| Abstract: | In this paper,the research on the effect of variable nozzle turboeharger（VNT）applieation on medium-duty high pressure common rail diesel engine performance and economy was studied. Furthermore fitting with EGR system, to as sess the effect of EGR ratio promotion and emission reduction by VNT.Then,the initial research on the combination control of VNT and EGR was carried out. |
