Enhancement of Performance and Reduction in Emissions of Hydrogen Supplemented Aleurites Fordii Biodiesel Blend Operated Diesel Engine

Abstract

The exponential growth in demand for energy and the non-availability of fossil energy and the immediate concern about environmental problems have intensified alternative fuels researchers' work. Aleurites Fordii (AF) biodiesel is a biomass-derived biofuel that can sequester carbon dioxide and release environmentally balancing O2 and is thought to blend in 5-15% range with conventional petro-diesel fuel. Further, these blends were tested with 5% and 10% of total energy with GH2 in a 4-stroke, 10 kW, water cooled, naturally aspirated, constant speed, in-direct injection compression ignition engine performance enhancement and reduction in emissions. All safety-related issues in handling and storage of GH2 were considered as per National Fire Protection Association recommended standards. 5% AF biodiesel blend with 5% GH2 (AFBD5H5) shown better performance with minimum emissions except NOx was identified and compared with 90C pre-heated AF Straight Vegetable Oil (AFSVO), pure AF biodiesel (AFBD), 5% hydrogen supplemented AF Biodiesel (AFBD5H) and conventional petro-diesel operations.
