用多区模型预测直喷式柴油机燃烧过程和排放

以直喷式柴油机喷油燃烧过程现象学描述的基础，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。

Prediction of DI Diesel Engine Combustion and Emission with Multi-Zone Model

A model for the prediction of DI diesel engines has been developed. This model is a quasi-dimensional phenomenological multi-zone combustion model. It takes into consideration, on a zonel basis, details of fuel spray formation, droplet evaporation,air-fuel mixing and combustion. The predictive capability of the model has been proved by experiments.
