直喷式柴油机主燃期量化研究

Quantitative Research on the Main Combustion Period in Direct Injection Diesel Engines

在采集了大量数据的基础上,用本文提出的基于K-L变换的GMDH改进方法建立了柴油机主燃期平均燃烧速率的数学模型.研究结果表明,所建模型具有较好的模型精度和计算稳定性.此种建模方法对柴油机燃烧过程的建模有一定意义.

Based on the collection of many data, a mathematical model of mean combustion rate of the main combustion period (MR) has been established by the revised GMDH approach, which is also proposed in this paper, on the base of K-L shift. The research shows that this model has satisfactory precision and calculation stability. This model is useful to the modeling of the combustion process of diesel engines.
