To improve the vehicle diesel engine performance at part-load operation, experiments on sequential turbocharging system used in a vehicle diesel engine are investigated in this paper. The brake specific fuel consumption and smoke emission of diesel engine are measured in four schemes: with the based turbocharger, with a small turbocharger, with a big turbocharger, with both small and big turbochargers. Then, a new turbocharging method named three-phase sequential turbocharging system with two unequal size turbochargers is presented by analyzing and comparing the experimental results. The experiment on a vehicle diesel engine with three-phase sequential turbocharging system shows that the brake specific fuel consumption and the smoke emission are reduced observably in complete engine speeds range, especially in the low speed operation. Finally, the transient performances of three-phase sequentially turbocharged vehicle diesel engine are analyzed by experiments. The transient experimental results show that in the transient accelerating operation the smoke emission of the diesel engine with the three-phase sequential turbocharging system is lower than that with conventional turbocharging system.
