| Passive bypass valve |
Within the air intake pipe exiting the turbochargers is a passive bypass valve. The purpose of this valve is to prevent intake air recirculating through the fixed geometry turbocharger when in Variable Geometry Turbine (VGT) mode only or series mode. If no valve was installed compressed air would recirculate back to the High Pressure (HP) compressor inlet. The turbocharger intake air pipes are 2 different diameters, the smaller pipe exits the VGT and the larger pipe exits the fixed geometry turbocharger. The larger diameter pipe contains a spring loaded passive bypass valve which acts like a one way valve for air exiting the fixed geometry turbocharger.
