Fuel Injection Control and Simulation of EFI engine Based on ANFIS

摘要

EFI engine's ECU through a fixed pre-set supply procedures to control fuel injection time, however, the pre-set data can only be reached through a large number of tests. How to attain to pre-set data efficiently and how to dynamically adjust the fuel injection time according to the traffic circumstance are currently the hot issues in Engine Electronic Control Simulation field. In this paper, aiming at the problem of fuel-oil supply control of EFI engine, a hybrid method which combines the fuzzy theory and neural network-Adaptive Network-based Fuzzy Inference System is presented, taking into consideration the characteristics of the EFI engine's structure. The structure, composition and working procedure of the ANFIS system used for fuel-oil supply control of EFI engine are studied and discussed. A simulation result is also given in this paper.
