The pilot fuel considered for this study is Algae biodiesel. A mono-cylinder water-cooled diesel engine is tested for three different pilot fuel injection timings (23 degrees BTDC, 26 degrees BTDC, and 29 degrees BTDC) and five different engine loads (20%, 40%, 60%, 80%, and 100%). For a dual fuel operation, a maximum brake thermal efficiency of 28.21% and an 85% replacement of liquid charge was achieved at pilot fuel injection timing of 26 degrees BTDC and 100% load based on the experimental results. For the same setting of injection timing of 26 degrees BTDC, the emissions of CO and HC were significantly reduced by 12.12% and 36.13%, respectively, at the 80% load setting. While response surface optimum was found at 72.81% load and 25.73 degrees BTDC Injection timing. At this optimal operating parameter setting, a significant reduction of CO, HC, and NOx emissions by 20.98%, 29.15%, and 1.91%, respectively, was obtained while maintaining a comparable brake thermal efficiency of 25.06% and a replacement of liquid charge by 72.15%, respectively. Thus, a biodiesel-hydrogen dual-fuel diesel engine is one of the green solutions for power generation.en10.1016/j.fuel.2023.129841info:eu-repo/semantics/closedAccessHydrogenAlgae biodieselDual fuel technologyResponse Surface MethodologyClean Development MechanismCombustion CharacteristicsEmission CharacteristicsSingle CylinderPerformanceDutyExhaustCocombustionParametersVibrationSmokeArticle3572-s2.0-85172244000WOS:001085361200001Q1Q1
