VGT Features
• The turbocharger for the 6.0L Power Stroke
engine is designed to provide boost control
at low and high speeds for improved throttle
response.
• The Variable Geometry Turbocharger (VGT)
is electronically controlled and hydraulically
actuated.
• The VGT may also be referred to as EVRT.
• When the vanes of the turbocharger are
closed, the engine will have a higher
exhaust back pressure and create more
heat which will in turn warm the engine
faster in cold ambient conditions.
VGT Compressor
• The compressor on the VGT is similar to the
compressor on a conventional turbocharger.
• The compressor wheel is connected to the
turbine via a common shaft.
VGT Turbine
• The VGT uses a turbine wheel that is
similar to a conventional turbocharger but
the turbine housing has changed.
• The turbine housing contains vanes that
control the effective size of the housing.
These vanes are hydraulically actuated and
electronically controlled.
