Experimental investigations on gaseous hydrogen supplemented Aleurites Fordii biodiesel in a direct injection diesel engine for performance enhancement and reduction in emissions

The exponential increase in energy demand and the unavailability of fossil fuels and environmental issues accelerated researchers' work on alternative fuels. Aleurites Fordii biodiesel is one such alternative biofuel derived from its biomass can sequestrate the carbon dioxide and emit the oxygen which balances the environment is being considered as pilot fuel supplemented with 5% and 10% high energy gaseous hydrogen in a 4 S, 3.5 kW, constant speed, water-cooled, constant speed engine. Performance, combustion and exhaust out emissions were analysed. All precautionary steps involved in handling the gaseous hydrogen-like NFPA Class I Division 2 Group B standards were considered. 10% gaseous hydrogen supplemented Aleurites Fordii biodiesel shown better performance and reduction in emissions. Further, same results were compared with 90 degrees C preheated Aleurites Fordii straight vegetable oil, pure Aleurites Fordii biodiesel, 5% hydrogen supplemented Aleurites Fordii biodiesel and conventional petro-diesel operations.
