摘要
应用美国Sensors公司生产的SEMTECH-DS车载排放测试仪,通过双怠速法、ASM稳态工况法及道路工况法对同一品牌不同行驶里程的城市出租车进行了排放特性的研究,比较了不同测试方法对排放测试结果的影响,并分析了车辆行驶里程与排放特性的关系。结果表明,双怠速工况下排放污染物超标的行驶里程与ASM工况基本相似;道路工况对汽车污染物排放影响显著;3种测试方法下的HC排放污染物均随行驶里程的增加而升高。
The paper makes a research on emission characteristics of the same brand city tax1 with different mileage based on two-speed idle exhaust emission test, ASM steady state mode condition and road condition with SEMTECH-DS from Sensor company, compares the influences on the test results with different test methods and analyzes the relationship between emission characteristics and vehicle mileage. The results show that the mileage in two-speed idle condition in which emission pollutant exceeds standard is similar to that in ASM condition： road conditions affect vehicle pollutant emission greatly; HC pollutant in three test methods increases with mileages.
