Optimization of Biodiesel Yield and Performance Investigations on Diesel Engine Powered with Hydrogen and Acetylene Gas Injected with Enriched Jojoba Biodiesel Blend
International journal of hydrogen energy(2024)
Abstract
Jojoba biodiesel has turned into one of the best adequate renewable energy sources owing to its ability to substitute traditional fossil fuels in IC engines. Even though Jojoba biodiesel (JOBD) mitigates destructive pollutants, engine performance is not comparable to that of regular diesel. To correct this limitation, the impacts of hydrogen and acetylene gas introduction with Jojoba biodiesel blend (JB20) on the combustion, emission, and performance features of a CI engine were investigated. The properties of fuel (JB20) were determined and different experiments on the engine were performed in dual fuel mode using hydrogen gas and acetylene gas at diverse flow rates, and the outcomes were compared. The hydrogen gas and acetylene gas were introduced separately at the inlet manifold of the engine with a volume flow rate of 4 p.m. and 8 lpm respectively. According to the results of the experiments, JB20 + 8 lpm of H2 had a higher BTE of 7.18% and 3.14% when compared to JB20 and diesel fuel correspondingly and acetylene mixed JB20 fuel was improved by 2.61% percent with 8 lpm in comparison with JB20 fuel sample. The addition of hydrogen (4 lpm and 8 lpm) into the JB20 fuel bsec was reduced by 6.78% and 13.71% compared to the diesel, 28.65%, and 34.96% than the JB20 fuel. The induction of hydrogen and acetylene gas to the JB20 fuel improved the heat release rate (HRR) and cylinder pressure (CP) equated with JB20 fuel. Further, a considerable reduction was found in CO, HC, and smoke exhaust pollutants at 11.85% 18.4% % and 7.52% respectively but NOx emissions were significantly improved by 2.55% compared to JB20 with hydrogen injection at 8lpm. It concludes that hydrogen and acetylene gas are feasible diesel engine fuel substitutes. (c) 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
