摘要
由于柴油机的燃烧光强不能等同于放热率,而且燃烧光强的形成机理也不够清楚,采用线性的方法难以求得两者之间的转换模型。基于BP神经网络,建立了柴油机的燃烧光强与放热率之间的非线性关系,研究了由燃烧光强重构放热率的神经网络方法。
The combustion light intensity wave and the rate of heat release of diesel are much different, while the combustion luminous mechanism of diesel spray has not been discovered, so the transforming model of them couldn't be obtained by linear method. Based on the BP neural network, non-linear relation between the combustion light intensity wave and the rate of heat release was set up, the rate of heat release of diesel engine was reconstructed by processing the combustion light intensity wave precisely.
