Abstract

The use of biodiesel in compression ignition engines results in decreased power and thermal efficiency due to biodiesel^s poor heating value. The advent of hydrogen gas with a high calorific value can help alleviate the biodiesel shortage. To blend the two fuels, Diesel Dual Fuel (DDF) technology is required. This research intends to investigate the performance and emissions of diesel engines powered by a mixture of biodiesel and hydrogen gas. The experimental method was conducted on a single-cylinder diesel engine operating with constant speed at 1000-4000 watt engine load. Hydrogen gas is injected into the intake manifold along with incoming air with flow variations ranging from 2.5, 5, 7.5, and 10 LPM. The testing results indicate that the inclusion of hydrogen gas can boost thermal efficiency, power, and torque by 40.34%, 2.41%, and 2.4%, respectively, as compared to biodiesel with a single fuel source. In addition to cutting fuel consumption and smoke by 85.71% and 70.55% respectively. The findings of the experiments indicate that the utilization of a diesel dual fuel system in diesel engines that are powered by a combination of biodiesel and hydrogen gas has a favorable impact on the enhancement of engine performance as well as the reduction of exhaust pollutants.
