基于Shannon熵的汽油汽车瞬态排放评价参数
The Evaluating Parameters on the Transient Exhaust of Gasoline Vehicle Based on Shannon Entropy
【摘要】 对符号时间序列方法进行了说明,使用单缸Shannon熵对3种汽油汽车瞬态排放中的HC和CO进行分析,结合排放值,在它们之间进行对比分析,提出新的评价参数,进而可以评价它们的燃烧状况。
【Abstract】 In this paper,Symbolic Time series analysis is explained.The Shannon entropy of single cylinder is used to analyse the CO and HC of emission of three gasoline vehicles in transient condition,and combined with the emission value.Through compared them with each other,we elicit the new evaluating parameters to evaluate their status of burning.
