Effect of Injection Timing In Reducing The Harmful Pollutants Emitted From CI Engine Using N-Butanol Antioxidant Blended Eco-Friendly Mahua Biodiesel

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 fields 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 CO2 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 n-butanol 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 23oCA bTDC. The injection timing is preferably between 21oCA bTDC and 25oCA bTDC. Nitrogen oxides and carbon monoxide are reduced by 49 percent and 5.88 percent, respectively, when a blend of B20 + D80 + 30% n-butanol is used at 21oCA bTDC relative to diesel fuel. The smoke and hydrocarbon emission of blend B20 + D80 + 30% n-butanol at 25oCA bTDC is reduced by 40% and 38.07%, respectively, related to diesel. The brake thermal efficiency for entire injection timing has been identified to be increased correlated to all other test blends. The brake thermal efficiency in blend B20 + D80 + 30% n-butanol of 25oCA 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.

INVESTIGATION ON DIESEL ENGINE FUELLED BY MAHUA BIODIESEL

The primary objective of this study is to discover the effects of injection timing on performance, emission and combustion characteristics effect of advanced and retarded injection timing of the engine fuelled with mahua oil biodiesel blends. The engine performance, combustion and emission characteristics of the mahua oil biodiesel blends (B20, B40, B60, B80and B100) are investigated in this experimentation without any modification of the diesel engine. At this advanced pressure t he efficiency of engine by means of CO, Unburned HC gases and smoke emissions with higher oxides of nitrogen was observed compared to diesel. The obtained results are compared with a neat diesel and mahua oil biodiesel blends are shown through the graphs. From this study, identifies optimum fuel blend of this work. Thus, the combustion of duration is similar in all variance in pressure. This research paved a way to bio-diesel in mahua oil mixture and draws best outcome in emission less and to maintain eco-friendly environment.
