Abstract

Wartsila RT-flex 60C diesel engine is selected as the object to research pressure control of fuel common rail system, building the system simulation model, and analyzing main factors influencing rail pressure in the system. it was concluded that they were diesel engine speed, load. In the process of MATLAB/Simulink simulation, the rail pressure control logic was designed by adopting maps with the two factors as independent variables to get theory feedforward quantity of fuel rack, feedback quantity of fuel rack is obtained by fuzzy PID control. The simulation experiments show that the improved control method reduces the rail pressure fluctuation, at the same time the overshoot volume of dynamic rail pressure control is greatly reduced, response velocity quickened. The control method has been used in a Marine simulator.
