摘　　要：采用VMAS排放检测系统作为实验平台,在同一辆实验车上换装不同磨损程度的轮胎进行排放检测。实验结果表明,随着在用车使用的时间增长,轮胎的磨损程度也随之增大,轮胎磨损后导致了轮胎与路面间摩擦力的显著降低,影响到车辆的动力性、经济性和牵引性能,对汽车的排放有直接的影响,特别是在变工况下影响尤为明显。通过实验,找出了轮胎磨损程度与汽车排放特性之间的关系,为控制在用车排放污染物提供了实验依据。By using the VMAS emission detection system as the experiment platform,we can reload tyres with different wear degrees to implement emission detection. As the experiment results show, the wear degree of the tyre increases with the time growth of the vehicle in use, which results in that the friction force between the tyre and the road surface is significantly decreaced. As a result, the vehicle＇s performance, economy and traction performance are influenced,and there is also a direct influence on the vehicle emissions, especially in variable conditons. The study attempts to find out the relationship between the wear degree of the tyre and vehicle emission characteristics, which can provide an experimental evidence for controlling the emission polution of the in-use vehicle.
