摘　　要：针对目前的机动车排放研究对随着使用年限和行驶里程变化研究较少的问题,选择轻型电喷汽油车作为研究对象,利用机动车尾气监测中心所测得的机动车尾气测试数据,研究了轻型电喷汽油车的排放情况随使用年限和行驶里程的变化关系,采用回归分析的方法,建立了轻型汽车主要排放污染物CO、HC的排放浓度与使用年限和行驶里程的对数关系模型。结论表明,轻型车的排放浓度随着使用年限和行驶里程的增加呈现不断增加趋势,从投入使用到使用年限达到3年或行驶里程达到9万km这一阶段,排放劣化较迅速,此后排放劣化的程度明显减缓。研究结论对于定量评价城市机动车排放总量以及制定相应的排放控制策略,可以提供理论支持。There are fewer study of the relation between the useful life, total mileage and vehicle emissions, light-duty EFI gasoline vehicle was chose as the research object, the measured vehicle emissions test data can be got from motor vehicle exhaust monitoring center, analysis of the relationship between light-duty EFI gasoline vehi- cles emissions and useful life , total mileage, using logarithmic regression to conduct the model of CO, HC emission concentrations and useful life, total mileage. Concluded that the light-duty EFI gasoline vehicle emissions increase with the useful life and total mileage, the emission deterioration speed is more quickly from operational to the life of 3 years or 90,000 km mileage,since emission deterioration speed has slowed down significantly. The research can be used for quantitative evaluation of urban motor vehicle emissions and provide theoretical support for developing appropriate emission control strategy.
