摘要
介绍了符号时间序列分析中的直方图、Shannon熵和高阶矩等,结合排放的体积百分数,对TOYOTA2500汽油机瞬态排放中的CO进行了分析.在节气门匀速变化时和匀加速变化时,比较速度值不同时的瞬态排放质量.
The symbolic series bar chart, Shannon entropy and high rank square are introduced based on the symbolic time series analysis method., and combined with the percent of volume. This method is used to analyse the CO of emission of TOYOTA2500 gas engine in transient condition. Under the circumstance of uniform velocity and uniform increase velocity, we respectively compare the burning degree of transience of different velocity.
