Abstract
Recently, biodiesel is gaining potential as an alternate for petroleum based diesel fuel owing to the risk of extinction of fossil fuel resources and environmental consideration. Biodiesel offers many benefits such as less damage than petroleum diesel, potential to diminish the amount of greenhouse gases, non-toxic and biodegradable, etc. Hence, the objective of current investigation is the replacement of diesel fuel with eucalyptus oil. For this, eucalyptus oil was mixed with diesel fuel in distinct proportions by volume and utilized as fuel in a single cylinder, four stroke diesel engine, in order to predict the influence of biodiesel on engine emission and performance characteristics. The result depicts that Brake Specific Fuel Consumption (BSFC) for Eu.100A and Eu.100B in case of euclyptus biodiesel was 8.18% and 4.05% lesser than diesel at full load condition. However, the Brake Thermal Efficiency (BTE) for Eu.100A and Eu.100B, was 9.62% and 4.87% greater than diesel at full load. In addition, the engine emissions in terms of HSU were also found to be lower for all blends and all load condition than diesel fuel.
