Experimental Investigation on Diesel Engine Using By-Products from the Vegetable Oil Industry

The world is presently confronted with the twin crises of fossil fuel depletion and environmental degradation. It is widely recognized that alternative diesel fuel produced from vegetable oil and animal fat can reduced the exhaust emission from CI engine without engine modification. In this present work biodiesel is converted from ground nut acid oil, it is by product of vegetable oil refinery waste. Experimental tests have been carried out to evaluate the performance, emission and combustion characteristics of a diesel engine when fuelled with different blends of Thermal cracked ground nut acid oil biodiesel (TCGAO) and ordinary diesel fuel separately. Tests on ordinary diesel fuel have also been carried out for comparison purposes. The experimental results show that the engine brake thermal efficiency and fuel consumption are comparable to diesel when fueled with B20TCGAO blends. The emission is lower for B20TCGAO blends compare to diesel and all other bio diesel blends.
