12 / 12

Question 4:
In a simple hydraulic governor, how is the feedback from the engine speed used to control fuel delivery?

C) It controls the temperature of the hydraulic fluid.

B) It changes the position of the flyweights, which in turn adjusts the fuel pump.

D) It alters the pressure in the engine's cooling system.

A) It directly adjusts the engine’s ignition timing.
