摘　　要：随着中国国民经济的不断发展,人民基本生活水平日渐提升,居民机动车保有量上升随之而来的便是机动车尾气污染物的排放量不断增加。机动车尾气的检测技术成为了目前热门的研究。本文简述了机动车尾气中污染物不同成分的危害,详细阐述了目前主要的机动车尾气检测技术,包括遥感检测技术、车载式尾气检测技术、自由加速检测技术、双怠速法和简易工况法。分析了每种方法的原理与方法,总结了每种方法的优点与缺点。本文最后对机动车尾气检测技术提出了一些要求并展望了我国尾气检测技术的未来。With the continuous development of China’s national economy, the basic living standards of the people are gradually improving, and the increase in the number of residents’ motor vehicles is followed by the continuous increase in the emission of motor vehicle exhaust pollutants. The detection technology of motor vehicle exhaust has become a hot research at present. This paper describes the hazards of different components of pollutants in motor vehicle exhaust, and introduces the main motor vehicle exhaust detection technologies, including remote sensing detection technology, portable emission measurement system, free acceleration detection technology, double idle state method, short driving condition method. This paper analyzes the principles and methods of each method, and summarizes the advantages and disadvantages of each method. At the end of this paper, some requirements are put forward for the detection technology of motor vehicle exhaust and the prospects of the detection technology of my country’s exhaust gas are prospected.
