Question 1:
What is the primary function of a simple hydraulic governor in an engine?

A) To regulate engine speed by adjusting the fuel flow

B) To control the engine temperature by adjusting coolant flow

C) To manage the engine's ignition timing

D) To control the air intake to the engine

3 / 6

Question 2:
How does a simple hydraulic governor detect changes in engine speed?

A) By measuring the oil pressure in the hydraulic system

D) By checking the temperature of the engine coolant

B) By sensing the position of the throttle lever

C) By monitoring the centrifugal force generated by a flyweight mechanism

4 / 6

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

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.

C) It controls the temperature of the hydraulic fluid.

5 / 6

Question 3:
What component in a simple hydraulic governor adjusts the fuel flow based on engine speed?

A) Centrifugal flyweights

B) Hydraulic pump

D) Pressure regulator

C) Throttle valve

6 / 6

Question 5:
What happens to the hydraulic governor’s throttle valve when engine speed increases?

B) It closes to decrease fuel flow.

D) It alternates rapidly to stabilize the engine speed.

A) It opens to increase fuel flow.

C) It remains unchanged.
