Specifiion

Description

Variable-geometry or variable-nozzle turbochargers use moveable vanes to adjust the air-flow to the turbine, imitating a turbocharger of the optimal size throughout the power curve.[36][37] The vanes are placed just in front of the turbine wheel like a set of slightly overlapping walls. Their angle is adjusted by an actuator to block or increase air flow to the turbine.[37][38] This variability maintains a comparable exhaust velocity and back pressure throughout the engine's rev range. The result is that the turbocharger improves fuel efficiency without a noticeable level of turbocharger lag. A VGT Turbocharger can also work as an exhaust brake by closing off the exhaust entirely, for example in the RAM HD Pickup Trucks equipped with the Cummins Diesel Engine.

Characteristic

1.The turbine, which is almost always a radial inflow turbine (but in large Diesel engines is almost always a single-stage axial inflow turbine)

2.The compressor, which is almost always a centrifugal compressor

3.The center housing/hub rotating assembly
