中文摘要	As internal-combustion engine power density has increased, turbocharger with high pressure ratio is required. With a Fully three-dimension CFD technology, a transonic centrifugal compressor with pressure ratio 4. 0 for vehicle was designed and also applied to micro gas turbine. The design methods and principle of transonic centrifugal compressor were analyzed. The engine-matching test shows that, the performance of the engine improved significantly with the new designed compressor as compared to the prototype compressor. The engine fuel consumption was reduced by 4.1 g/kW ldr h and the inlet temperature of turbine was decreased by 35 K.
