摘要
瞬态排放间接检测是对汽油机在汽车加速滑行组合、节气门加速开启关闭等瞬态工况下进行法规性检测、获得其排放状况的基本手段之一.本文进行了汽油机瞬态排放间接检测的实践:研制了汽油机瞬态排放试验研究所用的节气门瞬态控制器,通过对比试验获得五组分排放分析仪瞬态检测性能,采用符号时间序列的单缸Shan-non熵作为瞬态排放特征参数,构建了汽油机瞬态排放间接检测平台.
The indirect inspection of transient emission is one of the basic measurements to achieve the exhaust situation of gasoline engine by law inspection in the transient conditions such as vehicle acceleration-coasting or carburetor accelerating turn on-off. In this paper the practice of indirect inspection of transient emission of gasoline engine is carried out; a transient throttle control device for transient emission research of gasoline engine is developed; the capability of transient inspecting of five components exhaust analyzer is obtained by the parallel experiment; the single cylinder Shannon entropy of symbolic time series is offered as characteristic parameters of transient emission; the indirectly inspecting platform of gasoline engine transient emission is established.
