Fuel system And Governors

Question 1

Give 2 reasons Governors are fitted to Diesel (Internal Combustion) Engines.

Answer 1

• To prevent overloading and over-speeding of the engine
• To keep the engine revs constant relative to the position of the throttle

Question 2

Name the force which the mechanical governor relies on for it to operate correctly.

Answer 2

Centrifugal Force

Question 3

What is Centrifugal force? (Kid definition)

Answer 3

Centrifugal force is the energy of a moving object in a circle trying to stay in a straight line when it cannot. It’s the result of inertia, which is the tendency of an object to resist rest or motion.

Question 4

Centrifugal force v Centripetal force

Answer 4

Centripetal force is the force REQUIRED for circular motion. Centrifugal force is the force that makes something flee from the center

Question 5

What type of injector gives the quickest response when a signal to inject fuel is given by the system controller?

Answer 5

Solenoid Injectors - A needle is lifted allowing high pressure fuel to be injected into the engine
