Impact of Natural Additives on the Performance of a Bio-diesel Fuelled Diesel Engine

The biodiesel is a renewable alternative to the fossil diesel as the properties of the bio-diesel is like to the fossil diesel. However, the bio-diesel have lower volatility and has lower oxidation stability. Hence, in this work we have chosen the Black seedoil, clove oil + Pg and turmeric oil as a natural additive for the honge biodiesel. Anti-oxidative properties and stability of ethanolic extracts of Black seed oil, clove oil + Pg and turmeric oil is studied. Along with that constituent’s black seed,turmeric oil and clove oil+ accounting a 90% of essential oil content which preferred as additive to the biodiesel. Also, we calculated the effect of these additives on the fuel properties of the bio-diesel and its impact on compression ignition thermal efficiency and exhaust emissions. The additive concentration ratio of binary anti-oxidants is the key factor to get best synergy for greatest stabilization. In an engine, temperature has reaction completeness is the most critical fuel quality parameter as well as engines’ durability and reliability. By adding natural additives to the biodiesel, as the amount of concentration increases it led to reduction in hazardous emissions through engine exhaust like NOx, CO2, HC s, CO decreases. But the O2 content increases in a engine exhaust. All these emissions are as compared with conventional diesel which gives the best results for lowering the environmental pollution.As the proper qualities of biodiesel blends met by adding these naturally available additives, these biodiesel blends can be used in most modern engines.
