【Abstract】 Based on a vast amount of actual measured CO emission data of car engines in use on idle condition, this paper carries out the statistical analysis, reveals the optimum fitting distributions and the distribution parameters of car engine CO emission on idle conditon, at the same time, establishes corresponding CO emission models which include the distribution density functions and the distribution functions. The research of this paper will play a very important part in calculating the CO emission data of car engines on idle condition accurately, evaluating the pollution caused by car engines CO emission to atmospheric environment of cities and their suburbs correctly, and revising vehicle emission control laws and regulations.更多还原
