1 / 5

Question 2: How does a centrifugal overspeed trip mechanism operate?

A) It uses a hydraulic piston to regulate engine speed

C) It relies on centrifugal force to actuate a trip mechanism that stops the engine when a certain speed is exceeded

D) It uses an electronic sensor to monitor engine speed and trigger an alarm

B) It employs a spring-loaded valve to control fuel flow

2 / 5

Question 5: Which of the following is a common maintenance check for the centrifugal overspeed trip mechanism?

C) Replacing the engine oil filter

A) Checking the engine coolant level

D) Calibrating the turbocharger pressure

B) Inspecting the condition of the centrifugal weights and springs

3 / 5

Question 4: What happens to the centrifugal overspeed trip mechanism if the engine speed returns to normal after an overspeed condition?

C) The trip mechanism requires a complete engine shutdown for reset

B) The trip mechanism automatically resets once the speed decreases

A) The trip mechanism remains engaged until manually reset

D) The mechanism continues to trip intermittently
