MDE 21 Q2

1 / 6

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.

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

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

2 / 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.

3 / 6

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

C) Throttle valve

D) Pressure regulator

A) Centrifugal flyweights

B) Hydraulic pump

4 / 6

Question 6:
What is the role of the hydraulic fluid in a simple hydraulic governor?

B) To transmit force from the flyweights to the throttle mechanism

A) To lubricate the engine components

C) To cool the engine during operation

D) To measure engine speed

5 / 6

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

D) By checking the temperature of the engine coolant

A) By measuring the oil pressure in the hydraulic system

B) By sensing the position of the throttle lever

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

6 / 6

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

D) To control the air intake to the engine

C) To manage the engine's ignition timing
