一种车载排放测试系统的应用研究

Research on Application of a Vehicle Portable Emission Measurement System

针对汽车实际行驶排放的试验与评价,以车载排放测试系统研究为基础,以排放法规为指导,采用移动平均窗口法,开发了车载排放试验数据处理软件,解决了排放污染物的计算与排放性能评价等问题,并在此基础上开展了车载排放道路试验,从而建立了研究汽车在实际道路行驶条件下排放特性的技术手段。

For the testing and evaluation of real driving emission （RDE）, on the basis of portable emission measurement system （PEMS） technology research and the guidance of emission regulations, by using the moving average window method, a software was developed to calculate emissions and evaluate emission performance. The vehicle on-board emission test was carried out, the technology for studying vehicle emission characteristics in real road working condition was established.
