摘　　要：提出一种基于车载式的汽车尾气排放测量新方法,该方法按照国家标准规定的工况在实际路面上进行汽车排气物检测,使用单片微机实时记录各排气污染物的相关参数,通过串行通信传送到PC机计算出瞬时排放量,最后进行数值积分计算得到整个过程的总排放量。A new measurement method for vehicle exhaust emission based on the on-board test is presented in this paper. While the vehicle is running on the road in accordance with the test mode specifications in the national standards, the microcontroller makes a real-time record of each parameter of the exhaust pollutants and then sends the data to PC by serial communication to calculate the instantaneous values of each pollutant.By means of the numerical integral method, the total emission amount was got.
