Electronically V ariable Geometry T urbocharger (eVGT)
The electronically V ariable Geometry T urbocharger (eVGT) used the TIER and TIER and The eVGT electronically controlled the Engine Control Unit (ECU).
The eVGT uses a series aerodynamic vanes direct exhaust toward the turbine controlling both the velocity and angle the exhaust contacts the This gives the ECU the ability dynamically the boost pressure any given engine speed and Improving performance and fuel economy
Fully open the velocity slows and the angle decreased therefore the turbine and compressor turn slower producing less When the vanes close increasing the velocity and therefore increasing turbine and pressor speed, producing higher boost anytime needed across the entire operating range the
