摘　　要：随着机动车数量日趋增多,机动车尾气污染问题已引起政府高度重视。为了改善大气环境质量,利用科学先进的尾气检测方法严查高排放车辆已成为必要手段。本文通过阐述稳态工况法检测的工作原理及操作流程,分析了该检测方法具有试验设备充分简化,技术成熟,测量稳定,能识别NOx高排放车辆等优点,但也存在误判率较高,检测精确度较低,与汽车实际行驶工况关联性差,易作弊等不足,基于上述不足,提出改进尾气检测的建议,进而提高机动车科学化、规范化检测水平。With the increasing number of motor vehicles,the problem of vehicle exhaust pollution has aroused high attention from the government.In order to improve the atmospheric environment quality,it has become necessary to use the scientific advanced methods to detect high emission vehicles.Through the elaboration of steady-state gasoline-fuelled vehicles detection principle and operation process,this article analyzes the detection method with advantages of simplifying testing equipment,mature technology,stable measurement,and the recognition of high NOx emissions from vehicles,but there is also some weaknesses of higher misjudgment rate,low detection precision,and poor actual conditions of relevance and of being easy to cheat.Based on the above,the author puts forward Suggestions for the improvement of exhaust gas detection in order to further improve the level of scientific standardized testing of motor vehicles.
