摘要
为了适应欧Ⅲ排放法规的需要,针对西安市区城市道路上正常行驶汽车的工况及排放情况进行研究,通过采用GPS测速系统和IPEXD便携式排放测量仪,快速、准确的获取汽车正常行驶过程中的即时速度及瞬间排放污染物等客观数据,进而具体分析汽车在城市道路上的行驶工况及排放情况,最终计算得出西安市城市道路上行驶汽车的相应工况、即时速度与瞬间排放之间的关系。其中,本文主要研究以汽油为燃料的车辆在城市道路条件下行驶时尾气排放中的HC、CO、NOX三种污染物,客观分析并确定日常城市道路条件下汽车行驶工况对其排放的相关影响。
In order to adapt to the needs of the Euro III emission regulations, the article makes the actual traffic of vehicles of Xi＇ an city for the object of study, making use of IPEX D emission measurement , GPS system to gain the actual speed of traffic, the data of pollution emissions. On the basis the article ana- lyzes the driving cycle and the actual situation of pollution emissions, at the same time, further studies the relationship between driving cycle, speed and emissions. The article takes CO, HC, NOX pollutants as the main subjects, analyzing how the driving cycle on the actual roads affects emissions
