Abstract
In this study, the biodiesel (ethyl ester) from sunflower oil was prepared by a transesterification method. Biodiesel has properties different from those of diesel fuel. The effects of biodiesel addition to diesel fuel were examined on the performance and emissions of a DI diesel engine equipped with turbocharger at full engine load. Increase in brake specific fuel consumption (BSFC) and decrease in brake power for biodiesel and its blends were observed compared with diesel fuel at 1400 rpm. Also, CO, NOx and UHC were increased while smoke was decreased. At 2000 rpm, the results indicated that engine fueled with biodiesel and its blends increased the brake power and BSFC. Also, CO, CO2, UHC and smoke emission were reduced, while NOx emission was increased.
