Technician A says a fixed geometry turbocharger requires pressure relief because it operates over a wide rpm band. Technician B says a wastegate is commonly used to control the speed of the turbine in automobile engines. Who is correct?
A)Technician A
B)Technician B
C)Both technicians
D)Neither technician

Question

Quizplus · Accepted Answer

Technician B is correct because a wastegate is indeed used to control the speed of the turbine in turbocharged engines, preventing it from spinning too fast and producing too much boost, which could potentially damage the engine. Technician A's statement is incorrect because the need for pressure relief in a turbocharger is not specifically due to its fixed geometry but rather to prevent excessive boost pressure regardless of the turbocharger's design.
