TECHNOLOGY PERFORMANCE MEASUREMENT OF FOUR STROKE CI ENGINE USING PREHEATED NEEM BIO DIESEL

B20 and B40 fuel with preheating show improvement in brake thermal efficiency by 24% and 10.54% respectively compared to diesel fuel. B20 and B40 fuel with preheating show decrease in BSEC by 20.49%, and 10.82% respectively compared to diesel fuel. EGT increases with increase in bake power for all fuels. B20 and B40 fuel with different preheating show decrease in CO emission by 1.8% and 2.7% respectively compared to diesel fuel. HC emission is decreased by 18%, 20.48% and 39.75% for B20 and B40 fuels respectively compared to diesel fuel at no load.
