Evaluation of Engine Performance using Biofuel Blends derived from Pongamia

Chandra Kumar R, Dr M M Benal, Dr B Durga Prasad

Abstract


The petroleum products are from non-renewable source, which is available in the nature in limited quantity. Also Air pollution is becoming a major concern in recent times in many countries. Hence there are studies conducted across the globe on using alternative fuels from renewable resources, which can replace the petroleum products effectively. Biofuels are promising renewable alternative for petroleum based fuels. Hence In this study, testing of a diesel engine has been carried out with different percentages of Pongamia derived biofuel and diesel blend. The variations of Specific Fuel Consumption and Brake Thermal Efficiency with respect to Power Output have been studied. Also emission characteristics namely smoke density and gaseous pollutants like unburnt hydrocarbon have been studied. Results indicate that 20% biofuel blend can be used for short term engine operations.
