Abstract

7RT-flex 60C diesel engine is selected as the research object to analyze the characteristics of common rail system. Based on the continuity equation and the motion equation of the fluid mechanics, the mathematical model with blocks is established on servo pumps, collector, common rail pipe of servo oil and vent control module, etc. All the mathematical models are calculated by MATLAB/Simulink to achieve the dynamic simulation and parameter analysis on the collector and servo oil common rail pressure, servo pump plunger stroke, pressure and flow rate of plunger hole, etc. Comparison of simulation results of curve and data with the basic characteristics of actual servo oil common rail system verifies the correctness of the proposed model.
