Investigations on nano additives and modifications of piston bowl geometry of diesel engine using biofuel blends

Abstract

The fast depletion of petroleum fuel stocks and its serious impacts on environment have motivated to seek the environment friendly alternative energy sources In India more than 85 of petroleum fuels are imported from foreign countries Hence the energy security has become a critical issue in India Therefore the research and development efforts have been made to identify the possible indigenous renewable energy sources Among the indigenous renewable energy options the bio energy is the most suited energy resource for the internal combustion engine applications Presently the use of bio fuels is getting research attention due to its material compatibility and environment friendly in nature Moreover the uses of bio fuel/diesel blends have improved the performance and engine life due to its favourable thermal and lubrication properties respectively This research work focus on use of bio diesel and bio fuel blends extracted from trans esterification and catalytic cracking methods respectively The grape seed methyl esters were extracted through trans esterification processes in the presence of potassium hydroxide as catalyst The grape seed bio-diesel was blended with diesel in the ratio of 0 100 25 75 50 50 75 75 and 100 0 by volume for performance evaluation In addition the bio fuels from grape seed and date seed were extracted by catalytic cracking processes in the presence of fly ash as catalysts newline
