The smoke and hydrocarbon emission of NBM blend at 25 ☌A bTDC is reduced by 40% and 38.07%, respectively, related to diesel. Nitrogen oxides and carbon monoxide of a blend of B20 + D80 + 30% n-butanol (NBM blend) at 21 ☌A bTDC were reduced by 49 percent and 5.88 percent, respectively, when a relative to diesel fuel. The injection timing was varied between 21 ☌A bTDC and 25 ☌A bTDC. About 20–30 vol.% of n-butanol blended with 80 vol.% of diesel and tested. In this experimental investigation, a Blend of Mahua biodiesel mixed with n-butanol was used as test fuel in a conventional engine. Doping of an antioxidant, preferably n-butanol eliminates these harmful emissions from the diesel engine. This is due to its desirable properties such as rapid growth rate, higher productivity, and the ability to utilize CO 2 into fuel. Mahua biodiesel blend has also been considered a safe renewable fuel for conventional engines.
Hence, it has a necessity a reduction in the use of diesel fuel and addition of suitable biodiesel. Ever growing demand and use of diesel engines in various fields cause the emission of exhaust gases like NOx and CO that lead to serious environmental pollution and hazards like global warming, respiratory problems. The utilization of non-renewable energy sources leads to long-standing unfavorable consequences on human health and environmental issues.
