摘要
在用机动车排气定期检验是要求在用机动车在规定的检验期限进行排气污染检验，通过排气污染定期检验，发现排气超标的车辆，要求按规定进行维修并复检合格。分析广州市三年来实施情况，发现通过排气污染定期检验可筛选14．5％的排气超标车辆，通过修复，超标车辆可减少80％～90％污染物的排放，从而取得了较好的环保效益和社会效益。
Regular inspection and compulsory maintenance system of motor vehicles exhaust pollution （I/M system for short） was a management system of motor vehicle exhaust pollution control which originated in the United States. Regularly inspection of motor vehicle exhaust pollution was used to find vehicles of which exhaust was excessive. Those vehicles were obliged to repair and must pass the re-examination. I/M system in Guangzhou was launched in 2011. Analysis of the implementation in Guangzhou for three years found that 14.5% exhaust excessive vehicles can be screened by the implementation of I/M system. Repairing them can reduce 80% to 90% emission of pol- lutants. In addition, the implementation of I/M system can help to find out the cause of excessive exhaust and major repair items.
