在用车排放测量技术分析

Analysis on Emission Measuring Technique for In-use Vehicle

控制汽车排放污染主要分成新车核准和在用车阶段。随着我国汽车排放标准的逐步加严，新生产车需要满足越来越严格的排放法规，以满足国家有关部门管理上的准入要求。2005年4月15日国家环保总局和国家质量监督检验检疫总局联合发布了《轻型汽车污染物排放限值及测量方法（中国Ⅲ、Ⅳ阶段）》，并将在2007年7月1日于全国范围内实施，其中OBD顺延一年；经国务院批准，

Following the tightening of emission regulations and improvements of control techniques,idle speed method no longer satisfies the requirements for testing vehicles with low emission.The several test methods for simple driving conditions introduced in this paper have corresponding merits and shortcomings,which should be implemented with appropriate test methods,based on local atmospheric pollution and total number of automobile,especially in areas with high automobile density and severe pollution.Inspection for in-use vehicles should also be enforced.
