The results of four different blends (20%, 5% each) based on diverse sources of energy (Soybean oil, Jatropha, spirulina, and waste oil) were compared to conventional fuel. The tests carried out in total accordance with the American Society for Testing and Materials (ASTM) guidelines. Test results were numerically assessed using Diesel-RK software. Specific fuel consumption, thermal efficiency, heat release rate, emissions of Particulate matter, CO2 emissions, NOx emissions, and smoke emissions were all analyzed. Diesel, B20 SME, B20 Jatropha, B20 spirulina biodiesel and B20 Waste plastic pyrolysis oil blends on volume basis were tested at 100%, 75%, 50%, and 25% load on a single-cylinder diesel engine. The findings indicate that Spirulina B20 lowers cylinder pressure, brake thermal efficiency, indicated thermal efficiency, particulate matter, and nitrogen oxides by 6.86%, 4.18%, 2.002%, 6.4%, and 9.95% respectively. The experimental results were validated to numerical findings from the simulation software Diesel-RK under the similar operating conditions. As a result, the current research focuses on evaluating the engine's performance, combustion, and emission characteristics using a 20% diesel blend.
