摘　　要：为了确定城市道路交叉口的机动车排放影响因素及特点,以长春市内典型的五路交叉口-工农广场为例,采用车载OEM-2100排放测试系统对捷达Gix 1.6L和金杯EFI2.4L两种车型在工农广场交叉口的瞬态排放进行了系统地测试,以NOx、HC和CO三种污染物作为主要研究对象,对比分析了车型运行工况与排放率的关系、不同时段的排放状况比较以及速度、加速度对排放率的影响。In order to determine the influencing factors and characteristics of vehicle emission on urban mad intersection, a typical urban road intersection of Changchun City was selected as an example, and the instantaneous mass emission of Jetta Gix 1.6L car and Jinbin EFI 2.4L bus were tested by using OEM-2100 emission tester. Taken NOx, HC and CO as the main pollutants, the relations between emission rate and driving mode, the emission statuses in different time periods and the influence of speed and acceleration on emission rate were all analyzed and compared.
