| Abstract: | Variable nozzle turbocharger(VNT) can improve the low-speed performance and emission of turbocharged diesel engine.Turbine experiment of JK90S turbocharger with rotating vanes was undertaken.The results show that turbine performance can be adjusted effectively.The matching experiment for WD615 diesel engine with VNT was also carried out,and the results were compared with those with constant geometry turbocharger.It can be shown that using VNT,the power and fuel consumption at low speed are all improved. |
