Modeling of AD pump fuel injection process

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.
