Five Functions Of Oil In An Engine - Quiz

2.

Engine without proper lubrication can get hot enough to melt engine components.
- True
- False
Correct Answer

A. True

Explanation

Without proper lubrication, the friction between engine components increases, leading to overheating. This excessive heat can cause the engine components to reach their melting point, resulting in damage and potential failure of the engine. Therefore, it is true that an engine without proper lubrication can get hot enough to melt engine components.

3.

If oil flow stops in an engine what will happen?
- Increased temperature
- Loss of power
- Reduction of fuel mileage
- All of the above
Correct Answer

A. All of the above

Explanation

If oil flow stops in an engine, it will lead to increased temperature because oil acts as a lubricant and coolant, preventing friction and heat buildup. This increased temperature can cause various issues, including loss of power as the engine components may seize or fail to operate efficiently. Additionally, the lack of proper lubrication can result in increased friction, leading to a reduction in fuel mileage. Therefore, all of the given options are correct consequences of oil flow stopping in an engine.

4.

The cleaners in oil are called what?
- Soaps
- Detergents
- Microscrubbers
- Reducers
Correct Answer

A. Detergents

Explanation

Detergents are the correct answer because they are commonly used as cleaning agents in oil. Detergents have the ability to remove dirt, grease, and other contaminants from surfaces, making them effective cleaners for oil spills or stains. Soaps, on the other hand, are not specifically designed for cleaning oil and may not be as effective. Microscrubbers and reducers are not commonly used terms for cleaners in oil, making them incorrect choices.

Rate this question:
5.

What element does a Ferrous metal contain?
- Oxygen
- Cadmium
- Iron
- Aluminum
Correct Answer

A. Iron

Explanation

Ferrous metals are metals that contain iron as their main component. Iron is a key element in ferrous metals and gives them their characteristic properties such as strength and magnetic properties. Oxygen, cadmium, and aluminum are not considered ferrous metals as they do not contain iron as the main component. Therefore, the correct answer is iron.

6.

What rust causing element does oil protect metal engine parts from?
- Hydrogen
- Oxygen
- Carbon
- Helium
Correct Answer

A. Oxygen

Explanation

Oil protects metal engine parts from rust caused by oxygen. Oxygen is known to cause oxidation, which leads to the formation of rust on metal surfaces. By creating a barrier between the metal and oxygen, oil prevents the metal from coming into contact with oxygen and thus protects it from rusting.

Rate this question:
7.

What two engine components does oil help seal the area between to increase power?
- Cylinder and Head
- Crankshaft and Connecting Rod
- Lifter and Cam
- Piston and Cylinder
Correct Answer

A. Piston and Cylinder

Explanation

Oil helps seal the area between the piston and cylinder to increase power. The piston moves up and down within the cylinder, and the oil forms a thin film between them, reducing friction and allowing for smoother movement. This helps to increase the efficiency of the engine and ultimately leads to more power output.

Rate this question:
8.

What percentage of over call cooling can oil be responsible for?
- 20%
- 45%
- 80%
- 100%
Correct Answer

A. 20%

Explanation

Oil can be responsible for 20% of over call cooling. This means that oil contributes to a small portion of the overall cooling process. It is likely that there are other factors or mechanisms that contribute to the majority of the cooling.
