Fuel Common Rail Injection System of RT-Flex Marine Intelligent Diesel Engine and Its Simulation Dynamic Model

摘要

Based on comprehensively analyzing the whole structure and its working performance of RT-Flex marine intelligence diesel engine and entirely mastering this kind of engine fuel common rail injection system's composition, working principle, taking 7RT-Flex60C as simulation object, the mathematical models of this system's composing part are designed, by using Matlab/Simulink simulation tool, fuel common rail injection system simulation model is set up, then comparing with the simulation data with rack test data, the accuracy and effectiveness of the model are test and verified. The built up model provides a convenient and practical method for design, optimizing and simulation of fuel common rail injection system.
