在用汽油车尾气超标特征分析及对策研究

The Characteristics Analysis and Countermeasure Research on the In-use Gasoline Vehicle Exhaust Emission Exceeding

机动车尾气排放是机动车污染问题的主要原因。通过对不同基准质量区间和不同行驶里程的在用汽油车排放检测数据的统计分析,发现在用汽油车在不同行驶里程区间的尾气排放超标率有明显不同,同时针对其在不同行驶里程区间尾气排放超标的各自特点,提出了维护、治理、维修等不同方面的对策。

Through statistically analyzing the in-use gasoline vehicle emission test data between different benchmark quality range and different mileage, this paper found the obvious difference of the exhaust emission exceeding rate. For their respective characteristics of exhaust emission exceeding with the range of different mileage, it also put forward the countermeasures of maintenance, management, repair and other aspects.
