周文杰, 程江华, 石磊, et al. Research on Valves Coupling Control in Diesel Engine Sequential Supercharging Switching Process[J]. 2020, 41(5): 70-76. DOI: 10.13949/j.cnki.nrjgc.2020.05.010.
In order to solve the problems of compressor surge and backflow during the switching process of the sequential supercharging system of a diesel engine
a coupled GT Power/Simulink sequential supercharging system simulation model was established and the influence was studied of delayed compressor action during the switching process on the compressor surge and backflow. The simulation results showed that the delayed shutdown of any compressor could avoid the compressor surge
and the delayed startup of any compressor could avoid the reverse flow. Through an appropriate valves coupling control strategy
the fluctuation of boost pressure during the switching process could be reduced by 9.3%~21.6%.
