Name four important jobs performed by a good engine lubricant.
-
Lubricates, cools, cleans, and seals
-
Clean, wax, vacuum, wash
Correct Answer
A. Lubricates, cools, cleans, and sealsExplanation
A good engine lubricant performs four important jobs. Firstly, it lubricates the moving parts of the engine, reducing friction and preventing wear and tear. Secondly, it helps in cooling the engine by dissipating heat generated during the combustion process. Thirdly, it cleans the engine by removing dirt, debris, and sludge, ensuring optimal performance. Lastly, it seals the gaps between engine components, preventing leakage and maintaining proper pressure.Rate this question:

- 3.
Which engine lubrication system utilizes a trough in the crankcase?
-
Splash system
-
Ejection pump system
-
Constant level system
Correct Answer
A. Constant level systemExplanation
The constant level system utilizes a trough in the crankcase to ensure a consistent oil level. In this system, oil is continuously supplied to the trough, and excess oil is returned to the oil pan. This helps to maintain a steady lubrication of the engine components, preventing excessive wear and overheating. The constant level system is commonly used in smaller engines where a pressurized oil system is not necessary.Rate this question:

- 4.
Which small engine lubrication system is similar to the system used on automobiles?
-
Barrel type pump system
-
Full pressure system
Correct Answer
A. Full pressure systemExplanation
The correct answer is full pressure system. This is because, similar to automobiles, a full pressure system in small engine lubrication also uses an oil pump to circulate oil under pressure to all the moving parts of the engine. This ensures proper lubrication and reduces friction, heat, and wear, thereby increasing the engine's efficiency and lifespan. On the other hand, a barrel type pump system does not provide full pressure lubrication and is not commonly used in small engines.Rate this question:

Babbitt metal used as a bearing material is an alloy of three metals. name them.
-
Tin, copper, antimony
-
Gold, silver, bronze
Correct Answer
A. Tin, copper, antimonyExplanation
Babbitt metal is commonly used as a bearing material due to its low friction and excellent load-bearing properties. It is an alloy made up of tin, copper, and antimony. Tin provides the base for the alloy, while copper improves its strength and antimony enhances its hardness and wear resistance. This combination of metals creates a durable and reliable material for bearings, allowing for smooth and efficient operation in various applications.Rate this question:

-
- 9.
Type of oil refers to its______________.
-
Service classification
-
Grade
-
Maximun operating temperature
Correct Answer
A. Service classificationExplanation
The type of oil refers to its service classification, which is a categorization based on the specific requirements and performance characteristics of the oil. This classification helps determine the suitability of the oil for different types of engines or machinery, taking into account factors such as viscosity, additives, and performance under various operating conditions. It allows users to select the right oil for their specific needs and ensures optimal performance and protection for the equipment.Rate this question:
-
- 10.
Most four-cycle engine manufacturers recommend oils supplimented by additives.
-
True
-
False
Correct Answer
A. TrueExplanation
Most four-cycle engine manufacturers recommend oils supplemented by additives because these additives help improve the performance and longevity of the engine. Additives can enhance lubrication, reduce friction, prevent corrosion, and clean the engine. They can also provide extra protection against wear and tear, especially in high-stress conditions. Therefore, using oils with additives can help optimize the engine's efficiency and ensure its smooth operation.Rate this question:
-
- 11.
What is the purpose of detergents/dispersants in oils?
-
Suspend dirt and sludge in the oil where contaminents can be trapped by a filter or readily drained.
-
Keeps the car clean
-
Makes oil less expensive
Correct Answer
A. Suspend dirt and sludge in the oil where contaminents can be trapped by a filter or readily drained.Explanation
Detergents/dispersants in oils serve the purpose of suspending dirt and sludge in the oil. This allows contaminants to be trapped by a filter or easily drained from the oil.Rate this question:
-
- 12.
Why are some oils with additives not suitable for two-cycle engine use?
-
They are too expensive and hard to find
-
They make the engine harder to start
-
Some oils do not burn completely and leaves a residue that fouls spark plugs and clogs exhaust ports.
Correct Answer
A. Some oils do not burn completely and leaves a residue that fouls spark plugs and clogs exhaust ports.Explanation
Some oils with additives are not suitable for two-cycle engine use because they do not burn completely and leave a residue. This residue can foul spark plugs and clog exhaust ports, leading to poor engine performance and potential damage.Rate this question:
-
- 13.
A high viscocity oil would ______________.
-
Be thin
-
Be suitable for high temperature use
Correct Answer
A. Be suitable for high temperature useExplanation
A high viscosity oil would be suitable for high temperature use because viscosity refers to the thickness or resistance to flow of a fluid. In the context of oil, high viscosity means that the oil is thick and has a slow flow rate. This is beneficial in high temperature environments because it helps the oil maintain its lubricating properties and prevents it from breaking down or thinning out too quickly under the heat. Therefore, a high viscosity oil would be able to withstand and perform well in high temperature conditions.Rate this question:
-
- 14.
Several types of positive displacement oil pumps are used in pressurized lubrication systems.
-
Yes
-
No
Correct Answer
A. YesExplanation
The given statement states that several types of positive displacement oil pumps are used in pressurized lubrication systems. The answer "yes" is correct because it confirms the statement. Positive displacement oil pumps are commonly used in pressurized lubrication systems to ensure a constant flow of oil to the various parts of the system. These pumps work by trapping a fixed amount of oil and then displacing it to create pressure, thus providing efficient lubrication to the machinery or equipment.Rate this question:
-
- 15.
Name three type of oil filters in use.
-
Bypass, shunt, full flow
-
Paper, pleated, stacked
Correct Answer
A. Bypass, shunt, full flowExplanation
The correct answer is bypass, shunt, full flow. These are the three types of oil filters commonly used in automotive engines. Bypass filters allow a small portion of the oil to bypass the filter, providing continuous filtration. Shunt filters divert a portion of the oil flow through an external filter, increasing filtration capacity. Full flow filters, on the other hand, allow all the oil to pass through the filter before reaching the engine, providing maximum filtration efficiency.Rate this question:
-
- 16.
Generally, the oil filter element is replaceable.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because oil filter elements are designed to be replaceable. The purpose of an oil filter is to remove contaminants from the engine oil, and over time these contaminants can accumulate and clog the filter. By making the filter element replaceable, it allows for easy maintenance and ensures that the filter continues to effectively clean the oil.Rate this question:
