Technician A says that VGT engines can electronically vary turbocharger boost pressure. Technician B says that boost pressure from VGTs is typically higher than boost pressure from fixed-geometry turbochargers. Who is correct?
A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because VGT (Variable Geometry Turbocharger) engines can electronically adjust the turbocharger's vanes to vary boost pressure. Technician B is also correct because VGTs can provide higher boost pressure compared to fixed-geometry turbochargers due to their ability to optimize airflow across a range of engine speeds.
