摘　　要：目前对城市中行驶的重型载货车辆研究较少,导致难以把握其排放情况以及对城市污染的影响程度。文中提出了一种针对重型载货车辆在载重、工况等多种运行条件下排放量的采集与分析方法。以便携式车载尾气检测系统(PEMS)为手段,对国Ⅴ标准的福田柴油车处于空载、四分之一载重、半载重情况下,在市区、高速路、市郊等区域行进状态下采集实时排放量,并对排放率和排放因子进行分析。研究结果表明:污染物的排放率随机动车比功率(VSP)增大逐渐增加且在20kW/t时开始减少,速度与排放因子成反比,CO_(2)、NO_(x)、HC的排放因子与载重量呈正相关,CO排放因子与载重量呈负相关,加速时的排放因子比减速时大。研究成果对城市污染管理具有很好的实际应用价值。At present, there is little research on the heavy-duty truck driving in the city, which makes it difficult to grasp its emission and the impact on urban pollution.The paper proposes a method for collecting and analyzing the emissions of heavy-duty trucks under various operating conditions such as load and working conditions.The Portable Emission Measurement System(PEMS) was used to collect the real-time emission of China Ⅴ emission standards Futian diesel vehicles in urban, highway and suburban areas with no-load, 1/4-load and 1/2-load.Through the analysis of emission rate and emission factor, the results show that the emission rate of pollutants gradually increases with the increase of Vehicle Specific Power(VSP) and begins to decrease at 20kW/t, the speed is inversely proportional to the emission factor, the emission factors of CO_(2),NO_(x) and HC are positively correlated with the load, the emission factor of CO is negatively correlated with the load, and the emission factor at acceleration is greater than that at deceleration.The research has good practical application value for urban pollution management.
