基于VMAS系统的在用车排放特性研究

Based VMAS system on the in-use vehicle emission characteristics study

利用VMAS排放检测系统作为实验平台,对在用车排放因子进行检测,并用灰色理论对数据进行分析研究,找到了影响在用车排放特性的因素。研究结果表明,在用车的行驶里程、维护保养对其排放特性有较大的影响,随着行驶里程的增加,其排放特性也随之变差。

How to effectively control of in-use vehicle emission is has always been very concern of the people .Through the use of VMAS emission test system as experiment platform to test the in-use vehicle emis-sion factor and the grey theory to research and analyze data , find the influencing factors of in-use vehicle emis-sion characteristics .Research results show that the in-use vehicle mileage , the maintenance of the properties have great influence on its emissions , is obtained with the increase of mileage its emission properties became worse .The research method is simple , practical and scientific , has characteristic of in-use vehicle emission research short cycle , low cost advantages .To use this method to carry out in-use vehicle emission characteris-tics research provides theoretical and experimental basis to control emissions .
