Abstract

In the present work approach to reduce the viscosity of the bio diesel and in order to improve the calorific value of bio diesel extracted from the mango seed oil 1, 4 dioxane has been used as a fuel additive. The methyl ester mango seed oil is prepared by employing transesterification process and blended with 2.5 %, 5%, 7%, and 10% of fuel additives blended with bio diesel. The optimum blend ratio of fuel additives was identified and 10% of additives shows better performance than others. The experiment was conducted in a single cylinder DI diesel engine coupled with eddy current dynamometer. From the experimental investigation it is found that, viscosity has been reduced up to 0.5% and it shows marginal increase in calorific value. The brake thermal efficiency for 10% additive fuel is slightly increased and significantly reduced NOx emission about 200 ppm.
