Summary:

Fuel crisis and environmental concerns have led to look foralternative fuels of bio-origin sources such as vegetable oils,which can be produced from forests, vegetable oil crops and oilbearing biomass materials. Vegetable oils have energy contentcomparable to diesel fuel. Straight vegetable oils posed severaloperational problems and durability problems when subjected tolong-term usage in CI engine. These problems are attributed tohigher viscosity and lower volatility. The viscosity can be broughtin acceptable range by (i) converting the vegetable oil into methylester, (ii) blending of oil with diesel fuel, (iii) blending of oilwith alcohols or (iv) increasing the fuel temperature to over 200°Cusing exhaust gas waste heat. Reduction of viscosity by blending orexhaust gas heating saves the chemical processing cost oftransesterification. In this work, performance and emissionparameters of a single-cylinder, four-stroke naturally aspirated,unmodified diesel engine operating on neem oil and its blends of 5vol%, 10 vol%, 15 vol% and 20 vol% with ethanol, 1-propanol,1-butanol and 1-pentanol are evaluated and compared with dieseloperation. The measured performance parameters are brake thermalefficiency, brake specific fuel consumption and engine exhaustemission of CO, HC, NOx and smoke intensity.Significant improvements in performance parameters and exhaustemissions have been observed for the addition of these organiccompounds with neem oil
