Experimental tests have been carried out to evaluate the performance and gaseous emission characteristics of a diesel engine when fuelled with vegetable oil and its blends of 25%, 50%, and 75% of vegetable oil with ordinary diesel fuel separately. Tests on ordinary diesel fuel have also been carried out for comparison purposes. A series of tests are conducted and repeated six times for each of the test fuels. The engine works at a fixed speed of 1500rpm, but at different loads respectively, i.e. 0%, 25%, 50%, 75% and 100% of engine full loads. The performance and the emission characteristics of exhaust gases of the engine are analyzed and compared. The experimental results show that the basic engine performance – power output and fuel consumption are comparable to diesel when fueled with vegetable oil and its blends. The emission of nitrogen oxides (NO_x) from vegetable oil and its blends are lower than …
