| Popis: | 100 The effects of type and concentration of surfactants on emulsification properties and diesel engine emission characteristics of an emulsion prepared by a phase-inversion temperature method were investigated in this study. Non-ionic surfactants were used for the emulsion formation of silicon oil with de-ionic water at the first experimental stage. The engine performance and emission characteristics of soybean biodiesel, and emulsions prepared by mechanical stirring and phase-inversion temperature methods, respectively under constant engine torque and varied engine speeds were studied at the second experimental stage. The experimental results show that the emulsion prepared by the method of phase-inversion temperature had higher O2 emission, NOx emission and exhaust gas temperature while lower CO emission than the emulsion by mechanical stirring. The soybean biodiesel was found to have the lowest fuel consumption rate, brake specific fuel consumption, and CO emission while the highest exhaust gas temperature, NOx emission, and O2 emission among those three fuels. |
