【摘要】 通过实测直喷式柴油机燃烧不同十六烷值柴油时的缸内压力示功图 ,以此计算出相应的燃烧放热规律。通过分析影响放热规律的有关参数 ,确定了对几项因子通过试验匹配来进行直喷式柴油机燃用低十六烷值柴油的初步研究。以试验研究为基础 ,利用神经网络的非线性映射性能得出了燃用低十六烷值柴油时几个参数的调整方案。更多还原

【Abstract】 According to its indicated pressure diagrams measured under the condition of burning diesel fuels with different cetane number in D.I. diesel engine,this paper calculates corresponding heat release rates.By analyzing related parameters affecting heat release rates,several parameters are determined to be tested for initial study on burning diesel fuel with low cetane number in D.I. diesel engine.Based on experimental study and employing the nonlinear mapping capacity of neural network,an optimum scheme of several parameters is suggested under the condition of burning diesel fuel with low cetane number.更多还原
