Since the VGT (variable-geometry turbocharger) pressure ratios are higher, more discharge heat is generated by the compressor wheel, which often requires:
A)titanium alloys"
B)aluminum alloys"
C)steel alloys
D)forged aluminum alloy"

Question

Quizplus · Accepted Answer

Titanium alloys are used in VGTs because they can withstand the higher discharge heat generated by the compressor wheel.

Since the VGT (Variable-Geometry Turbocharger) Pressure Ratios Are Higher, More
