摘要
为了缩短柱塞式燃油喷射系统产品研制开发周期,提出了引入修正系数的AD型喷油泵系统喷射过程理论模型计算机建模的研究方法.通过计算机建模、优化求解修正系数以及对修正系数优化结果的线性回归分析,建立了修正系数的线性回归方程,完成了该系统修正后的喷射过程理论模型建模.仿真预测与检验表明,其预测结果与实测值吻合,可应用于诸如P7型等柱塞式喷油泵系统喷射过程的理论模型研究.
In order to reduce some experiments and cut down the consumption of raw materials needed for modeling of fuel injection process, a theoretical method based on modeling by computer is proposed for research on AD pump fuel injection system. A revised theoretical model for AD type pump fuel injection system is established and revised coefficients have been established through multi-target optimization. The optimized coefficients are used to establish the coefficients' equations. The calculating simulation and examination is implemented by the revised theoretical modeling for AD pump fuel injection system. The results coincide with experimental results. The theoretical research based on the revised model can be used to predict the performance of other types of fuel injection systems, such as P7 type.
