南京市机动车污染物减排因素分析

以南京市机动车排污监控系统的实时检测数据为基础,简述了南京市机动车减排效果,在“十二五”期间南京市机动车保有量增长71.8%的背景下,实现了污染物排放量削减18.8%,单车平均排放CO、HC、NOx较3年前分别下降了33%,31%和36%;排放标准和使用年限二因素方差分析表明,其对NOx、CO和HC排放值的影响由大到小排序均为：油品质量〉排放标准〉使用年限。提出,进一步提升油品质量至关重要。

Factor Analysis of Motor Vehicle Emissions of Pollutants in Nanjing City

Based on the real time data monitoring system of motor vehicle emission in Nanjing city.This paper briefly describes the effect of Nanjing automobile emission reduction .In the "Twelfth Five Year Plan" period, Nanjing City motor vehicle retains the 71.8% growth, implementing the pollutant emissions reductions by 18.8 and average emissions of CO, HC, single NOx fell by 33%, 31% and 36% compared with 3 years ago; emission standard and analysis of variance showed its effect on NOx, CO and HC emission value from big to small order are: The quality of oil > emission standard > Life. Thus it is very important to enhance the quality of oil.
