Equilibrium Algorithm Research of Each Cylinder for Common-Rail Diesel Based on Self-Adaptive Fuzzy Control

摘要

Many factors will influence injector's performance, and correlation among them is very complicated after experiments of Electronic-Controlled Injector (ECI) were carried out. Equilibrium algorithm based on Self-Adaptive Fuzzy Control (SAFC) was put forward to ensure consistency of injectors and remedy shortages of static compensation algorithm. Model of Common-Rail System (CRS) was created under MATLAB/SIMULINK. It was shown by experiment results SAFC algorithm had good effects on reducing speed unevenness of each cylinder, and it was found that effect for reducing unevenness when speed was over 1600 rpm was not very remarkable compared with below 1000 rpm for the diesel used for experiments.
