In the present investigation, bio-oil is extracted from lemongrass through steam distillation process, Single stage trans esterification using methanol and potassium hydroxide at molar ration of 1:8 yielded lemongrass biodiesel. The biodiesel was characterized using Gas chromatography Mass spectrometry and Fourier transforms infrared spectrometry analysis and found to have Behenic and Stearic acid in prominent proportions. The cetane number and calorific value was enhanced by ultrasonicating carbon Nano-tubes at various proportions. Kirloskar TV1 compression ignition engine coupled with eddy current dynamometer was employed to analyse the combustion, performance and emission characteristics. Addition of carbon Nano-tubes significantly affected the ignition delay and combustion duration. D80LGB20CNT100 fuel blend exhibited higher in-cylinder pressure up to 65.144 bars along with enhanced rate of heat release upto 73.953 kJ/kg at full load condition. Higher brake thermal efficiency with notable reduction in unburned hydrocarbon and smoke was seen with elevated levels of carbon-monoxide and oxides of nitrogen.
