Switching Time Research on Pneumatic Butterfly Valve for Marine Diesel Engine Sequential Turbocharging System

In the paper, we established the physical model of butterfly-valve of diesel engine with sequential turbocharging (STC). And the corresponding mathematic model was built through applying the theory of pneumatic transmission system dynamic. Then simulating the process of butterfly valve switching with the simulation software, Matlab/Simulink, it is concluded that the main factors which influence the switching time of butterfly-valve and the result of simulation was also analyzed. Finally, the test-bench of the butterfly-valve control system was built. And we realize the reliability of the result of simulation through contrasting the results of testing and simulation. The research provided basic theory to knowledge the character of the butterfly-valve control system in-depth.
