Question

technician a says that a wastegate is designed to direct waste gases to the intake manifold. technician b says that a blow - off valve allows excess boost pressure to \blow off\ into the atmosphere. who is correct?

a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

Explanation:

A wastegate directs waste gases away from the turbine (not to the intake manifold). A blow - off valve (also known as a dump valve) is designed to release excess boost pressure into the atmosphere. So Technician A is wrong and Technician B is correct.

Answer:

b. Technician B
