文中对汽油机瞬态排放测量的必要性以及国内外发展现状进行了较为详细的介绍,根据国内发动机实验室的具体情况给出了一种利用稳态发动机试验台进行瞬态排放测试的方法。进而提出了可以基于符号时间序列分析的方法对汽油机瞬态排放信号进行分析,获得瞬态排放的特征。
In this paper, the necessity of transient emission measurement of gasoline engine and the development status at home and abroad are introduced in detail. According to the specific situation of engine laboratory in our country, a method of transient emission test using steady state engine test bench is given. Furthermore, the transient emission signal of gasoline engine can be analyzed based on symbol time series analysis to obtain the characteristics of transient emissions.
