摘　　要：除行驶里程外,其他一些因素也会导致在用车辆排放特性变差.本文分析了影响车辆排放特性的因素并采取必要措施对其进行控制.对注册日期相近但使用工况不同的在用车,利用实验获取排放特性的有关数据,并利用数理统计及灰色系统理论进行分析研究.结果显示,在各影响因素中,行驶里程、维护保养、驾驶习惯等是排放特性的重要影响因素,而且长期不使用或一般在市内行驶的在用车也会导致其排放特性变差.该研究为正确使用车辆,使在用车的排放特性在使用周期内始终保持其应有的水平,减少排放污染提供了实验和理论依据.In addition to the mileage, other factors can also lead to variations in emission characteristics of the in-use vehicle. This paper analyzes the factors affecting vehicle emissions characteristics and take the necessary measures to control them. Based on the data of experiment for emission characteristics, and by using mathemati-cal statistics and grey system theory, an analysis is made of the in-use vehicles of the similar registration dates but in different operating conditions. Results show that of all the factors, mileage, maintenance, and driving hab- its are important factors affecting the emission characteristics, and not being in use for a long time or generally the in-use vehicle in the city can also lead to variations in the emission characteristics. The research provides the experimental and theoretical basis for using the vehicle appropriately, making emission characteristics of the in-use vehicle consistently keep their due levels, and reducing exhaust emissions.
