摘要：In this study, waste cooking oil methyl ester (WCOME) and diesel were blended in 20, 40, 60 and 80% percentage volume basis. Biodiesel and the blends were tested in 4-cylinders, 4-strokes and direct injection diesel engine to investigate the emissions and performance at engine speeds of 600-3000 rpm under idle and full load. The result was compared to the data of petroleum diesel. The experimental data showed that the emissions of biodiesel and blends were much lower than B100. In comparison, the emission of biodiesel was more than 50% lower than B100. The average reductions were 76.19% for smoke opacity; and 97.62, 90.36 and 98.69% for brake specific emission factors of BS-HC, BS- CO and BS-SO2, respectively. The engine performances were also observed. Results showed that when WCOME were used both BHP and BMEP showed slight reductions about 8.63% compared to diesel. However, higher fuel consumption, had been indicated by the BSFC. The BSFCs of B100 were recorded to be 9.45% higher than biodiesel. The Highest BTEs were also recorded at a maximum average percentage of 19.93%.
