Abstract
This study describes the effects of diesel–biodiesel–bioethanol blending fuels on the combustion and emission characteristics of a compression ignition engine. The experiments were investigated for various blending ratios and various fuel injection parameters. In this study, biodiesel fuel was blended not only to prevent phase separation between bioethanol and diesel but also to compensate for the low viscosity of bioethanol. The bioethanol blending ratio is restricted up to 30 vol. % to maintain the ignition characteristics. The results showed that the ignition delay was extended and that the fuel consumption and the maximum rate of pressure rise deteriorated with increasing bioethanol blending ratio. In addition, the diesel–biodiesel–bioethanol fuel reduced the indicated specific soot emissions. As the bioethanol blending ratio is increased, the indicated specific carbon monoxide (CO), the indicated specific unburned hydrocarbon, and the indicated specific nitrogen oxide emissions increased slightly.
