摘要
车载尾气检测技术的出现和发展为机动车尾气的相关研究提供了一种较为准确、便捷、实时反映城市路网排放的测试方法。本文详细介绍了车载尾气检测技术的发展历程和原理,综述了该技术在行驶周期开发、尾气排放特性和规律研究、建立机动车尾气排放数据库和建立城市路网排放清单等领域的应用现状,并通过比较该技术在国内、外的应用差距,提出了在绿色交通领域充分利用该技术进行机动车污染评价与控制的合理建议。
The emerging and development of portable emission measurement system（PEMS） technologies provide the test of vehicle emissions on urban road network in an accurate and convenient way with real-time response.This paper describes the development process and theory of PEMS and provides an overview about the application of PEMS in the areas of developing vehicle driving cycles,analyzing emission characteristics,and establishing vehicle emission database and urban road emission inventory.In addition,the gaps of PEMS application are compared and some valuable suggestions are put forward for the full use of PEMS to control vehicle emissions in green transportation.
