| Abstract: | In this paper, the symbolic series bar chart and Shannon entropy are introduced based on the symbolic time series analysis method. And the same time, the ealeulational program of Shannon data is gave. Chose the gasoline engine of the BN492Q and cs492Q to experimentize ,used the Shannon to analyze the experiment data. The result validate that Shannon entropy of the symbolic time series analysis method suit for the Evaluating Parameters of the gasoline engine on The Transient Emissions of Spark-Ignited Engines. |
