Title: Experimental Research on Fixed Engine Speed Switching of Sequential Turbocharging System with Two Unequal Size Turbochargers for a Vehiclular Diesel Engine
Abstract: An experiment of sequential turbocharging(STC) system with two unequal size turbochargers was conducted on a vehiclular diesel engine.The full-load performance of the diesel engine was measured when the engine was equipped with a small turbocharger,with a big turbocharger,and with both a small turbocharger and a big turbocharger respectively.Two fixed engine speeds for the STC system switching were determined,and the switching experiments of the STC system were performed.It is found that the up and down switching speeds between big turbocharger and small turbocharger are 1380r/min and 1335r/min respectively.And the up and down switching speeds between big turbocharger and two turbochargers are 1970r/min and 1955r/min.The reliabilities of the switching speeds were validated by experiments.
