4. OPERATING PRINCIPLES
The E-VGT is designed to get more improved engine power in all ranges by controlling the turbine
as follows:
1) How it Works at Low Speed
Normal turbocharger cannot get the turbo effect because the amount of exhaust gas is not
enough and the flow speed is slow in a low speed zone, but VGT allows the flow passage of
exhaust to narrow, resulting in increasing the flow speed of exhaust gas and running the turbine
quickly and powerfully.
Therefore, as VGT can intake more air than normal turbocharger, it can give the benefit of the
increased output even in a low speed zone.
Turbocharger lag
The turbocharger is at idle speed when there is no load or it is in the normal driving condition.
During this period, the amount of exhaust gas passing through the turbine is not enough to turn
the compressor wheel (impeller) fast. Therefore, the intake air is not compressed as needed.
Because of this, it takes time for turbocharger to supply the additional power after the
accelerator pedal is depressed. This is called "turbocharger lag".Basic principle at low speed
At low speed, it utilizes the principle of
venturi.
For example, when air flows through the
venturi tube, the flow speed is faster and the
pressure is lower at the point "A". In this case,
if the inner
diameter of venturi is more narrowed, the flow
speed is so much faster (refer to the
equation). ※
