以直喷式柴油机喷油燃烧过程现象学描述为基础，建立了柴油机准维多区燃烧模型，用以预测直喷式柴油机燃烧过程和有害物排放量．该模型将燃烧室划分成许多个燃烧小区，每一个燃烧小区包含了燃油破碎、液滴蒸发吸热、空气卷入、混合气燃烧等过程．该模型的预测能力和精度得到了实验验证． Based on the phenomenological description of direct injection diesel injection combustion process, a quasi-dimensional multi-zone diesel combustion model was established to predict the combustion process and the emission of harmful substances in direct injection diesel engines. The model divides the combustion chamber into many combustion cells. Each combustion cell contains the process of fuel crushing, droplet evaporation and endothermic, air entrainment and mixture combustion. The model’s predictive ability and accuracy have been experimentally verified.
