| Abstract: | The compressor surge phenomena of a sequentially turbocharged diesel engine,which may appear during the butterfly-valve switch phase,can be prevented effectively by adopting a reasonable switch delay time.Consequently,the transition process of switch will be smoothly.Based on the finite volume method,a computer model for a TBD234V12 marine diesel engine with sequential turbocharging system is established.Through the simulation,this paper analyses the influence of butterfly-valve switch delay time on the ope... |
