面向动力需求的汽油机性能与油品组分关联性分析
Correlation analysis of gasoline engine performance and oil product composition based on power demands
为探究影响内燃机动力性能的因素和影响途径，基于全参数可控特种发动机试验平台开展了稳态工况下的发动机性能试验，提出基于BP神经网络的发动机动力性能参数关联性研究。确定以燃烧相位、燃烧持续期、累计放热量、平均指示压力等典型的燃烧过程参数为中间层因变量，将指标进行归一化处理，建立基于BP神经网络的输入层（发动机控制参数、油品）-中间层（燃烧过程参数）-输出层（发动机输出功率）的关联性分析模型，以相关系数评价各指标参数间的相关性。研究表明，与发动机性能相…查看全部>>
In order to explore the factors and ways of affecting the dynamic performance of internal combustion engines, the engine performance tests under steady-state conditions were carried out based on a full-parameter controllable special engine test platform, and a correlation study of engine dynamic performance parameters based on BP neural network was proposed. Determine the typical combustion process parameters such as ignition advance angle, air-fuel ratio, c…查看全部>>
