Abstract: The current work describes the derived energy and exergy of nickel oxide nano additives in Neem biodiesel blend at varying engine fuel injection timings. A VCR engine was used for combustion and energy analysis. Nickel oxide nano additives were synthesized and subjected for significance by using characterization techniques such as XRD, FESEM and EDS. Nano additives were doped in neem oil methyl ester blend with diesel in volumetric proportion of 25:75 %vol. The combustion analysis pertaining to Heat release rate and cylinder pressures were obtained at varying crank angles and were peak HRR and Pressures rates were found for Nickel oxide dosed fuels for 27 deg. bTDC. The amount of energy consumed for net-work done reduced with advancement of fuel injection timing from 23° to 27° bTDC and the reduction for Diesel, NB25, NB25 + 25 ppm of NiO and NB25 + 50 ppm of NiO was found to 1.1%, 1.03%, 3% and 3.3.% respectively. Exergy destruction was found to retarding with the usage of nickel oxide nanoadditives. The level of exergy destruction found for Diesel, NB25, NB25 + 25 ppm NiO and NB25 + 50 ppm of NiO with advancement of Injection timing from 23 deg. To 27 deg. bTDC was found to around 1.2%, 1.6%, 1.7% and 1.75% respectively.
