| 摘 要： | 为了降低柴油机的NO_X的排放,所设计EGR的系统采用并联的文曲利管对EGR率进行控制。通过建立计算EGR率的数学模型,可以控制废气再循环系统的EGR率,为EGR的设计提供了依据。对文曲利管的工作特点进行了分析,对采用文曲利管的EGR系统进行了分析计算,计算出了典型的EGR系统的文曲利管的相关结构参数。结合试验结果分析了EGR系统对柴油发动机排放的影响,得到了EGR系统能够有效地降低柴油机的NO_X的排放的结论。

| Abstract: | In order to reduce the NO_X emission of the diesel engine,the EGR system is adopted which uses parallel Venturi tube to contrl the rate of EGR control.In the article,through the establishment of a mathematical model of caculating EGR rate and control EGR rate can be analyzed and controlled.The result of the model provides the basis for the design of EGR.The characteristic of Venturi tube is analyzed and the EGR system parameters are analyzed and computed in this article.The size structure of the relevant parameters of the EGR system is calculated.The test result has analyzed the influence of the EGR system which discharges on the diesel engine and the conclusion is drawn that this EGR system can effectively reduce NOx emissions from the diesel engine. |
