摘要美国环境保护署（EPA）实施了一项计划，以确定尾气排放的标准和空气中的有毒污染物在使用中，轻型低排放车辆（LEV）。EPA在2002年招募了25辆LEV，并使用联邦测试程序的冷启动城市测功机驾驶时间表在底盘测功机上测量排放。测量的排放量包括受管制的污染物、颗粒物、物种碳氢化合物和羰基化合物。结果提供了一个比较的排放标准和空气中有毒化合物从现实世界的LEV的排放。排放测量表明，部分测试的在用车队超过了标准气体的标准。实时调节和物种碳氢化合物测量表明，大部分排放发生在城市测功机驾驶时间表冷启动部分的初始阶段。总的来说，该研究提供了更新的排放因子数据，为现实世界，在使用中的操作的LEV改进排放建模和移动的源清单的发展。
Abstract The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, light-duty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included regulated pollutants, particulate matter, speciated hydrocarbon compounds, and carbonyl compounds. The results provided a comparison of emissions from real-world LEVs with emission standards for criteria and air-toxic compounds. Emission measurements indicated that a portion of the in-use fleet tested exceeded standards for the criteria gases. Real-time regulated and speciated hydrocarbon measurements demonstrated that the majority of emissions occurred during the initial phases of the cold-start portion of the urban dynamometer driving schedule. Overall, the study provided updated emission factor data for real-world, in-use operation of LEVs for improved emissions modeling and mobile source inventory development.
