Seventy-five diesel vehicles were measured in China using a portable emissions measurement system (PEMS). Particular matter (PM) emission factors and gaseous emission factors for Euro 0 (E0), Euro 1 (E1), Euro 2 (E2), and Euro 3 (E3) trucks were obtained under highway, urban, and rural driving conditions. Vehicle emission regulations in China have successfully reduced carbon monoxide (CO), hydrocarbons (HC) and PM by 62, 56, and 72% on average. Most of the emission reductions were achieved when the control technology went from E0 to E1 in Xi'an, and E2 to E3 in Beijing, which resulted in PM reductions of 79% associated with highway driving and 60% associated with urban or rural driving. Emission levels of oxides of nitrogen (NO(X)) were not improved from previous emission control steps. Compared with Xi'an, the emission rate is lower in Beijing, which is strong evidence of the effectiveness of the present comprehensive emission control strategy in Beijing. Emissions were grouped into driving bins that corresponded to the energy demand placed on the vehicles. By using this binning approach, it was found that E3 trucks were successfully controlling the high emission rates in aggressive driving bins, which led to the low average emission for E3 trucks.
在中国，使用便携式排放测量系统 (PEMS) 对 75 辆柴油车进行了测量。在高速公路、城市和农村行驶条件下，获得了欧 0 (E0)、欧 1 (E1)、欧 2 (E2) 和欧 3 (E3) 卡车的颗粒物 (PM) 排放因子和气体排放因子。中国的车辆排放标准成功地将一氧化碳 (CO)、碳氢化合物 (HC) 和 PM 的平均排放量减少了 62%、56%和 72%。在西安，控制技术从 E0 升级到 E1，在北京，从 E2 升级到 E3 时，大部分减排效果最为显著，这导致与高速公路行驶相关的 PM 减排了 79%，与城市或农村行驶相关的 PM 减排了 60%。氮氧化物 (NO(X)) 的排放水平没有从以前的排放控制步骤中得到改善。与西安相比，北京的排放水平较低，这充分证明了北京目前综合排放控制策略的有效性。排放被分组到与车辆能源需求相对应的驾驶箱中。通过使用这种分组方法，发现 E3 卡车成功地控制了激进驾驶箱中的高排放率，从而导致 E3 卡车的平均排放较低。
