New Developments in Wastegated Passenger Car Turbocharger Aerodynamics

Passenger Car OEM's are always interested in new ways to improve vehicle transient response with turbocharged engines. Increasingly, there is also demand for smaller turbocharger package size to fit within ever decreasing engine compartment space. Component weight reduction becomes more critical as emission requirements stiffen and pressure to reduce cost is constant.

These four critical requirements for the future passenger car turbocharger are all addressed at once by Garrett's development of a new family of very compact high flow compressors and turbines for wastegated passenger car application.
