A theoretical model was developed to evaluate the performance, characteristics and combustion parameters of vegetable oil esters like Jatropha, Mahua and Neem oil and they are compared to diesel fuel. The predicted results of these fuels are compared with experimental result and also compared with the result of diesel fuel for the validity of the theoretical model. The combustion characteristics and performance parameters are predicted for different vegetable oil esters and for various injection timing. From the predicted results, it is found that the heat release and work done are reduced by about 4% for Jatropha, 6% for Mahua and 8% for Neem oil esters when compared to diesel. However, slight increase is observed for specific fuel consumption. The experimental work is carried out in a single cylinder computerized diesel engine test rig, which develops 5.2 kW at 1500 rpm and loaded by eddy current dynamometer at various Injection timing. The harmful pollutants such as HC, CO, NOX and smoke are reduced in the vegetable oil esters than that of diesel fuel. From the investigation it is concluded that the performance of vegetable oil esters such as Jatropha, Mahua, and Neem are much better. Thus the developed model is highly capable for simulation work with bio-diesel as a suitable alternative fuel for diesel.
