摘要
为了分析CNG汽车道路排放的微观特性,采用车载排放测试系统,并选取市区主要道路为试验路段进行了实车道路试验。通过试验获取典型车辆的排放数据及行驶状态,分析车辆在实际行驶中的排放特性,为预测不同交通状态下CNG汽车的排放特性和区域排放清单建立提供参考。
In order to analyze the microscopic emission characteristics of CNG vehicles,the on-board vehicle emission test system was used,and the main urban roads were selected as the test sections,and the real vehicle road test was carried out.The typical vehicle emission data and driving state were obtained through tests,and the emission characteristics of vehicles in actual traffic were analyzed.It provides a reference for predicting the emission characteristics of CNG vehicles under different traffic conditions.
