摘要：

The study on the soot emission characteristics of diesel engine fueled with diesel or biodiesel was conducted, and a predictive formula based on hiroyasu soot submodel for soot emission of the biodiesel was proposed. Based on the measured indicator diagram, a quasi-dimensional particulate emission model for the engine fueled with biodiesel was established by combining a fuel spray impinging and air entrainment submodel, droplet's evaporation and combustion submodel, the heat transfer submodel and hiroyasu soot submodel, and the in-cylinder soot mass was calculated. The results indicated that the theoretical results calculated agreed well with experimental results, and the established model was suitable for soot emission prediction of diesel engine fueled with oxygenated fuels. The ignition start of biodiesel in engine was early to reach the trigger temperature of soot formation, so soot emission increased in the initial stage of combustion. Since the oxygen concentration at combustion area was high due to the oxygenated properties of biodiesel, the peak and final emission value of soot was reduced by more than 50% compared with that of 0# diesel. ©, 2015, Editorial Office of Acta Petrolei Sinica (Petroleum Processing Section).
