VSP Bin作为近年来较为成熟的机动车排放模型参数,并未在烟雾排放评估中应用。为了将VSP变量引入到柴油车在隧道内的烟雾排放量评估模型中,在研究VSP计算模型及其参数标定的基础上,探讨了基于VSP分布的柴油车烟雾排放特性,并应用聚类分析法对VSP进行分区数据处理。结果表明,单纯通过VSP分析烟雾排放特性,数据离散性相当明显,然而经过聚类数据处理后,VSP Bin与柴油车烟雾排放量之间的关系呈现良好的线性相关,验证了VSP Bin比功率分区作为烟雾排放量预测参数的可行性。
As a mature model of vehicle emission model in recent years, VSP Bin has not been applied in the assessment of smoke emission. In order to introduce the VSP variable into the model of smoke emission assessment of diesel vehicles in the tunnel, based on the study of VSP calculation model and parameter calibration, the smoke emission characteristics of diesel vehicles based on VSP distribution are discussed and the cluster analysis method VSP partition data processing. The results show that the VSP Bin has a good linear relationship with the diesel vehicle smoke emission after the VSP Bin is analyzed by the VSP. However, the VSP Bin is more accurate than the power partition Feasibility of predicting smoke emissions.
