Consuming non-renewable energy sources has genuine and long-standing unfavorable consequences on people's health, neighborhood networks and ecosystems, and also on the worldwide atmosphere. The burgeoning demand and use of diesel engines in various elds cause emission of exhaust gases like NOx and CO that lead to serious environmental pollution and hazards like global warming, respiratory problems, and so on, has necessitated a reduction in the use of diesel and addition of suitable biodiesel. Mahua biodiesel blend has also been considered as a safe renewable fuel for conventional engines. This is due to its desirable properties such as rapid growth rate, higher productivity, and the ability to utilize CO 2 into fuel. The introduction of an antioxidant, preferably n-butanol eliminates these harmful emissions from the diesel engine. In this experimental investigation, mahua biodiesel blend mixed with nbutanol has been used as test fuel in a conventional engine. Because of the special character n-butanol has been chosen for use with the mahua biodiesel blend. About 20-30 vol.% of n-butanol has been blended with 80 vol.% of diesel and tested. The manufacturer set injection timing was 23 o CA bTDC. The injection timing is preferably between 21 o CA bTDC and 25 o CA bTDC. Nitrogen oxides and carbon monoxide are reduced by 49 percent and 5.88 percent, respectively, when a blend of B20 + D80 + 30% nbutanol is used at 21 o CA bTDC relative to diesel fuel. The smoke and hydrocarbon emission of blend B20 + D80 + 30% n-butanol at 25 o CA bTDC is reduced by 40% and 38.07%, respectively, related to diesel. The brake thermal e ciency for entire injection timing has been identi ed to be increased correlated to all other test blends. The brake thermal e ciency in blend B20 + D80 + 30% n-butanol of 25 o CA bTDC is increased by 15.30%, when compared with diesel fuel. These promising results assure that mahua biodiesel blend containing antioxidant would be eco-friendly fuel.
