摘要
提出了一种基于柴油机示功图数据分析及灰色预测理论的柴油机热力性能预测方法 .该方法从一系列实测示功图压力数据中还原燃烧规律 ,提取燃烧规律曲线的特征值 ,并采用灰色预测理论来预测未来的燃烧规律 ,代入柴油机工作过程计算程序中得到其各热力参数 ,具有一定的理论及实用价值 .
In this paper, a new prediction method of diesel engine′s thermodynamic performance based on gray theory is discussed. The rate of heat release is restored from a series of indicator diagrams which vary with a certain law. By using gray theory, the next rate of heat release can be predicted . The new rate of heat release can be used to get the diesel engine thermodynamic performance which we want.
