【摘要】 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。更多还原

【Abstract】 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 emission factor and the grey theory to research and analyze data,find the influencing factors of in-use vehicle emission 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 characteristics research provides theoretical and experimental basis to control emissions.更多还原
