Summary:

Diesel vehicle buyers in Europe are now able to select from a wide range of desirable products with excellent performance and levels of refinement competitive with gasoline engine products. However, the trend towards higher ratings and increased low speed torque appears to have resulted in increased levels of turbocharger generated flow or whoosh' noise.This paper discusses the phenomenon of turbocharger whoosh and its impact on powertrain [1] and vehicle level NVH [2] focusing on:Case studies are drawn from a range of relevant powertrain NVH projects to illustrate the turbocharger whoosh noise development process.The paper includes an insight to the future development of predictive tools for the whoosh noise phenomenon
